Radiation-sensitive compositions and their use.

摘要

The invention relates to radiation-sensitive mixtures of certain precursors and carbonyl compounds which contain aromatic radicals and, in the UV-excited state, are capable of hydrogen abstraction, which mixtures experience a solubility differentiation on irradiation with actinic light and are suitable for the preparation of polyimides, polyisoindoloquinazolinediones, polyoxazinediones, polyquinazolinediones or polyquinazolones. They are suitable for the production of insulating layers and printed circuit boards.
