- An inkjet head is composed of a nozzle having an orifice, wherein the diameter of the orifice is not more than 50 ⁇ m, a pressure generator, a liquid container, a filter, and so on.
- Each component is processed precisely and therefore each inkjet head has multiple inkjet nozzles. Therefore, before shipping, the inkjet head is tested with test ink to ensure that all the components work normally and not result in a jetting failure.
- the test ink used for the test must be cleaned up to avoid leak of the test ink at the time of transportation, or to avoid nozzle clog due to aggregation of the test ink.

- Patent Literature 5 discloses that the number of the carbon atoms is preferably 4 to 12, more preferably 5 to 12.
- conventional cleaning liquid has a lack of cleaning property. Even if the conventional cleaning liquid has enough cleaning property, the cleaning liquid has disadvantages such as low filling property of the inkjet ink, which causes jetting defect.
- the cleaning liquied swells adhesive agent in the head to decrease strength of the head, or the cleaning liquid erodes metal portions of the liquid flow channel, when it is storaged before filling the inkjet ink, which may decrease jetting stability.
- the cleaning filling liquid which is the means for solving the aforementioned problems, comprises: water; and 10.0% by mass to 45% by mass per whole amount of the cleaning filling liquid of an amide compound of structural formula (1).
- the present invention provides the cleaning filling liquid for inkjet device having high cleaning performance as a cleaning liquid and excellent function as a filling liquid that does not cause problems such as aggregation of test ink, or erosion of metal portions of the liquid flow channel, in storage term.

- the cleaning filling liquid further comprises a polyether modified silicone oil.
- the present invention provides a cartridge including: a container containing the cleaning filling liquid according to the embodiments.
- the present invention provides a cleaning filling method for an ink cartridge comprising: cleaning a liquid flow channel by allowing passage of the cleaning filling liquid according the first or second embodiments, and filling the cleaning filling liquid in the liquid flow channel.
- the present invention also includes an inkjet recording device comprising: the flow channel, wherein the flow channel is cleaned and filled by the cleaning filling method according to the fourth embodiment.
- the inventors have determined that the cleaning filling liquid containing the amide compound of formula (1) is easily mixed with the test ink and thus enhances cleaning performance.
- the amide compound has a function to mix between water-soluble solvent having high equilibrium water content and relatively hydrophobic organic solvent uniformly. Therefore, the amide compound is preferably used with organic solvent.
- the amide compound prevents not only aggregation of cleaning residues but also aggregation of the inkjet ink, because the cleaning filling liquid is mixed with the inkjet ink immediately, in filling the cleaning filling liquid.
- the amide compound has a high moisture-retaining property and drying resistance, because the amide compound has a high boiling point (216° C.) and high equilibrium water content (39.2% by mass at 23° C. and 80% RH). Therefore, the cleaning filling liquid is available not only for the cleaning liquid but also as a filling liquid or partially filling liquid.
- the amount of the amide compound is preferably 10.0% by mass to 45.0% by mass per whole amount of the cleaning filling liquid. When the amount is less than 10% by mass, the aforementioned functions may not be obtained adequately. When the amount is more than 45.0% by mass, the cleaning filling liquid may erode a portion of the liquid flow channel to adversely affect jetting property.
- a silicone oil is included in for the cleaning filling liquid.

- lower amount of the silicone oil must be used, because the silicone oil decreases storage stability.
- higher amount of the silicone oil can be used.
- the cleaning filling liquid which is left on the surface of the liquid flow channel or head, acts as coat to prevent the inkjet ink to adhere on the liquid flow channel or the head.
- the amount of the silicone oil per whole amount of the cleaning filling liquid is preferably 0.1% by mass to 5.0% by mass, more preferably 1.0% by mass to 2.5% by mass. When the amount is less than 0.1% by mass, the aforementioned functions may not be obtained. When the amount is more than 5.0% by mass, storage stability of the cleaning filling liquid may decrease.

- the polyether modified silicone oil is preferred, when a surfactant is used in the cleaning filling liquid.
