  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. (wherein R 1 to R 4 each independently represent a hydrogen atom, an alkyl group, and the like; R 7 represents a hydrogen atom or a methyl group; R 8 and R 9 each independently represent a hydrogen atom or an alkyl group; Y represents a nitrogen atom or a group represented by the following formula (1-1): A 1 represents an alkylene group which has at least one group selected from —O—, —OCO—, —COO—, —NHCO—, —CONH—, —NHCONH— and an arylene group in the chain, and the like; A 2 represents —NH— or —O—; An − represents an anion containing an aryl group having an electron-withdrawing substituent, and the like; n represents an integer of 0 to 3; R 8 and R 9 may form a cyclic structure of a 5 to 6 membered ring together with —N—(CH 2 ) n —Y— bonding thereto.)
