  • A PRINTING FORM PRECURSOR AND PRINTING FORM THEREOF
    Publication number: 20250313695
    Abstract: The invention pertains to a printing form precursor, and particularly a printing form precursor that can form printing forms, or printing plates, having improved properties. The printing form precursor includes a photopolymerizable composition containing an additive having a structure of Formula (I). The presence of the additive results in ease of processing and/or better cleanout and reduction in webmarkings on solid areas of the printing form.

  • Printing form precursor having indicia and a method for preparing a printing form from the precursor
    Patent number: 9477152
    Abstract: The present invention relates to a photosensitive printing form precursor and a method for forming a printing form from the precursor. The precursor includes a support and a layer of a photosensitive composition adjacent the support, in which at least one indicia is disposed between the support and the photosensitive layer. The indicia identifies the precursor, is retained throughout a multi-step process to convert the precursor into a printing form and in the end-use of the printing form.

  • Photosensitive element for use as flexographic printing plate
    Publication number: 20040234886
    Abstract: A photosensitive element for use as a flexographic printing plate comprises a support, an elastomeric photopolymerizable layer having a surface opposite the support that defines a plane, and a matted layer disposed above the surface of the photopolymerizable layer comprising a polymeric binder and at least one matting agent which is capable of forming depressions from the plane into the photopolymerizable layer. Also described is a process for preparing such a photosensitive element and a process for preparing a flexographic printing plate from the photosensitive element.

  • Corrosion resistant, radiation curable coating
    Patent number: 6211262
    Abstract: A corrosion resistant coating for metal surfaces curable with actinic radiation. The blend uses acrylate resin, photoinitiator and a corrosion preventing agent such as a metal surface passivator, overbased calcium sulfonate/calcium carbonate, a barrier pigment, or a combination of two or more of these agents.
