    • There are provided a resin composition that is suitable for an optical component which, while maintaining moldability, low birefringence, heat resistance, mass productivity, mechanical strength, and light transmittance, hardly exhibits a low light transmittance during the use of a blue-violet laser beam source and a deterioration in optical properties, and an optical component produced by molding the resin composition, and a optical pickup device using the optical component. The present invention provides a resin composition comprising 0.05 to 5 parts by weight of the specific hindered amine compound based on 100 parts by weight of the polymer having an alicyclic structure in at least a part of repeating structural unit, an optical component produced by molding the resin composition, and a optical pickup device using the optical component.
    • 提供了适用于光学部件的树脂组合物,其在保持成型性的同时具有低双折射性,耐热性,质量生产率,机械强度和光透射率,在使用蓝紫激光时几乎不显示低透光性 光束源和光学性质的劣化,以及通过模制树脂组合物而制造的光学部件,以及使用该光学部件的光学拾取装置。 本发明提供一种树脂组合物,其含有0.05〜5重量份的特定受阻胺化合物,相对于100重量份在至少部分重复结构单元中具有脂环结构的聚合物,通过将 树脂组合物和使用该光学部件的光学拾取装置。
