A plastic optical article wherein a transparent coating film is applied onto a transparent three-dimensional crosslinked resin having a glass transition temperature of 130 ° C. or higher. The product has excellent heat resistance, solvent resistance, chemical resistance, abrasion resistance and transparency, and the product is used as an optical material for optical lenses and a substrate for various display devices. In addition, when deposited on a thin layer inorganic film such as a transparent electrically-conductive film, a thin layer film excellent in heat resistance can be obtained. |