- the polyether modified silicone oil has appropriate dispersion property to liquid better than dimethyl silicone oil, that increases storage stability of the cleaning filling liquid. Therefore, the polyether modified silicone oil has a function to prevent fixing.
- the polyether modified silicone oil has a polyoxyalkylene group, which is an adduct of ethylene oxide and propylene oxide, in dimethyl siloxane. Therefore, hydrophile-Lipophile Balance (HLB) can be controlled variedly depending on liquid for ejection by adjusting number of the polyoxyalkylene group. Normally, HLB of the modified silicone oil is 5 to 10, and HLB of the non-modified silicone oil is 0.

Abstract
Description
- This patent application is based on and claims priority pursuant to 35 U.S.C. §119 to Japanese Patent Application No. 2012-019920, filed on Feb. 1, 2012, in the Japan Patent Office, the entire disclosure of which is hereby incorporated by reference herein.
- The present invention relates to a cleaning filling liquid, a cartridge, a cleaning filling method, and an inkjet recording device.
- Ink cartridge has a liquid flow channel such as an ink flow member between ink storage and ink outlet. When the ink cartridge is recycled, the liquid flow channel must be cleaned to assure performance of the recycled cartridge.
- An inkjet head is composed of a nozzle having an orifice, wherein the diameter of the orifice is not more than 50 μm, a pressure generator, a liquid container, a filter, and so on. Each component is processed precisely and therefore each inkjet head has multiple inkjet nozzles. Therefore, before shipping, the inkjet head is tested with test ink to ensure that all the components work normally and not result in a jetting failure. The test ink used for the test must be cleaned up to avoid leak of the test ink at the time of transportation, or to avoid nozzle clog due to aggregation of the test ink.
- For cleaning up the test ink, Patent Literature 1, Japanese Patent Application Laid-Open (JP-A) No. 2000-127419, discloses a solution including a main solvent such as water, surfactant, and wetting agent without solid content. Patent Literature 2, JP-A No. 2001-49292, discloses maintenance liquid and cleaning liquid to clean up residual materials that adhere to inside of nozzle.
- The filling liquid is filled and left in inkjet recording apparatus until inkjet ink is filled. Therefore, aqueous solution including surfactant is used to ensure refilling property of the inkjet ink. Patent Literature 3, JP-A No. 2010-227729, discloses a filling liquid including silicone oil.
- Patent Literature 4, JP-A No. 2005-8735, discloses a cleaning liquid including N,N-dimethyl-β-methoxypropionamide, water, and surfactant.
- Patent Literature 5, JP-A No. 2005-47885, discloses a cleaning liquid including N,N-dimethyl-β-alkoxypropionamide, wherein the alkoxy group has 3 to 18 of carbon atoms. Patent Literature 5 discloses that the number of the carbon atoms is preferably 4 to 12, more preferably 5 to 12.
- Recently, an image having high resolution or patterning accuracy is required in inkjet recording. Therefore, smaller curving tolerance of jetting liquid and greater accuracy of jetting property is required. In addition, because the inkjet ink tends to have a high solid content, it becomes more difficult to clean up the liquid flow channel, particularly inside of the nozzle, so as to prevent defects in the recycled cartridge.
- Therefore, conventional cleaning liquid has a lack of cleaning property. Even if the conventional cleaning liquid has enough cleaning property, the cleaning liquid has disadvantages such as low filling property of the inkjet ink, which causes jetting defect. In addition, the cleaning liquied swells adhesive agent in the head to decrease strength of the head, or the cleaning liquid erodes metal portions of the liquid flow channel, when it is storaged before filling the inkjet ink, which may decrease jetting stability.
- The cleaning filling liquid, which is the means for solving the aforementioned problems, comprises: water; and 10.0% by mass to 45% by mass per whole amount of the cleaning filling liquid of an amide compound of structural formula (1).
- The present invention provides the cleaning filling liquid for inkjet device having high cleaning performance as a cleaning liquid and excellent function as a filling liquid that does not cause problems such as aggregation of test ink, or erosion of metal portions of the liquid flow channel, in storage term.
