Definitions
- the present invention relates to a method for producing an ink composition which is preferably used in an ink jet recording method, and an ink composition prepared by the method.
- pigments are generally insoluble in water

- the ink jet recording method it is necessary to increase the response frequency of the recording head in order to increase the recording speed. For that purpose, it is desirable that the ink ejection amount is small. For that purpose, it is preferable to obtain a larger dot diameter with a smaller ink ejection amount. On the other hand, however, in order to eliminate white streaks due to insufficient dot diameter, especially in solid recorded images (solid), a larger amount of ejected ink must be required.
- ink sponge for ink jet recording has generally been carried out by dispersing a pigment together with a dispersant to obtain a pigment dispersion and adding various components thereto.
- the present inventors have now found that, in the production of a pigment-based ink composition, the characteristics of the ink pirates vary depending on the order of the added components. Then, they have found that by dispersing the specific component together with the pigment, an ink composition that can reduce the bleeding on the recording medium and can realize a large dot diameter with a further smaller ejection ink amount can be produced.
- the present invention is based on this finding. Therefore, the present invention provides a method for producing an ink composition for ink jet recording, which has less bleeding on a recording medium and can increase the dot diameter with a smaller amount of ejected ink, and further provides an ink composition prepared by such a production method Its purpose is to provide
