PROBLEM TO BE SOLVED: To provide a method for dramatically improving the weather resistance of a synthetic resin, specifically, a method for improving the appearance maintenance property, gloss retention property, acid rain resistance and the like of the synthetic resin. . SOLUTION: An N-carbamoyloxy-2,2,6,6-tetramethylpiperidine structure is contained in 100 parts by weight of a synthetic resin (A), and the structural formula is represented by the general formula (I) and / or (I) At least one of the compounds (B) having the structure represented by I) Is a synthetic resin composition obtained by adding 0.001 to 20 parts by weight of Embedded image (In the formula (I), X is -OCO-, -NHCO- or -OC Represents ONH—, R 1 and R 2 are divalent groups, each independently having a saturated or unsaturated aliphatic hydrocarbon group having 1 to 20 carbon atoms, an aliphatic hydrocarbon group having an ether bond, and an aromatic group. Represents an aromatic group or an aromatic group having a substituent, and n represents an integer of 2 or more. ) (In the formula (II), R 2 and n are the same as those in the formula (I).) |
