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.
Claims5
A solid photoconductive layer, consisting essentially of methacrylate (co)polymers containing carbazolyl side groups and containing repeating units of the formula (I) ##STR7## where m is an integer of from 3 to 11.
An electrophotographic recording element which is suitable for clamping on drums and cylinders and has a flexible electrically conductive substrate and a solid photoconductive layer applied atop, wherein the photoconductive layer contains at least one methacrylate (co)polymer of the formula (I) ##STR8## where m is an integer of from 3 to 11.
An electrophotographic offset printing plate which can be developed in aqueous alkaline media and has a flexible electrically conductive substrate and a solid photoconductive layer applied atop, containing, as the photoconductor, at least one (meth)acrylate (co)polymer which contains repeating units of the formula (Ia) ##STR9## where R is methyl and m is an integer of from 3 to 11.
