Abstract:
1. A polymer modified pigment particle having a polymer (P-1) on the surface of a pigment (A), wherein the polymer (P-1) is obtained by copolymerizing in a non-aqueous solvent, a copolymer (B-1) and at least one kind of polymerizable unsaturated monomer (C); and the copolymer (B-1) comprises at least one polymerizable unsaturated group, is obtained by polymerization of a polymerizable unsaturated monomer, and is soluble in a non-aqueous solvent; and at least one kind of polymerizable unsaturated monomer (C) is soluble in the non-aqueous solvent and either insoluble or poorly soluble following polymerization, and includes a polyfunctional polymerizable unsaturated monomer.
