ABSTRACT:
Radiation-reactive mixtures suitable for producing insulating layers and printed circuits are composed of certain precursors for preparing polyimides, polyisoindoloquinazolinediones, polyoxiazinediones, polyquinazolinediones or polyquinazolones and aryl-containing carbonyl compounds which when excited by UV radiation are capable of hydrogen abstraction, these mixtures undergoing solubility differentiation on irradiation with actinic light.
