摘要：
A plastic mold is produced by first repeating the process of forming a layer of a photocurable resin composition of a specified kind and exposing it to actinic radiation to at least partially photocure it to produce a photocured layered structure having a glass transition temperature of 70.degree.-120.degree. C. This structure is then subjected to a post-cure process at a temperature high than the glass transition temperature by 30.degree.-100.degree. C. Plastic molds made by this method have superior heat distortion temperature and tensile elastic modulus.
