摘要： PROBLEM TO BE SOLVED: To obtain enough surface scratching resistance and wear resistance by forming a temporarily hardened layer in coating and temporary hardening processes, applying a specified compsn. to constitute the outermost layer of a transparent coating layer, irradiating the layers with active energy rays to completely harden the whole temporarily hardened layers and the compsn. SOLUTION: The transparent coating layer consists of at least two layers of a transparent layer adjacent to the surface of a base body and a transparent layer as the outermost layer. The transparent coating layer is produced in the following process. First, a compsn. (A) is applied on the surface of a transparent plastic base body and irradiated with active energy rays to partially harden. This temporary hardening process is carried out once or more times to form temporarily hardened layers. Then the compsn. (A) as the outermost layer is applied. Then active energy rays are made to irradiate to completely harden the temporarily hardened layers and the compsn. (A) of the outermost layer. The compsn. (A) contains a polymn. initiator and a polyfunctional compd. having two or more polymerizable functional groups which are hardened with active energy rays. As for the material of the transparent plastic base body, especially an aromatic polycarbonate resin planer sheet is preferable.
