Abstract

Provided is a cationized silica dispersion prepared by dispersing dry processed silica and a cationic resin in a polar solvent, wherein a concentration of dissolved silicic acid at 25°C is 200 ppm or less. This cationized silica dispersion does not substantially form coagulated matters when blended with a binder and therefore can advantageously be used for producing a coating composition such as a coating composition for forming a gas barrier layer, a corrosion preventive coating composition and a coating composition for ink jet recording paper.

Claims (7)

1. A cationized silica dispersion prepared by dispersing dry processed silica and a cationic resin in a polar solvent, wherein a concentration of dissolved silicic acid at 25°C contained in the above dispersion is 200 ppm or less in terms of SiO2.
2. The cationized silica dispersion as described in claim 1, wherein the dry processed silica has a specific surface area of 50 m2/g or more which is determined by a BET method.
3. The cationized silica dispersion as described in claim 1, wherein a light scattering index is 2:0 or more.
4. A production process for a cationized silica dispersion, characterized by that in dispersing dry processed silica and a cationic resin in a polar solvent to produce a cationized silica dispersion, a concentration of dissolved silicic acid contained in the cationized silica dispersion at 25°C is measured and controlled to 200 ppm or less in terms of SiO2.
5. The production process for a cationized silica dispersion as described in claim 4, wherein the above cationized silica dispersion is brought into contact with an anion exchange resin to thereby control the dissolved silicic acid concentration.
6. A production process for a coating composition, characterized by comprising a dispersing step for dispersing dry processed silica and a cationic resin in a polar solvent to obtain a cationized silica dispersion and a binder blending step for blending the cationized silica dispersion obtained at the above dispersing step with a binder, wherein a dissolved silicic acid concentration-controlling step for controlling a concentration of dissolved silicic acid at 25°C contained in the cationized silica dispersion to 200 ppm or less in terms of SiO2 is further interposed between the dispersing step and the binder blending step each described above.
7. The production process for a production process for a coating composition as described in claim 6, wherein the above cationized silica dispersion is brought into contact with an anion exchange resin to thereby control the dissolved silicic acid concentration.
