PIPERIDINE DERIVATIVE OR SALT THEREOF, RESIN COMPOSITION, AND MOLDED ARTICLE PRODUCED FROM THE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a resin composition capable of obtaining a molded article excellent in optical characteristics such as light resistance, a molded article such as optical component obtained by molding the resin composition, and an optical pickup device using the optical component.SOLUTION: A resin composition includes: 100 pts.mass of a polymer having an alicyclic structure in at least a part of a repeating unit; and 0.05-5 pts.mass of a hindered amine compound wherein a ratio of a carbon atom inside the molecular structure is 67-80 wt.% and a molecular weight is 500-3,500. A novel piperidine derivative having a piperidylaminotriazine skeleton; a molded article such as an optical component produced by molding the resin composition; and an optical pickup device using the optical component are also provided.
