Abstract:
A hindered amine compound obtained by copolymerizing at least one polymerizable hindered amine monomeric compound (A3) of the formula (5): in which R is a straight or branched alkyl group having 1 to 10 carbon atoms, R3 is a hydrogen atom or methyl group, R4 is a hydrogen atom, a straight or branched alkyl group having 1 to 10 carbon atoms, or an alkoxy group having 1 to 10 carbon atoms, and X1 is a â€”Oâ€” group or a â€”NHâ€” group, and at least one polymerizable monomer (C2) of the formula (6): in which R5 is a hydrogen atom or a methyl group, R6 is a cycloalkyl group having 5 to 10 carbon atoms, and Y1 is a â€”Oâ€” group or a â€”NHâ€” group, wherein the weight percentages WA3 and WC2 of the components (A3) and (C2), respectively, satisfy the following formulas (III) and (IV): 80&lE;WA3+WC2&lE;100â€ƒâ€ƒ(III) 0.5&lE;WA3/WC2&lE;2.3â€ƒâ€ƒ(IV).