-
FIG. 1 shows a perspective view of an inkjet recording apparatus. -
FIG. 2 schematically shows an example of an entire construction of the inkjet recording apparatus. -
FIG. 3 schematically shows an enlarged view of an example of an inkjet head suitable for use in the inkjet recording apparatus. -
FIG. 4 shows a schematic enlarged view of an example of an inkjet head of the embodiment. -
FIG. 5 shows an enlarged sectional view of an example of an inkjet head of the embodiment. - The embodiments of the present invention will be described in detail.
- In a first embodiment the present invention provide a cleaning filling liquid which includes water; and 10.0% by mass to 45% by mass per whole amount of the cleaning filling liquid of an amide compound of structural formula (1).
- Ina second embodiment the cleaning filling liquid further comprises a polyether modified silicone oil.
- In a third embodiment the present invention provides a cartridge including: a container containing the cleaning filling liquid according to the embodiments.
- In a fourth embodiment the present invention provides a cleaning filling method for an ink cartridge comprising: cleaning a liquid flow channel by allowing passage of the cleaning filling liquid according the first or second embodiments, and filling the cleaning filling liquid in the liquid flow channel.
- The present invention also includes an inkjet recording device comprising: the flow channel, wherein the flow channel is cleaned and filled by the cleaning filling method according to the fourth embodiment.
- The inventors have determined that the cleaning filling liquid containing the amide compound of formula (1) is easily mixed with the test ink and thus enhances cleaning performance. The amide compound has a function to mix between water-soluble solvent having high equilibrium water content and relatively hydrophobic organic solvent uniformly. Therefore, the amide compound is preferably used with organic solvent. In addition, the amide compound prevents not only aggregation of cleaning residues but also aggregation of the inkjet ink, because the cleaning filling liquid is mixed with the inkjet ink immediately, in filling the cleaning filling liquid. Moreover, the amide compound has a high moisture-retaining property and drying resistance, because the amide compound has a high boiling point (216° C.) and high equilibrium water content (39.2% by mass at 23° C. and 80% RH). Therefore, the cleaning filling liquid is available not only for the cleaning liquid but also as a filling liquid or partially filling liquid.
- The amount of the amide compound is preferably 10.0% by mass to 45.0% by mass per whole amount of the cleaning filling liquid. When the amount is less than 10% by mass, the aforementioned functions may not be obtained adequately. When the amount is more than 45.0% by mass, the cleaning filling liquid may erode a portion of the liquid flow channel to adversely affect jetting property.
- In a preferred embodiment, a silicone oil is included in for the cleaning filling liquid. The silicone oil functions to prevent a tiny residual material to adhere on the liquid flow channel or head, because the silicone oil acts as a mold release agent. When the silicone oil is used solely and not according the present invention, lower amount of the silicone oil must be used, because the silicone oil decreases storage stability. However, when the silicone oil is used in combination with the amide compound as according to the invention, higher amount of the silicone oil can be used. In this case, the cleaning filling liquid, which is left on the surface of the liquid flow channel or head, acts as coat to prevent the inkjet ink to adhere on the liquid flow channel or the head.
- The amount of the silicone oil per whole amount of the cleaning filling liquid is preferably 0.1% by mass to 5.0% by mass, more preferably 1.0% by mass to 2.5% by mass. When the amount is less than 0.1% by mass, the aforementioned functions may not be obtained. When the amount is more than 5.0% by mass, storage stability of the cleaning filling liquid may decrease.
- The silicone oil is a linear polymer composed of difunctional siloxane units, which has relatively low degree of polymerization. In one preferred embodiment, a modified silicone oil may be used.
- The modified silicone oil is a compound that apart of methyl group of the dimethylsilicone oil is replaced with an organic group. The modified silicone oil may be classified as a reactive silicone oil and a non-reactive silicone oil.
- Examples of the reactive silicone oil include an amino modified compound, an epoxy modified compound, a carboxy modified compound, and a methacryl modified compound. Examples of the non-reactive silicone oil include a polyether modified compound, a methyl styryl modified compound, a long-chain alkyl modified compound, a fluoro modified compound, and a phenyl modified compound.
