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.
丙烯腈化合物与受阻
酚显影剂组合使用时,可用作共显影剂,以产生高对比度的黑白光热和热敏元素。
丙烯腈化合物与(i)受阻
酚显影剂,以及(ii)三苯甲基
肼和/或甲酰苯
肼共显影剂组合使用时,也可用作共显影剂,以产生超高对比度的黑白光热和热敏元素。这些光热和热敏元素可用作光掩模,用于在随后的紫外线或短波长可见光辐射敏感的可成像介质中曝光的过程中。
