Photocrosslinkable compositions for screen printing stencils |
摘要 |
Screen printing stencils are prepared by afixing to a printing screen substrate an indicia-defining, ultraviolet-sensitive film and cross-linking the film by exposure to ultraviolet radiation. The coating compositions used to form the film comprise copolyacrylate/polyurethane block copolymers, in which the copolyacrylate blocks are copolymers of at least one hydroxy-containing acrylate and at least one acrylate or methacrylate which may be partially substituted with bromine, ultraviolet initiators and cross-linking monomers. Screen printing stencils are provided which are compatible with both water-based and oil-based inks. The disclosed screen printing stencils are used in improved screen-printing methods.
