ABSTRACT:
A thermal stencil master sheet for stencil printing has a porous substrate for absorbing ink and a thermoplastic resin film bound thereto by an adhesive. The stencil pattern is formed in both the film and adhesive. The adhesive comprises a thermoplastic resin derived from UV and visible light cured monomers, oligomers and mixtures thereof. In the method provided, thermal stencil master sheets are prepared by forming a liquid layer of adhesive between the porous substrate and the thermoplastic resin film and curing the liquid layer by exposure to UV or visible light.
