摘要： With a colored composition of the related art, elution resistance within a practical range is not obtained. Therefore, an object of the present invention is to provide a colored composition having better elution resistance (less dye elution) than that of the colored composition of the related art.The present invention relates to a compound represented by the following general formula (1), a colored composition comprising the compound, and the like. {In the formula, Dye represents a dye residue, R1 represents a hydrogen atom or a methyl group, Y0 represents a single bond or the like, Y1 and Y2 each independently represent —O— or the like, A1 represents a specific alkylene group or the like, A2 represents an alkylene group which may have —O— in a chain and has a group represented by the following general formula (2) in the chain or on the terminal of the chain, and n represents 1 or 2; (in the formula, R1 and Y2 are the same as described above, R3 represents a group represented by the following general formula (2-1) or the like, and A3 represents a specific alkylene group or the like; [in the formula, R1, A3, and Y2 are the same as described above.].).}
