Patent ID: 8329787

Claim:
A synthetic resin composition, comprising 100 parts by weight of a synthetic resin, and 0.01 to 10 parts of a hindered amine compound represented by formula (I) or (II): wherein, R in formula (I) is vinyl, allyl, butenyl, pentenyl or oleyl; and wherein when n=1, R 1 is an alkyl group having 1-22 carbon atoms, an alkenyl group having 2-22 carbon atoms, or the group represented by formula (III): wherein R in formula (III) is an alkyl group or a hydroxyalkyl group having 10-30 carbon atoms, or an alkenyl group having 2-30 carbon atoms, and wherein when n=2-6, R 1 is an organic group having 2-20 carbon atoms of valency n; wherein R in formula (II) is vinyl, allyl, butenyl, pentenyl, or oleyl, R 2 is a hydrogen atom, an alkyl group having 1-22 carbon atoms or an alkenyl group having 2-22 carbon atoms, A is a single bond, a linear- or branched-alkylene group having 1-12 carbon atoms, or an alkylene group with an ether linkage, n is an integer from 2-6, and X is —C(═O)—, a linear- or branched-alkylene group having 4-40 carbon atoms with a terminal —C(═O)O— group, a linear- or branched-alkylene group having 4-40 carbon atoms with a carboxylic acid ester linkage, or an organic group having 6-30 carbon atoms with 3-6 terminal —O—C(═O)—) groups.
