Document Type and Number:
Japanese Patent JP4114805
Kind Code:
B2
Abstract:
The present invention provides a pigment dispersion composition which has good fluidity and dispersion stability even in the case of having a high pigment concentration and exhibits excellent development characteristics when it is used for the areas requiring development characteristics such as a resist composition for a color filter or a resist composition for a black matrix. The pigment dispersion composition of the present invention is a pigment dispersion composition formed by dispersing a pigment in a dispersion medium, wherein the surface of said pigment is coated with an acid radical-containing reactant produced by the reaction of a carbodiimide compound having at least one carbodiimide group with an acid radical-containing resin having an acid value of 20 to 300 mgKOH/g and a weight average molecular weight of 1000 to 100000.
