Colored positive-working quinone diazide photosensitive recording material for the production of a color test image utilizing adhesive layer containing alkali-insoluble organic polymer and alkali-soluble polyester

A positive-working colored photosensitive recording material for the production of a color test image comprising:

• (a) a temporary layer carrier,
• (b) a release layer comprising polyvinyl alcohol on the surface of said temporary layer carrier,
• (c) a photosensitive layer, with a layer weight of about 0.5-5.0 g/m.sup.2, said layer comprising, in an admixture;
• (i) a dyestuff or pigment,
• (ii) a binder in an amount of about 20-75 weight percent based on the non-volatile contents of said photosensitive layer, said binder comprising a novolak-free phenolic polymer resin, a reaction product of said phenolic polymer resin with a monoisocyanate or a mixture thereof, and
• (iii) an esterification product of a compound containing at least one phenolic hydroxyl group and o-quinonediazide-4-sulfonyl chloride, said esterification product being present in an amount of about 10-30 weight percent based on the nonvolatile constituents of said photosensitive layer, and
• (d) an adhesive layer activatable by means of heat which comprises an alkali-insoluble organic polymer and an alkali-soluble polyester, wherein said alkali-insoluble organic polymer is present in about 70-99 weight percent and said alkali-soluble polyester is present in about 1-30 weight percent in said adhesive layer.
