    摘要: A polymer-encapsulated pigment dispersion is prepared from a mixture of (a) a carrier; (b) pigment particles; and (c) a polymeric dispersing agent having a polymer backbone, and a zwitterionic polymer side chain comprising anionic and cationic groups. The dispersing agent may provide efficient pigment wetting and dispersion using relatively low and thus economical pigment amounts, with good opacity and good hiding characteristics, especially in titanium dioxide-containing coating compositions

    摘要: A polymer modified pigment having a polymer (P-1) on the surface of a pigment (A), wherein the polymer (P-1) is obtained by copolymerizing a copolymer (B-1) of a polymerizable unsaturated monomer containing at least one polymerizable unsaturated group soluble in a non-aqueous solvent, and at least one kind of polymerizable unsaturated monomer (C), which is soluble in the non-aqueous solvent and either insoluble or poorly soluble following polymerization: and a polymer modified pigment having a polymer (P-2) on the surface of a pigment (A), wherein the polymer (P-2) is obtained by polymerizing at least one kind of polymerizable unsaturated monomer (C) soluble in the non-aqueous solvent and either insoluble or poorly soluble following polymerization, in the presence of an alkyd resin (B-2) soluble in a non-aqueous solvent.
