POLYURETHANE RESIN ADHESION PIGMENT, PIGMENT DISPERSION COMPOSITION AND INKJET INK COMPOSITION |
摘要 |
A pigment that exhibits excellent image density, dispersibility, storage stability, and resolubility, and forms an ink film that exhibits marker resistance and rubfastness is provided. A polyurethane resin-bonded pigment is produced by bringing (I) a pigment having a surface acidic group into contact with (II) a water-dispersible polyurethane resin having a tertiary amino group and an anionic polar group or a nonionic polar chain in an aqueous medium. The pigment (I) is preferably self-dispersible carbon black having a surface acidic group. |
