The invention relates to a radiation-sensitive material comprising A) a multilayer support material, B) a colored photopolymerizable layer, and C) an adhesive layer. The multilayer support material consists of at least two sheet-form materials, which are bonded to one another in such a way that the adhesion between the two sheet-form materials is less than the adhesion between the radiation-sensitive layer and the adjacent support material. The invention furthermore relates to a process in which a colored image, in particular a multicolored image comprising a plurality of primary-color images, is produced on an image-receiving material. The color images are produced by laminating a colored photopolymerizable layer onto the image-receiving material, exposing the material under the relevant master, in particular a color separation, developing the image by peeling-off the support film from the photopolymerizable layer together with the non-image areas, and, if desired, repeating the same steps with a photopolymerizable layer in a different color.

The invention relates to a positive-working colored photosensitive recording material for the production of a color test image, composed of a temporary layer carrier, a photosensitive layer containing dyestuff or pigment, binder and quinonediazide compound and an adhesive layer which can be activated by means of heat, wherein a release layer based on polyvinyl alcohol is present on the surface of the temporary layer carrier, the photosensitive layer comprises, as the quinonediazide compound, an esterification product of a compound containing one or more phenolic hydroxyl groups and o-quinonediazide-sulfonyl chloride, and, as the binder, a novolak-free phenolic polymer resin and/or a reaction product of the phenolic polymer resin with a monoisocyanate, and the adhesive layer comprises a alkali-insoluble organic polymer and an alkali-soluble polyester. The invention also relates to a process for the production of a color test image using the recording material described.