- Among them, the polyether modified silicone oil is preferred, when a surfactant is used in the cleaning filling liquid. The polyether modified silicone oil has appropriate dispersion property to liquid better than dimethyl silicone oil, that increases storage stability of the cleaning filling liquid. Therefore, the polyether modified silicone oil has a function to prevent fixing. In addition, the polyether modified silicone oil has a polyoxyalkylene group, which is an adduct of ethylene oxide and propylene oxide, in dimethyl siloxane. Therefore, hydrophile-Lipophile Balance (HLB) can be controlled variedly depending on liquid for ejection by adjusting number of the polyoxyalkylene group. Normally, HLB of the modified silicone oil is 5 to 10, and HLB of the non-modified silicone oil is 0.
- In a further embodiment, the cleaning filling liquid may include not only the amide compound, water, and the silicone oil, but also at least one of a water-soluble organic solvent, a surfactant, and other additives conventionally known.
- Water may be used as solvent in combination with the water-soluble organic solvent.
- The amount of the water-soluble organic solvent is preferably 5% by mass to 20% by mass per whole amount of the cleaning filling liquid.
- Examples of the water-soluble organic solvent include polyhydroxy alcohols such as ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, polypropylene glycol, 1,3-butanediol, 3-methyl-1,3-butanediol, 1,5-pentanediol, 1,6-hexanediol, glycerin, diglycerin, 1,2,3-butanetriol, 1,2,4-butanetriol, 1,2,6-hexanetriol, and petriol; polyhydroxy alcohol alkyl ethers such as ethyleneglycolmonoethylether, ethyleneglycolmonobutylether, diethyleneglycolmonomethylether, diethyleneglycolmonoethylether, diethyleneglycolmonobuthylether, tetraethyleneglycolmonomethylether, and propyleneglycolmonoethylether; polyhydroxy alcohol aryl ethers such as ethyleneglycolmonophenylether, and ethyleneglycolmonobenzilether; nitrogen-containing heterocyclic compounds such as N-methyl-2-pyrolidone, N-hydroxyethyl-2-pyrolidone, 2-pyrolidone, 1,3-dimethylimidazolidinone, and ε-caprolactam; amides such as formamide, N-methylformamide, and N,N-dimethylformamide; amines such as monoethanolamine, diethanolamine, triethanolamine, monoethylamine, diethylamine, and triethylamine; sulfur-containing compounds such as dimethylsulfoxide, sulfolane, and thio-diethanol; propylene carbonate, ethylene carbonate, and γ-butyrolactone.
- In addition, by use of a water-soluble organic solvent having a high equilibrium water content, even when water in the cleaning filling liquid evaporates and reaches moisture equilibrium, the water-soluble organic solvent retains a large amount of water, thereby suppressing outstanding rise in viscosity of the cleaning filling liquid.
- In one preferred embodiment, a water-soluble organic solvent having a high equilibrium water content means a water-soluble organic solvent having a equilibrium water content of 30% by mass or more, and preferably 40% by mass or more, at a temperature of 23° C. and a humidity of 80%. Note that the equilibrium water content means the water content when a mixture of a water-soluble organic solvent and water is opened at a constant temperature and humidity in the air, and evaporation of water in the solution and absorption of water from the air into the ink are at equilibrium state.
- Specifically, a saturated potassium chloride aqueous solution is used to control temperature and humidity in the desiccator, the temperature and humidity in a desiccator are kept at 23° C.±1° C. and 80%±3% respectively, petri dishes each containing 1 g of the water-soluble organic solvent weighed are stored inside this desiccator until no mass change occurs, and the equilibrium water content (%) is calculated by the expression:
-
Equilibrium water content(%)=(amount of water absorbed in organic solvent)/(amount of organic solvent+water absorbed in organic solvent)×100. - In this embodiment, a polyol having an equilibrium water content of 30% by mass or more at a temperature of 23° C. and a humidity of 80% is preferably used as the water-soluble organic solvent having the high equilibrium water content. Specific examples of the water-soluble organic solvent include 1,2,3-butanetriol (boiling point: 175° C./33 hPa, 38% by mass), 1,2,4-butanetriol (boiling point: 190° C. to 191° C./24 hPa, 41% by mass), glycerin (boiling point: 290° C., 49% by mass), diglycerin (boiling point: 270° C./20 hPa, 38% by mass), diethylene glycol (boiling point: 245° C., 43% by mass), triethylene glycol (boiling point: 285° C., 39% by mass), tetraethylene glycol (boiling point: 324° C. to 330° C., 37% by mass), and 1,3-butanediol (boiling point: 203° C. to 204° C., 35% by mass). Of these, glycerin is preferably used, because the viscosity of glycerin decreases upon containing water.
