Abstract

A radiation-polymerizable mixture, recording material and process for using the recording material in relief recordings. The radiation-polymerizable mixture contains: PA0 (a) a polymeric binder, PA0 (b) a compound of the formula: ##STR1## `in which A is O, NH or N-alkyl, PA1 Q is --CO--C.sub.p H.sub.2p -Z-- or --C.sub.k H.sub.2k O--, PA1 Z is O or NH, PA1 R.sup.1 is H or alkyl, PA1 R.sup.2 is alkyl, alkenyl, cycloalkyl, aryl, aralkyl or SO.sub.2 R.sup.3, PA1 R.sup.3 is alkyl, alkenyl, cycloalkyl, aryl, aralkyl or aryloxy, PA1 k is a number from 3 to 20, PA1 l is a number from 0 to 20, PA1 m is a number from 2 to 20, PA1 n is a number from 1 to 20 and PA1 p is a number from 2 to 10, and PA0 (c) a compound or a combination of compounds, which is capable of initiating the polymerization of the compound (b) under the action of actinic radiation. The mixture is especially suitable for the preparation of dry photoresist materials and is distinguished by good flexibility and adhesion to copper and by easy strippability in the light-cured state.
