NONAQUEOUS PIGMENT DISPERSION COMPOSITION

WIPO Patent Application WO/2010/125979

A1

Disclosed is a nonaqueous pigment dispersion composition which contains a pigment (A), a nonaqueous solvent (B) and a graft polymer (C) that contains the main chain and the side chain described below, said graft polymer (C) being obtained by a coupling reaction of the main chain and the side chain. The nonaqueous pigment dispersion composition has low viscosity, excellent handling properties, excellent coatability and excellent dispersion stability. Also disclosed is a method for producing the graft polymer (C) for dispersing a nonaqueous pigment. Main chain: a copolymer which contains a constitutional unit derived from a vinyl monomer (a) containing a nitrogen atom and a constitutional unit derived from a vinyl monomer (d) containing a reactive functional group Side chain: a copolymer which contains a constitutional unit derived from a (meth)acrylate ester (b) containing a benzene ring, and has a functional group at one end, said functional group being reactive with the reactive functional group of the main chain
