ACTIVE ENERGY BEAM-CURABLE RESIN COMPOSITION, RESIN MOLDED ARTICLES, AND METHOD FOR PRODUCING RESIN MOLDED ARTICLES

摘要

This active energy beam-curable resin composition contains: (A) a urethane poly(meth)acrylate synthesized from raw materials including a polyisocyanate and a hydroxy group-containing (meth)acrylate; (B) a (meth)acrylate having five or more functional groups; (C1) a photoinitiator having an extinction coefficient in a methanol solution of not less than 50,000 ml/g·cm at 254 nm; (C2) a photoinitiator other than (C1) having an extinction coefficient in a methanol solution of not less than 50,000 ml/g·cm at 302 nm; (C3) a photoinitiator other than (C1) and (C2) having an extinction coefficient in a methanol solution of not less than 100 ml/g·cm at 405 nm; and (D) an ultraviolet absorber.
