| abstract |
A photosensitive composition comprising a photooxidant, leuco dye and a substituted hydroxylamine compound of the formula R 1 R 2 NOH wherein R 1 and R 2 , e.g., are alkyl, cyclic alkyl, aryl, aralkyl, alkaryl and R 1 and R 2 taken together form a heterocyclic ring of 5 to 7 carbon atoms. Optionally monomers and polymeric binders can be present. The compositions are useful for photoimaging and in solvent and aqueous developable resist-forming films. |
