    摘要: The invention relates to a process for the preparation of a two-coat finish on a substrate surface, in which process a basecoat is employed which contains as binder a polymer which can be obtained by subjecting an ethylenically unsaturated monomer or a mixture of ethylenically unsaturated monomers to free-radical polymerization in an aqueous dispersion of a polyurethane resin which has a number-average molecular weight of from 1000 to 30,000 and contains on average from 0.05 to 1.1 polymerizable double bonds per molecule, and in the presence of a water-insoluble initiator or of a mixture of water-insoluble initiators, the weight ratio of the polyurethane resin to the ethylenically unsaturated monomer or to the mixture of ethylenically unsaturated monomers being between 1:10 and 10:1.

    摘要: Flexible printing plates are produced from printing plates consisting essentially of a dimensionally stable substrate (1) and a recording layer (2) by a process in which the printing plate is produced alternatively either by photochemical or by mechanical structuring, and in the case of photochemical structuring the photosensitive recording layer (2) is exposed imagewise and the unexposed parts of the recording layer (2) are washed out with a developer and in the case of mechanical structuring the originally photosensitive, uniformly exposed recording layer (2) is cut imagewise and the nonprinting parts of the recording layer (2) are peeled off from the substrate (1).The printing plates produced by this process are suitable for the production of products printed by the flexographic method and for lacquering products printed by the offset method.
