BLACK-AND-WHITE PHOTOTHERMOGRAPHIC AND THERMOGRAPHIC ELEMENTS COMPRISING N-ACYL-HYDRAZINE COMPOUNDS AS CONTRAST ENHANCERS

N-acyl-hydrazine compounds are useful as contrast enhancers when used in combination with (i) hindered phenol developers, and (ii) trityl hydrazide and/or formyl-phenyl hydrazine co-developers, to produce ultra-high contrast black-and-white photothermographic and thermographic elements. The photothe...

Zusammenfassung:	N-acyl-hydrazine compounds are useful as contrast enhancers when used in combination with (i) hindered phenol developers, and (ii) trityl hydrazide and/or formyl-phenyl hydrazine co-developers, to produce ultra-high contrast black-and-white photothermographic and thermographic elements. The photothermographic and thermographic elements may be used as a photomask in a process where there is a subsequent exposure of an ultraviolet or short wavelength visible radiation-sensitive imageable medium. L'invention porte sur des composés N-acyl-hydrazine utilisés comme renforçateurs de contraste en combinaison avec (i) des agents de développement phénoliques inhibés, et (ii) des co-agents de développement trityl hydrazide et/ou formyl-phényl hydrazine, pour produire des éléments thermographiques et photothermographiques noir et blanc à contraste très accentué. Les éléments thermographiques et photothermographiques peuvent être utilisés comme photomasques au cours d'un processus d'exposition complémentaire d'un milieu imageable sensible à des rayons visibles à courte longueur d'onde ou ultraviolets.
