Beschreibung
Zusammenfassung:	A material for gravure recording by means of coherent electromagnetic radiation for letterpress printing, consisting of a substrate and a crosslinkable layer, with or without a release layer and/or cover sheet, the layer containing at least one ethylenically unsaturated compound, a polymerization initiator and at least one polymeric binder which consists of polyvinyl alcohol and/or at least one copolymer having a substantial proportion of the structural unitand containing a filler having a ceiling temperature of less than 800K, in particular less than 600K, e.g. polystyrene, polymethyl methacrylate, poly(ethylene)ketone, polyoxymethylene or poly(alpha-methylstyrene), in particular having a spherical or roughly spherical form with a maximum dimension of about 5-10 mum. The material is very suitable for laser-engravable letterpress printing plates.
