Existing coloring compositions do not have a practical range of elution resistance. Therefore, an object of the present invention is to provide a coloring composition having better elution resistance (less dye elution) than conventional coloring compositions. The present invention relates to a compound represented by the following general formula (1), a coloring composition containing 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, etc., Y1 and Y2 independently represent -O-, etc., A1 represents a specific alkylene group, etc., A 2 represents an alkylene group that may have -O- in the chain and a group represented by the following general formula (2) in the chain or at the end, n represents 1 or 2; (in the formula, R 1 and Y 2 are the same as the The same as above, R 3 represents the group represented by the following general formula (2-1), etc., A 3 represents a specific alkylene group, etc.; [wherein, R 1 , A 3 and Y 2 are the same as described]) }. |
