Abstract
A light-sensitive material for producing color-test films for multi-color printing is disclosed. The material has (A) a transparent flexible base film of a plastic, (B) a photopolymerizable layer containing (B1) a polymeric binder, (B2) a compound polymerizable by a free-radical mechanism, (B3) a compound capable of initiating the polymerization of (B2) under the action of actinic light, and (B4) a dye or a colored pigment in one of the basic colors of multi-color printing, and (C) a thermoplastic adhesion layer on the light-sensitive layer is described. A polymer of a vinyl alkyl ether is present in at least one of the layers (B) and (C). The material is processed by lamination to an image-receiving material, with subsequent exposure and peeling-apart of base film and image-receiving material. The unexposed layer areas remain together with the adhesion layer on the image-receiving material. These steps are repeated with at least one further part-color image. The material gives improved image resolution and has improved storage stability in the unexposed state.
