ABSTRACT:
Photocrosslinkable polymers which have a mean molecular weight of not less than 5,000 and contain, in side chains, thioxanthone groupings of the formula ##STR1## and, in side chains, imidyl groupings of the formula ##STR2## in which X, Y, Z, n, G.sub.1 and G.sub.2 are as defined in the patent claim, are suitable for the production of highly light-sensitive image materials, for the production of printing plates for the offset printing process and in particular as so-called photoresists for the production of printed circuits. The thioxanthone groupings (I) act as sensitizers for the photocrosslinkable groups of the polymer, so that it is not necessary to add further sensitizers.
