    Abstract: Magnetic recording media comprising a non-magnetic substrate and a magnetic layer comprising a finely divided magnetic material dispersed in an organic solvent soluble, crosslinkable, essentially linear, thermoplastic polyurethane which possesses acrylate side and terminal groups wherein said polyurethane is prepared by reacting poly- and/or diisocyanates with a mixture of (a) methacrylate - or acrylate - diols having molecular weights of from 146 to 3,000, (b) monoesters of methacrylic or acrylic acid and a diol having a molecular weight of from 116 to 300, and (c) other organic polydiol compounds which have molecular weights of from 400 to 5,000.

    Abstract: A process for the production of coatings based on reaction products of (A) mixtures of (A1) polyhydroxypolyacrylate resins obtained from hydroxylalkyl esters of acrylic acid and/or methacrylic acid, alkyl esters of acrylic acid and/or methacrylic acid, and one or more polymerizable, olefinically unsaturated nitrogen-containing heterocyclic compounds, with or without vinylaromatics, (meth)acrylamides and other monomers, and (A2) polyesterpolyols with (B) isocyanurate-containing polyisocyanates which may or may not contain biuret groups, have a functionality of from 2.5 to 6 and possess predominantly cycloaliphatically bonded isocyanate groups, some of which may be replaced by aliphatically bonded isocyanate groups. The process is particularly useful for coating metal components.

    Abstract: A laminate suitable for the production of printing plates and relief plates, and possessing a photosensitive layer, which is soluble in water or in an aqueous solution, and contains a hydrophilic polymeric binder, applied to a base, contains, between the base and the photosensitive layer, an intermediate layer which consists of a mixture of a polymeric binder compatible with the polymeric binder of the photosensitive layer, and a diacrylate or dimethacrylate monomer which contains urethane groups and is obtained by reacting a hydroxyalkyl acrylate or hydroxyalkyl methacrylate with a diisocyanate. After application to the base, the intermediate layer is cured at 110 DEG -220 DEG C. before the photosensitive layer is applied.
