Abstract

Graft copolymers are used for the production of laser-engravable relief printing plates, the graft copolymers being obtained by free radical polymerization of vinyl esters in the presence of polyalkylene oxides and subsequent hydrolysis of the ester function. Processes for the production of transparent flexographic printing plates by means of laser engraving using said graft copolymers are described.
