CROSSLINKED POLYLACTIC ACID RESIN COMPOSITION FOR OPTICAL MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a polylactic acid resin composition for an optical material excellent in not only transparency but heat resistance, to provide a molded body for an optical material comprising the the resin composition, and to provide a polylactic acid resin composition for an optical material showing decrease in yellowing and a molded body for an optical material comprising the resin composition. SOLUTION: The crosslinked polylactic acid resin composition for an optical material is obtained by compounding 0.1 to 10 parts by weight of a carbodiimide compound and 0.1 to 10 parts by weight of a crosslinking monomer to 100 parts by weight of a polylactic acid resin to prepare a polylactic acid resin composition and irradiating the composition with active energy rays.
