Patent attributes
It is an object of the present invention to provide a transparent resin molding having both high reflow heat resistance and excellent optical characteristics and to provide an optical lens and an optical film each including the transparent resin molding and having high heat resistance and excellent optical characteristics. A transparent resin molding according to the present invention is obtained by molding a molding material containing a thermoplastic resin and crosslinking the thermoplastic resin, in which the thermoplastic resin is selected from resins having an average transmissivity of 60% or more in the wavelength range of 600 to 1,000 nm when molded into a molding with a thickness of 2 mm, and the resin molding with a thickness of 2 mm has an average transmissivity of 60% or more in the wavelength range of 600 to 1,000 nm when the resin molding is heated at 200° C. for 10 minutes.
