Abstract
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 compresses 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.
