ABSTRACT:
2-Substituted malondialdehyde compounds are useful as co-developers in combination with hindered phenol developers to produce 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.
