STRAHLUNGSEMPFINDLICHES GEMISCH.

摘要

Radiation-sensitive mixt. is based on a cpd. (I) forming a strong acid when exposed to actinic radiation and a polymer (II) with recurring, acid-hydrolysable acetal or ketal gps. The novelty is that (II) is a reaction prod. of an organic polymer (III) with free OH gps., an organic cpd. (IV) with at least 2 NCO or epoxy gps. and a cpd. (V) with recurring, acid-hydrolysable acetal or ketal gps. and at least one free OH gp.