- The surfactant is optionally used for increasing cleaning performance by decreasing surface tension of liquid, increasing mixing stability of the cleaning filling liquid, and increasing filling property of the inkjet ink.
- Examples of a suitable surfactant include a fluorochemical surfactant, an anionic surfactant, a cationic surfactant, a non-ionic surfactant, and an amphoteric surfactant.
- The amount of the surfactant is 0.01% by mass to 5.0% by mass of the cleaning filling liquid. When the amount is within the range, increased cleaning performance is obtained.

Then, it is guided by the conveyingguide 153 at the leading end and is pressed against the conveyingbelt 151 by the leadingend pressure roller 155 to change the convey direction substantially by 90°. - Meanwhile, the conveying
belt 151 is charged by the chargingroller 156, and thepaper 142 is electrostatically adsorbed and conveyed by the conveyingbelt 151. Then, the recording heads 134 are driven according to image signals while thecarriage 133 is moved. Ink droplets are ejected on the pausedpaper 142 for recording one-line. Then, thepaper 142 is conveyed by a certain rate for recording the next line. Receiving a recording end signal or a signal indicating the rear end of thepaper 142 has reached the recording area, the recording operation is terminated and thepaper 142 is ejected to thepaper output tray 103. - When it is detected that the remaining amount of the recording ink in the
subtank 135 is nearly to the end, a certain amount of recording ink is supplied to thesubtank 135 from theink cartridge 201. - In this inkjet recording apparatus, when the recording ink in the
ink cartridge 201 of the present invention is used up, the case of theink cartridge 201 is disassembled and only the ink pouch contained therein can be exchanged. Theink cartridge 201 allows for stable recording ink supply even in a vertical and front mounting structure. Therefore, when theapparatus body 101 is installed with the top being blocked by something, for example, theink cartridge 201 can be housed in a rack. Even if something is placed on the top surface of theapparatus body 101, theink cartridge 201 can be easily replaced. - Here, the explanation is made with reference to an application in a serial type, i.e. shuttle type, inkjet recording apparatus in which the carriage scans is described. A line type inkjet recording apparatus having a line head is also applicable.
- The inkjet ink of the embodiment is applicable to various recording in an inkjet recording system such as inkjet recording printers, facsimiles, copy machines, and printer/fax/copy complex machines.
- An inkjet head of the present invention will be described below.
-
FIG. 4 shows an enlarged sectional view of an example of an inkjet head.FIG. 5 shows an enlarged sectional view of an example of the main portion of an inkjet head. - The inkjet head contains a
frame 10 having formed therein a cavity serving as an ink supply port and acommon liquid chamber 1 b, aflow path 20 having formed therein a cavity serving as aresistance portion 2 a and a pressurizedliquid chamber 2 b and alink port 2 c linked to anozzle 3 a, anozzle plate 30 forming thenozzle 3 a, anoscillation plate 60 having aconvex portion 6 a, adiaphragm portion 6 b and anink inflow port 6 c, a laminated piezoelectric element 50 joined with anadhesive layer 70 to theoscillation plate 60, and a base 40 that fixes the laminated piezoelectric element 50. - The
base 40 is made from a barium titanate ceramic and has two laminated piezoelectric elements 50 disposed in row and joined thereto. - The laminated piezoelectric element 50 is obtained by alternately laminating piezoelectric layers of lead zirconium titanate (PZT), each having a thickness of 10 μm to 50 μm, and internal electrode layers composed of silver-palladium (AgPd), each layer having a thickness of several micrometers. The internal electrode layers are connected to the external electrodes at both ends.
