METHOD FOR PRODUCING POLYCARBONATE ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a polycarbonate article in which a cured resin layer having required performance is formed by electron beam irradiation on the surface of a substrate using a polycarbonate-based resin as a material and deterioration of the substrate is suppressed. SOLUTION: The method for producing the polycarbonate article comprises providing an uncured resin layer composed of an electron beam-curing type resin composition on the surface of the substrate using the polycarbonate-based resin as the material, then curing the uncured resin layer and forming a cured resin layer by irradiating the uncured resin layer with electron beam and keeping the substrate so that the difference between peak temperature of loss tangent (tanδ) in dynamic viscoelasticity method of the substrate after irradiation with electron beam and that of the substrate before irradiation is≤1°C (when vibration is given by a frequency which is 20 Hz sine wave).
