Abstract
Methacrylate (co)polymers containing carbazolyl side groups contain or are composed of repeating units of the general formula (I) ##STR1## where m is an integer of from 3 to 11. The novel methacrylate (co)polymers containing carbazolyl side groups can advantageously be used as photoconductors in photoconductive layers, in particular of electrophotographic recording elements.