- The laminated piezoelectric element 50 is split in a combtooth manner by half-cut dicing, and each section is used as a
drive portion 5 f and asupport portion 5 g (non-drive portion). The external side of one of two external electrodes is restricted in length by machining such as notching so that it can be split by half-cut dicing, and the sections obtained serve as a plurality of individual electrodes. The other side is conductive, without being split by dicing, and serves as a common electrode. - An FPC is joined by soldering to individual electrodes of the drive portion. Further, in the common electrode, an electrode layer is provided at the end portion of the laminated piezoelectric element 50 and bent to joint to the ground electrode of the FPC. A Driver IC is mounted on the FPC, and drive voltage application to the
drive portion 5 f is controlled thereby. - The
oscillation plate 60 is formed from the thin-film diaphragm portion 6 b, the island-shaped convex portion (island portion) 6 a that is formed in the central zone of thediaphragm portion 6 b, joined to the laminated piezoelectric element 50 and serves as thedrive portion 5 f, a thick-film portion including a beam for connection to the support portion, and an opening serving as theink inflow port 6 c, by two-layer stacking a Ni plated film obtained by an electroforming method. The thickness of the diaphragm portion is 3 μm and the width is 35 μm (one side). Joining between the island-shapedconvex portion 6 a of theoscillation plate 60 and thedrive portion 5 f of the laminated piezoelectric element 50, and between theoscillation plate 60 and theframe 10 is performed with the patternedadhesive layer 70 including a gap material. - A silicon single-crystal substrate is used for the
flow path plate 20, and the plate is patterned by an etching method to form a cavity serving as thefluid resistance portion 2 a and pressurizedfluid chamber 2 b and a through port serving as thelink port 2 c in a position corresponding to thenozzle 3 a. - A portion remaining after etching serves as a
partition wall 2 d of thepressurized fluid chamber 2 b. Further, a portion of decreased etching width is provided in the head, and this portion serves as thefluid resistance portion 2 a. - The
nozzle plate 30 is formed of a metal material, e.g., of a Ni plated film obtained by electroforming and has a large number ofnozzles 3 a serving as fine discharge ports for inkjet ink droplets. Thenozzles 3 a are formed to have a horn-like inner (internal) shape (may also have a substantially cylindrical rod-like or barrel-like shape). The diameter of thenozzle 3 a is 20 μm to 35 μm, as a diameter on the ink droplet discharge port. The nozzle pitch in each row is 150 dpi. - The ink discharging surface (nozzle surface) of the
nozzle plate 30 has an ink repellent layer. - The ink repellent layer is formed of resin such as fluorine resin and silicone resin, fluorine series silane coupling agent, and metal-resin compound plating such as PTFE-Ni eutectoid plating. In this embodiment, fluorine resin and silicone resin are effectively used.
- The
frame 10 having formed therein a cavity serving as an ink supply port and acommon liquid chamber 1 b is formed by resin. - In the inkjet head of the above-descried configuration, when a drive waveform (a pulsed voltage of 10 V to 50 V) is applied to the
drive portion 5 f according to a recording signal, a displacement in the lamination direction is induced in thedrive portion 5 f, the pressurizedliquid chamber 2 b is pressurized via theoscillation plate 60, the pressure therein is increased, and an ink droplet is discharged from thenozzle 3 a. - As the discharge of ink droplet is completed, the ink pressure inside the pressurized
liquid chamber 2 b is reduced, a negative pressure is generated inside the pressurizedliquid chamber 2 b by the inertia of ink flow and discharge process of the drive pulse, and then a transition is made to an ink filling step. At this time, the ink supplied from the ink tank flows into thecommon liquid chamber 1 b, and the pressurizedliquid chamber 2 b is filled with the ink from thecommon liquid chamber 1 b via theink inflow port 6 c and through thefluid resistance portion 2 a. - The
fluid resistance portion 2 a effectively attenuates residual pressure oscillations after discharging and also creates resistance to a refill by surface tension. By appropriately selecting the fluid resistance portion, it is possible to attain a balance between the attenuation of residual pressure and refill, and to shorten time (drive period) to the next ink droplet discharge operation. - When the inkjet head is cleaned with the aforementioned cleaning filling liquid, vibration by tiny driving of piezoelectric actuator such as piezoelectric element may be used, wherein the vibration does not generate ejection of the cleaning filling liquid. Cleaning efficiency is enhanced by using the vibration.
