<P>PROBLEM TO BE SOLVED: To provide a colored curable composition with which a cured film excellent in light resistance, heat resistance, and solvent resistance is formed, a color filter, a solid-state imaging element, a liquid crystal display, and an organic EL display, as well as a metal chelate pigment. <P>SOLUTION: The coloree curable composition includes a polymerizable compound, a polymerization initiator, and a metal chelate pigment which satisfies at least three of (1)-(4). (1) An acid dissociation constant (25°C) of either an acid group when a pigment ligand has an acid group, or a protonic acid corresponding to a counter anion other than the pigment ligand is less than 3. (2) The pigment ligand has at least two or more branched-chain substituents. (3) When the pigment ligand is configured of a hydrocarbon aromatic ring or a heteroaromatic ring, the number of α hydrogens of the hydrocarbon group is one or less per one substituent, or when the pigment ligand includes an alkylene group other than a methacryloyl group, there is no hydrogen at an allyl position. (4) The pigment ligand has a fading preventing group in an atomic group which constitutes it. <P>COPYRIGHT: (C)2012,JPO&INPIT |
