ABSTRACT:
Esters of trihydric or tetrahydric alcohols with alkenylphosphonic or -phosphinic acids, which can be polymerized by means of actinic light, are disclosed. They are combined with polymeric binders, in particular water-soluble polymers, and free-radical-forming photoinitiators to form photopolymerizable mixtures which are suitable for the preparation of photoresists and the production of printing plates. The mixtures show reduced temperature sensitivity and have long shelf lives.
