    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 multilayer element comprising a substrate, an intermediate layer and a photopolymerizable or photocrosslinkable layer in the stated order is used for producing printing or relief plates. The intermediate layer contains a copolymer of a monomer (A) of the formula (I) or (II) and a copolymerizable monomer (B) ##STR1## where R.sup.1 is vinyl, propen-2-yl, 1-buten-2-yl or styryl or a radical R.sup.2 --O--CO--CH.dbd.CH--, R.sup.2 is an alkyl, aryl, aralkyl or cycloalkyl radical of up to 10 carbon atoms, R.sup.3 is H, methyl or ethyl and n is from zero to 5. The intermediate layer in the multilayer element has improved adhesion in the laminate. It is initially nontacky and does not become tacky until after the application of the photopolymerizable layer, as a result of the interaction with said layer. The improved adhesion in the laminate is retained even after storage and repeated use of the finished printing plates.

    摘要： A multilayer recording element is suitable for the production of flexographic printing plates by digital information transfer and has, arranged one on top of the other on a dimensionally stable substrate, a layer (A) crosslinkable by actinic radiation, a layer (B) sensitive to IR radiation and, if required, a peelable cover sheet, the layer (A) crosslinkable by actinic radiation being capable of being washed out by means of a developer after imagewise exposure and consisting essentially of a mixture of at least one elastomeric binder, ethylenically unsaturated copolymerizable organic compounds, a photoinitiator and, if required, further assistants, and the layer (B) sensitive to IR radiation being a layer which is soluble or dispersible in the developer and contains, in a film-forming binder having elastomeric character, at least one finely divided substance which has a high absorbance in the wavelength range from 750 to 20,000 nm.
