PROBLEM TO BE SOLVED: To obtain an economical film or sheet which has a high adhesion to a silver plating layer, and has a good silver layer without using an etchant having a high degree of risk. SOLUTION: A processing layer coated with a composition containing a urethane-modified saturated polyester resin is provided on the surface of the plastic film or sheet. A silver layer is produced on the processing layer by a silver mirror reaction, by which the film or sheet having the good silver layer can be obtained. Further, a preprocessing layer coated with a composition containing a saturated polyester resin is provided on the surface of the plastic film or sheet, and the processing layer of the urethane-modified saturated polyester resin is formed on the preprocessing layer. A silver layer is formed on the processing layer by the silver mirror reaction, by which the film or sheet having the good silver layer can be obtained. COPYRIGHT: (C)2007,JPO&INPIT |
