  • Processes and apparatus for producing photopolymerizable, cylindrical, continuous, seamless flexographic printing elements
    Patent number: 8066837
    Abstract: Processes comprising providing a layer composite comprising a layer of photopolymerizable material and a removable substrate film disposed on one side of the layer of photopolymerizable material, wherein the photopolymerizable material comprises an elastomeric binder, an ethylenically unsaturated monomer and a photoinitiator; and (a) miter-cutting two edges of the layer composite to be joined, to form two miter-cut ends; (b) providing a hollow cylinder on a rotatably mounted support cylinder, wherein the hollow cylinder has an outer surface and is in a temporarily locked position relative to the support cylinder; (c) applying an adhesion-promoting layer to the outer surface of the hollow cylinder; (d) applying the layer composite to the hollow cylinder bearing the adhesive-promoting layer, wherein the layer composite is disposed on the hollow cylinder such that the removable substrate film faces away from the hollow cylinder and the two miter-cut ends lie substantially one on top of the other, but not overlap

  • Method for the production of photopolymerizable, cylindrical, continuous seamless flexographic printing elements, and use thereof for the production of cylindrical flexographic printing forms
    Publication number: 20060249239
    Abstract: Photopolymerizable cylindrical, continuously seamless flexographic printing elements are produced by applying a layer of a photopolymerizable material to the outer surface of a hollow cylinder and joining the edges by calendering. Flexographic printing elements produced in this manner are used for the production of flexographic printing plates.

  • Preparation of polyaspartic acid
    Patent number: 5830985
    Abstract: A process for preparing polyaspartic acid by polycondensation of fine-particle aspartic acid at temperatures above 150.degree. C. in the presence of acidic catalysts, wherein first contact between the acidic catalysts and the fine-particle aspartic acid takes place in the reaction zone where the polycondensation takes place.
