<P>PROBLEM TO BE SOLVED: To provide a pigment fine particle dispersion, in which a particle size of the fine particle is small and a peak of particle distribution is sharp, that is particularly suitable to a color material for a color filter, enhances its contrast and light resistance, and exhibits good dispersibility. <P>SOLUTION: This pigment fine particle dispersion includes pigment fine particles and a compound represented by formula (1) (wherein, Q is an organic coloring matter residue with an aromatic ring; A<SP>1</SP>is alkylene, arylene or heteroarylene which may have a substituent; Z is an acidic group expressed by SO<SB>3</SB>H or CO<SB>2</SB>H; R<SP>1</SP>and R<SP>2</SP>are a predetermined substituent; L<SP>1</SP>is a single bond or a divalent organic linking group; P is an aryl group which may have a substituent, or an atomic group required to form a group with which at least two aryl groups which may have a substituent are linked; m is an integer of 0 or 1; and n is an integer of 1-4). <P>COPYRIGHT: (C)2011,JPO&INPIT |
