RESIN MOLDED PRODUCT, METHOD FOR PRODUCING RESIN MOLDED PRODUCT AND USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a resin molded product having excellent optical, thermal and mechanical characteristics, especially a resin molded product useful as a plastic substrate for a high-precision flexible display. SOLUTION: The resin molded product having 50-300μm thickness is obtained by photo-curing a photopolymerizable composition [I] and characterized as satisfying the following three conditions. (1) The glass transition temperature is≥200°C, (2) a flexural modulus at 30°C is 3.0-4.5 GPa, and (3) it does not break when flex resistance tests by a mandrel method using a cylindrical form having 10 mm diameter (2 s bending time and 100 mm×50 mm sample size) are carried out according to JIS K 5600-5-1:1999.
