schwarzweisse photothermographische and thermographische elements, 4 - substituted isoxazolverbindungen as hilfsentwickler contain

摘要

4-Substituted isoxazole 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.
