Abstract: The present invention is to provide a colored composition having higher heat resistance compared with conventional colored compositions. The present invention further relates to: “a polymer having a monomer unit derived from a monomer which has (i) a cationic rhodamine derivative having, as an counter anion, an anion including an aryl group having an electron-withdrawing substituent and an anion group and (ii) an ethylenically unsaturated bond”, “a monomer which has (i) a cationic rhodamine derivative having, as an counter anion, an anion including an aryl group having an electron-withdrawing substituent and an anion group and (ii) an ethylenically unsaturated bond”, “a colored composition comprising the above-described polymer or the monomer”, and “a colored composition for a color filter comprising the above-described polymer or the monomer”.

Abstract: It is an object of the present invention to provide a cyanine-based coloring composition having higher heat resistance, as compared with a conventional coloring composition. The present invention relates to a compound represented by the following general formula (1), a polymer having a monomer unit derived from the compound, along with a coloring composition, a coloring composition for a color filter, and a colored resin comprising the above-described compound or the above-described polymer.

Abstract: A coloring composition having higher heat resistance as compared with the conventional coloring composition, including a compound represented by general formula (1), and a polymer having a monomer unit derived from the compound. (wherein R1 to R4 each independently represent a hydrogen atom, an alkyl group; R7 represents a hydrogen atom or a methyl group; R8 and R9 each independently represent a hydrogen atom or an alkyl group; Y represents a nitrogen atom or a group represented by formula (1-1): A1 represents an alkylene group having at least one group selected from —O—, —OCO—, —COO—, —NHCO—, —CONH—, —NHCONH— and an arylene group in the chain; A2 represents —NH— or —O—; An ?represents an anion containing an aryl group having an electron-withdrawing substituent; n represents an integer of 0 to 3; R8 and R9 may form a cyclic structure of a 5 to 6 membered ring together with —N—(CH2)n—Y— bonding thereto.

Abstract: A colored resin composition using a conventional rhodamine derivative has not provided heat resistance in a practical range. Therefore, it is an object of the present invention to provide a coloring composition having higher heat resistance as compared with the conventional coloring composition. The present invention relates to a compound represented by the following general formula (1), and a polymer having a monomer unit derived from the compound, and the like.
