    摘要： Process for functionalizing a water-soluble or water-dispersible polymeric organic binder, in which unmodified, water-soluble or water-dispersible polymeric organic binders are reacted with one or more polar aprotic swelling agents which are compatible with the binder, with thorough mixing with one or more compounds which have groups capable of free radical polymerization, compositions obtainable thereby and radiation-sensitive mixtures which contain, as essential components, the above composition, at least one photopolymerization initiator, if required one or more ethylenically unsaturated, photopolymerizable low molecular weight compounds which are compatible with the polymeric binder and further conventional additives and/or assistants, and radiation-sensitive letterpress or relief printing plates which can be produced therefrom.

    摘要： 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 unit and 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(&agr;-methylstyrene), in particular having a spherical or roughly spherical form with a maximum dimension of about 5-10 &mgr;m. The material is very suitable for laser-engravable letterpress printing plates.
