  • Patent number: 10166754
    Abstract: The invention pertains to a printing form and a process for preparing a polymeric printing form from a curable composition that includes a multifunctional urethane in a specified reactive group equivalent weight range, and an initiator. The process includes coating the curable composition onto a supporting substrate, such as a print cylinder, to form a layer, curing the layer with heat or by exposure to actinic radiation, and engraving the resulting cured layer to form at least one printing cell in the cured layer. The process prepares novel polymeric printing forms, particularly novel polymeric gravure printing forms, having a cured polymer-based composition layer that is engravable, resistant to solvent inks, and capable of printing gravure-quality images. The present invention shortens the time to prepare gravure printing cylinders and removes the need for and disposal of toxic heavy metals such as copper and chrome associated with conventional gravure print cylinder preparation.
