| abstract |
A resin composition includes an alicyclic structure-containing polymer; a hindered amine compound; and a releasing agent, wherein the releasing agent and the alicyclic structure-containing polymer satisfy the following relationship: 10≧|s1−s2|≧0.8 [(MPa) 0.5 ], wherein s1 represents a solubility parameter of the releasing agent, and s2 represents a solubility parameter of the alicyclic structure-containing polymer. The resin composition can be used as optical materials, such as a lens, a diffraction grating, and a prism, especially in the field of using blue laser, and has excellent releasability, transparence and colorless property as well as excellent resistance to laser. |
