The present invention relates to a red color resist ink that gives high levels of brightness and saturation when used in color filters for liquid crystal displays.n n n As a red color resist ink formed by dispersing a red pigment in a photosensitive resin composition, using a DKPP pigment (D) and a DKPP pigment (A) surface-treated with DKPPS (E) or DKPPS as a pigment component, and dispersing this pigment component As a dispersing agent, a polyester having (i) a free carboxylic acid group, (ii) a polyamide or (iii) a polyesteramide is reacted with (a) poly (lower alkyleneimine) or (b) polyallylamine. A graft polymer (B) formed by forming a salt is used, and a sulfonic acid derivative (C) of an organic pigment is used as a crystal growth inhibitor. |
