Positive-working photosensitive composition containing a dye and positive-working photosensitive recording material prepared therefrom

Claim 1

Positive-working photosensitive composition comprising, in admixture: a positive-working photosensitive compound in an amount sufficient to render exposed areas soluble in a developer, said compound being selected from the group consisting of (1) an o-quinone diazide and (2) a combination of photolytic acid donor with an acid-cleavable compound, a binder that is isoluble in water and soluble or swellable in an aqueous-alkaline solution, present in an amount such that said composition forms a uniform film when applied to a substrate, and a dye comprising a non-bleachable compound that absorbs light in the region of actinic radiation to which the photosensitive compound responds and corresponds to the general formula I ##STR3## wherein R 1 denotes hydrogen, alkyl, aryl, alkoxy or nitrilo, R 2 and R 3 are identical or different and denote hydrogen, hydroxy, alkyl, aryl, alkoxy, aryloxy, nitrilo, amino, alkylamino or halogen, and R 4 , R 5 , R 6 and R 7 are identical or different and denote hydrogen, hydroxy, alkyl, aryl, alkoxy, aryloxy, amino, alkylamino or halogen wherein said dye is present in an amount sufficient to significantly reduce the effects of reflection when said composition is coated on a substrate and exposed.
