(57) Abstract: Provided is a polymer compound containing a novel 2,2,6,6-tetramethylpiperidine derivative-bonded monomer unit which is useful as an agent for preventing deterioration of a dye or dye and fading. A polymer compound containing at least a monomer unit represented by the following general formula (A) or (B). Embedded image In the formula, R 11 and R 21 represent a hydrogen atom, an oxy radical group, an alkyl group, an alkenyl group, an alkoxy group, or an acyl group, and R 12 and R 22 represent a hydrogen atom or an alkyl group. Y 1 and Y 2 are ← CONR 4 −, ← COO− or ← C H (OH) CH 2 O- and represents, X - is chloride, bromide, Z represents an iodine ion and a hydroxyl ion, and Z represents an atomic group necessary for forming a 5- to 7-membered heterocyclic ring together with a nitrogen atom. R 13 and R 23 represent a hydrogen atom, a methyl group, an ethyl group, or a halogen atom. R 4 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms. Here, ← represents a bond on the polymer main chain side. |
