ABSTRACT:
Acrylonitrile compounds are useful as co-developers when used in combination with hindered phenol developers to produce high contrast black-and-white photothermographic and thermographic elements.
Acrylonitrile compounds are also useful as co-developers when used in combination with (i) hindered phenol developers, and (ii) trityl hydrazide and/or formyl-phenyl hydrazinc 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.
