Process for the production of a multicolored image and photosensitive material for carrying out this process

Abstract

The invention relates to a photosensitive material for the production of color proofing films for multicolor printing comprising: A) a transparent, flexible film support, B) a photopolymerizable layer containing: B1) a polymeric binder, B2) a free radical-polymerizable compound, B3) a compound which is capable of initiating the polymerization of (B2) on exposure to actinic light, and B4) a dye or colored pigment in a primary color of multicolor printing, and C) a thermoplastic adhesive layer on the photosensitive layer, which contains at least about 1.5% by weight of a water-soluble, colorless, low-molecular-weight salt whose aqueous solution is not highly acidic. The material is processed by lamination onto an image-receiving material, exposure and peeling apart of the film support and the image-receiving material, the unexposed areas of the layer and the adhesive layer remaining on the image-receiving material. The addition of the salt to the adhesive layer substantially reduces the adhesion between this layer and the exposed areas of the photopolymerizable layer.
