Radiation-curable composition and radiation-sensitive recording material for high-energy radiation prepared therefrom.

摘要

A radiation-curable mixture is proposed which contains a compound which forms an acid when exposed to high-energy radiation and a compound which is acid-cleavable, and which is characterised in that the compound which forms an acid contains aliphatically bound halogen (chlorine or bromine) and has a pKa of less than 12 or is a derivative of a compound having such a pKa, which derivative can be converted into the free compound by acid catalysis. The composition claimed, and in particular the recording material prepared therefrom, has a higher sensitivity and an improved resolution, and in addition exhibits no image haze after development.
