ABSTRACT:
Photocrosslinkable polymers having an average molecular weight of at least 1,000 and side groups of the formula Ia and/or Ib ##STR1## in which R, R', R.sub.1, R.sub.2, A, E, Y and n are as defined in claim 1, are suitable, for example, for preparing solvent-resistant coatings on metals and, in particular, for preparing printing plates or printed circuits. The group of the formula Ia and/or Ib content is at least 0.5%, preferably 5-100%, based on the number of the polymer's recurring structural elements.
