摘要： The invention relates to storage-stable solutions of film-forming copolymers containing carboxyl groups, whose carboxyl groups are reacted to 5 to 80 % with glycidyl (meth)acrylate, in an inert organic solvent or solvent mixture, these solutions additionally containing a phosphoric acid ester of a hydroxyalkyl (meth)acrylate and optionally o-phosphoric acid, and to a procedure for the manufacture of photosensitive coatings which contain photoinitiators, free-radical-polymerisable ethylenically unsaturated organic monomeric compounds, and if appropriate plasticisers, dyes, colour formers and inhibitors of thermal polymerisation, the manufacture of these coatings taking place in a storage-stable solution of this type. They are particularly suitable for the manufacture of offset printing plates.

摘要： In order to prepare acrylate and/or methacrylate polymers containing lateral carbazolyl groups, polymers of acrylyl chloride and/or methacrylyl chloride are reacted in solution in a polymer-analogous reaction with alcoholates of N-( omega -hydroxyalkyl)carbazoles. The poly(meth)acrylates prepared in this way have good photoconductor properties and are advantageously suitable for use in electrophotographic recording elements.

摘要： Methacrylate (co)polymers containing carbazolyl side groups contain or are composed of repeating units of the general formula (I) (I) 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.
