ABSTRACT:
An electrophotographic copying material is disclosed containing, in the photoconductive film, a high-molecular-weight polymer binder which is a graft polymer having a polyurethane as grafting base and grafted-on chains which contain vinyl alcohol units. The material is suitable, in particular, for the production of printing plates and printed circuits which are highly photosensitive and laminatable even at fairly large film thickness. The films can be treated with mild and toxicologically safe stripper solutions.
