摘要:
A display such as meter panel and advertising display comprises a color image forming layer provided on a light-transmitting permanent support via a photo-polymerizable adhesive layer, and a photo-polymerizable image-receiving layer closely adhered to the color image forming layer. The display can be effectively produced by a process comprising the steps of forming a color image on a photo-polymerizable image-receiving layer of a photosensitive image-receiving material, placing it upon a photo-polymerizable adhesive layer formed on a light-transmitting permanent support to form a laminate so that the photo-polymerizable image-receiving layer and the photo-polymerizable adhesive layer face each other and then exposing the laminate to light so as to closely adhere the photo-polymerizable image-receiving layer and the photo-polymerizable adhesive layer to their adjacent layers, respectively, by the photo-polymerization. By this method, the adhesion between the photo-polymerizable image-receiving layer and the light-transmitting permanent support is improved.
