    Abstract: PROBLEM TO BE SOLVED: To obtain excellent seal joint strength by a method wherein a substrate is coated with an aqueous dispersed solution containing an ethylene polymer containing respective specific amounts of ethylene and en ethylene unsaturated acid, and a radical polymerized polymer, and the coated substrate is fixed by pressure to a base material at a high temperature. SOLUTION: A substrate is sheets of aluminum, polyvinyl chloride, carbon packaging, etc. An aqueous dispersed solution contains an ethylene polymer, and a radical polymerized polymer. The ethylene polymer contains at least 20wt.% of ethylene, at least 5wt.% of ethylenic unsaturated acid (acrylic acid or the like), and 0-60wt.% monomer different therefrom. The radical polymerized polymer contains 30-100wt.% of principal monomer selected from among C1 -C20 alkyl (meth)acrylate and the like. The aqueous dispersed solution is used as sealing lacquer, and coated on the base material, which is integrated by pressure with a non-coated second base material at 80-250 deg.C temperature.

    IPC: G03F7/18

    Abstract: Prodn. involves: (a) seamless application of a photocopying element with a photopolymerisable layer to the surface of a cylinder; (b) buffing the surface of this layer; (c) smoothing the buffed surface by (c-1) treatment with an organic solvent (mixt.), in which the layer is soluble or dispersible, and/or (c-2) filling the buffed relief with a thermoplastic binder, and/or (c-3) applying heat and/or pressure; (d) selective exposure with actinic light; and (e) development by washing out the unexposed areas with a suitable solvent (mixt.). The novelty is that a water-in-oil emulsion (I) is used in stages (c-1), (c-2) and/or (e). (I) contains a finely dispersed aq. phase and a continuous nonflammable or hardly flammable and/or high boiling organic phase (II) in 90:10 to 10:90 vol. ratio.

    Abstract: The invention relates to a process for the production of relief formes. After exposing layers which can be crosslinked by photopolymerisation to actinic light through an image, the uncrosslinked portions of the layers are washed out with hydrocarbon solvents or mixtures of hydrocarbon solvents and alcohols, certain hydrogenated petroleum fractions being used as hydrocarbon solvents. The process is suitable, in particular, for the production of flexographic printing formes.