- The nozzle plate and inkjet head are applicable not only for the inkjet recording apparatus (image forming apparatus) but also for color filter, manufacturing device of organic electroluminescence, and the other patterning device.
- The cleaning filling liquid may be filled in a cartridge that is used for maintenance. Structure of the cartridge may be same to the ink cartridge provided that the inkjet ink is replaced to the cleaning filling liquid. In this case,
ink cartridge 201 inFIG. 1 may be replaced to the cartridge. - Inkjet ink used in the embodiment is explained below.
- Examples of the component of the inkjet ink include a colorant, a water-soluble organic solvent, a surfactant, and the other additive such as PH adjuster, antiseptic agent, antifungal agent, antirust, water-soluble UV absorber, and water-soluble IR absorber. When the inkjet ink is dried and solid content of the inkjet ink such as colorant and resin is left, it causes jetting defect such as curving of the inkjet ink in flight. Particularly, when a pigment as the colorant or a resin emulsion as the resin is used, the solid content tends to be left and fixed, because the pigment or the resin does not dissolve but disperse in solvent. When once the resin emulsion is dried to fix, the resin emulsion can not redisperse, even if liquid for ejecting is newly supplied. In addition, the resin emulsion has adhesive performance, because the resin emulsion is used for adding adhesive property, it was very difficult to clean up the solid content, when once the resin emulsion fix to inside surface of the nozzle. However, the embodiments according to the present invention can resolve the problem.
- The colorant is selected from conventionally known pigments and dyes.
- Examples of an inorganic pigment include titanium oxide, iron oxide, calcium carbonate, barium sulfate, aluminum hydroxide, barium yellow, cadmium red, chrome yellow, carbon blacks manufactured by publicly known method such as contact method, thermal method, and furnace method. Examples of an organic pigment include azo pigments including azo lake pigment, insoluble azo pigment, condensed azo pigment, chelate azo pigment; polycyclic pigments such as phthalocyanine pigment, perylene pigment, perinone pigments, anthraquinone pigments, quinacridone pigments, dioxadine pigments, indigo pigments, thioindigo pigments, isoindolinone pigments and quinophthalone pigments; dye chelates including basic dye chelates and acidic dye chelates; nitro pigments; nitroso pigments; and aniline black. Among them the pigments having high affinity for solvent are preferred.
- Self dispersion type pigment having functional groups such as sulfone group and carboxyl group on surface thereof to be able to disperse in warter may be used. Also, pigments that are microencapsulated to be able to disperse in warter may be used.
- The amount of the pigment as the colorant in the inkjet ink is preferably 0.5% by mass to 25% by mass, more preferably 2% by mass to 15% by mass. Generally, when the inkjet ink has higher amount of the pigment, high quality printed image having higher image density may be provided, however, reliability such as fixablilty or jetting stablility may decrease.
- The particle diameter of the pigment is not particularly limited. However, the greatest frequency of the particle diameter in maximum number conversion is 20 nm to 150 nm. When the diameter is more than 150 nm, dispersion stability, jetting stability, image quality such as image density may decrease. When the diameter is less than 20 nm, storage stability and jetting stability may be obtained, but, it may not be economical, because complicate dispersion treatment or mesh control may be needed for making fine particle.
- When the pigment is dispersed by a dispersant, conventionally known dispersants such as polymer dispersant or water-soluble surfactant may be used.
- The inkjet ink may include a resin for increasing image fixing, image quality, and pigment dispersion property.
