Specific examples of the HALS compound include 2-2-hydroxy-3-t-butyl-5-methylphenyl-5-chlorobenzotriazole and the like. The content of the ultraviolet stabilizer is in the range of 0.1 to 0.2 parts by weight based on 100 parts by weight of the base resin. When the content exceeds 0.2 parts by weight, there arises a problem that the production cost is increased without increasing the effect.

내염소성 첨가제로는 N-O-R(R은 알킬기)계 화합물을 사용할 수 있으며, 그 구체적인 예로서는 폴리베타하이드록실에틸-2-2,6,6-테트라메틸-4-하이드록실피페리딜쑥시네이트 등을 들 수 있다. 상기 내염소성 첨가제의 함량은 기본 수지 100 중량부 대비 0.05∼3 중량부의 범위가 되도록 한다. 상기 함량이 3 중량부를 초과하는 경우 효과의 상승없이 제조비용이 높아지는 문제점이 발생한다.
NOR (R is an alkyl group) -based compound can be used as the chlorine-containing additive. Specific examples thereof include polybetahydroxylethyl-2-2,6,6-tetramethyl-4-hydroxylpiperidylsulfate, . The content of the chlorine-containing additive is in the range of 0.05 to 3 parts by weight based on 100 parts by weight of the base resin. When the content exceeds 3 parts by weight, there arises a problem that the production cost is increased without increasing the effect.
