<P>PROBLEM TO BE SOLVED: To provide a colored curable resin composition satisfying both of wet spreadability of a coloring ink and reduction of film defects in pixels, which are liable to have the relation of trade-off so far in the formation of pixels of a color filter by an ink-jet method. <P>SOLUTION: The colored curable resin composition for a color filter by an ink-jet method comprises at least a pigment, a dispersant, a binder resin and an organic solvent, wherein the dispersant is an A-B block copolymer and/or an A-B-A block copolymer comprising B blocks having an amino group in a side chain and A blocks having no amino group, the copolymer having an amine value of ≥20 mgKOH/g in terms of available solid content, and the binder resin has a weight average molecular weight of 4,000-50,000 in terms of polystyrene as measured by GPC and has an acid value of ≤150 mgKOH/g. Uses of the colored curable resin composition are also provided. <P>COPYRIGHT: (C)2010,JPO&INPIT |
