    摘要： Aromatic amines are obtained from the corresponding cycloaliphatic oximes by heating the oxime to a temperature of from 150.degree. to 350.degree. C. in an ether group containing solvent in the presence of a catalyst containing a noble metal of the 8th auxiliary group of the Periodic Table of Elements. The solvent is preferably an aliphatic ether, especially a lower dialkyl ether of a polyethyleneglycol.

    摘要： Polymers comprising perfluoroalkyl groups, reproduction layers containing these polymers and use thereof for waterless offset printing. The novel perfluoroalkyl group-containing polymers comprise polymers or polycondensates and have, in each case as substituents on different carbon atoms of benzene rings, phenolic OH groups and perfluoroalkyl groups which are optionally attached through intermediate members. In particular, at least 10% of the polymer units carry perfluoroalkyl groups. These polymers are either formed by condensation of substituted phenols (e.g., 4-hydroxybenzoic acid-perfluoroalkyl ester) with an aldehyde, a ketone, or a reactive bismethylene compound or by reacting polymers containing phenolic OH groups (e.g., hydroxypolystyrene) or polycondensates containing reactive OH groups (e.g., phenol-formaldehyde resins) with a perfluoroalkyl group-containing compound (e.g., 2,2-dihydroperfluorodecanoic acid chloride). The novel polymers are particularly useful in radiation-sensitive reproduction layers which additionally contain at least one radiation-sensitive compound. Reproduction layers of this kind are applied as radiation-sensitive coatings to support materials for printing plates used in waterless offset printing.

    摘要： Copolymers comprising perfluoroalkyl groups, reproduction layers containing these copolymers and use thereof for waterless offset printing. The novel perfluoroalkyl group-containing copolymers are prepared from at least two different monomers, monomer (a) comprising acryloyl or methacryloyl groups and phenolic OH groups and monomer (b) comprising acryloyloxy, methacryloyloxy or vinyl groups and a perfluoroalkyl group. Monomer component (a) can, for example, be prepared from a hydroxybenzoic acid by esterification with a hydroxyalkyl-acrylate. The novel copolymers are, in particular, used as binders in radiation-sensitive reproduction layers which additionally contain at least one radiation-sensitive compound. Reproduction layers of this kind are used as radiation-sensitive coatings of support materials for printing plates used in waterless offset printing.