- Examples of the hydrophilic polymers as the resin include, as naturally occurring polymers, vegetable polymers such as gum acacia, tragacanth gum, guar gum, karaya gum, locust bean gum, arabinogalactan, pectin and quince seed starch; sea weed polymers such as alginic acid, carrageenan and agar; animal polymers such as gelatin, casein, albumin and collagen; and microbial polymers such as xantene gum and dextran; as semi-synthetic polymers, cellulose polymers such as methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose and carboxymethylcellulose; starch polymers such as sodium starch glycolate and sodium starch phosphate ester; and sea weed polymers such as sodium alginate and alginate propylene glycol ester; and as pure synthetic polymrers, vinyl polymers such as polyacrylic acid, polymethacrylic acid, acrylic acid-acrylonitril copolymer, vinyl acetate-acrylic acid ester copolymer, vinyl acetate-acrylic acid alkylester copolymer, styrene-acrylic acid copolymer, styrene-methacrylic acid copolymer, styrene-acrylic acid-acrylic acd alkylester copolymer, styrene-methacrylic acid-acrylic acid alkylester copolymer, styrene-α-methylstyrene-acrylic acid copolymer, acrylic acid alkylester copolymer, styrene-maleic acid copolymer, vinyl naphthalene maleic acid copolymer, vinyl acetate-ethylene copolymer, vinyl acetate-fatty acid vinyl ethylene copolymer, vinyl acetate-maleic acid ester copolymer, vinyl acetate-crotonic acid copolymer, and vinyl acetate-acrylic acid copolymer; and salt thereof.
- The amount of the resin is arbitrarily selected in consideration of reliability.
- The inkjet ink may include the resin which is not soluble to solvent but dispersible to solvent as fine particle of resin emulsion. The resin emulsion is composed of resin fine particles that are dispersed in a continuous phase of solvent. The resin emulsion may include a dispersant such as surfactant. The amount of resin fine particles as dispersion phase (the amount of the resin fine particle in the resin emulusion) is generally 10% by mass to 70% by mass. The average particle diameter of the resin fine particle is not particularly limited but preferably 10 nm to 1000 nm, more preferably 20 nm to 300 nm, when it is used in the inkjet recording apparatus.
- The fine resin particles as dispersed phase are not particularly limited and can be appropriately selected depending on the purpose. Examples thereof include acrylic resins, vinyl acetate resins, styrene resins, butadiene resins, styrene-butadiene resins, vinyl chloride resins, acrylic/styrene resins and acrylic silicone resins. Among them, the acrylic resins are preferred. The resin emulsion is used for ensuring reliability. Commercially available resin emulsion may also be used.
- Examples of the commercially available resin emulsion include Micro Gel E-100, E-2002, and E-5002 (styrene-acrylic resin emulsion, product of NIPPON PAINT Co., Ltd.), Boncoat 5454 (styrene-acrylic resin emulsion, product of Dainippon Ink and Chemicals Inc.), JONCRYL 775 (styrene-acrylic resin emulsion, product of Johnson polymer), SAE-1014 (styrene-acrylic resin emulsion, product of ZEON CORPORATION), Saibinol SK-200 (acrylic resin emulsion, product of Saiden Chemical Industry Co., Ltd.), Primal AC-22, AC-61 (acrylic resin emulsion, product of Rohm and Haas Company), NANOCRYL SBCX-2821, 3689 (acrylic silicone resin emulsion, product of TOYO INK MFG. CO. LTD.), and #3070 (methyl methacrylate polymer resin emulsion, product of Mikuni Color Ltd.).
- The amount of the resin fine particle is not particularly limited but generally 0.1% by mass to 50% by mass, preferably 0.5% by mass to 20% by mass, more preferably 1% by mass to 10% by mass.
- A water-soluble organic solvent, a surfactant, a pH adjuster, antiseptic agent, and antifungal agent, used in the inkjet ink are similar as those used in the cleaning filling liquid.
- The aforementioned inkjet ink is made by dispersing or disolving the components into solvent, and then mixing them as needed. A sand mill, a homogenizer, ball mill, a paint shaker, or an ultrasonic disperser may be used for dispersing. A general stirring device having stirrer, magnetic stirrer, or high speed disperser may be used for mixing.
- The present invention will be more specifically explained with reference to Examples and Comparative Examples, but Examples shall not be construed to as limit the scope of the present invention in any way.
