Claims
- 1. A polyvinyl chloride resin composition having blended therein a hindered amine light stabilizer selected from the group consisting of a polycondensate of dimethyl succinate and 1-(2-hydroxyethyl)-4-hydroxy-2,2,6,6-tetramethylpiperidine, 1-[2-[3-(3,5-di-t-butyl-4-hydroxyphenyl)propionyloxy]-ethyl]-4-[3-(3,5-di-t-butyl-4-hydroxyphenyl)propionyloxy]-2,2,6,6-tetramethylpiperidine, and 8-acetyl-3-dodecyl-7,7,9,9-tetramethyl-1,3,8-triazaspyro[4,5]decane-2,4-dion in an amount of 0.01-5 parts by weight based on 100 parts by weight of the polyvinyl chloride resin.
- 2. A polyvinyl chloride resin composition for powder molding characterized in that there is blended therein a hindered amine light stabilizer selected from the group consisting of a polycondensate of dimethyl succinate and 1-(2-hydroxyethyl)-4-hydroxy-2,2,6,6-tetramethylpiperidine, 1-[2-[3-(3,5-di-t-butyl-4-hydroxyphenyl)propionyloxy]-ethyl]-4-[3-(3,5-di-t-butyl-4-hydroxyphenyl)propionyloxy]-2,2,6,6-tetramethylpiperidine, and 8-acetyl-3-dodecyl-7,7,9,9-tetramethyl-1,3,8-triazaspyro[4,5]decane-2,4-dion, said hindered amine light stabilizer having a melting point or softening point of not higher than 120.degree. C. and wherein said hindered light stabilizer is present in an amount of 0.01-5 parts by weight based on 100 parts by weight of the polyvinyl chloride resin.
