    摘要： A stencil printing paper and a process for perforating and engraving the same having the advantages in that the production of the stencil printing paper is easy, the resulting production cost can be thereby reduced and there is no generation of any problem at a time of stencil-making. In a stencil printing paper constituted by laminating a solvent-soluble resin layer to a porous substrate, the present invention comprises a stencil printing paper containing an acetalized polyvinyl alcohol having an acetalization degree of 1-70 mol % and a process for perforating and engraving the stencil printing paper by a mixed solvent containing water and an alcohol type solvent.

    摘要： A duplicating stencil is produced by placing an electrostatically-produced image on a substrate in contact with an ink-impervious surface layer of a stencil blank, bonding the image to the surface layer by the application of heat and/or pressure and stripping the substrate from the stencil blank to remove the surface layer in the image area. The surface layer may comprise a synthetic resin composition containing a finely dispersed pigment and is attached to the porous base tissue of the stencil blank by an adhesive. Bonding of the image to the surface layer and possibly also fixing of the image to the substrate in the same operation can be effected by means of infra-red heating.

    摘要： There is disclosed an improvement in the mimeograph stencil art comprising the manufacture of an overlay sheet for either a conventional typewriter stencil or in particular a stencil which can be prepared by means of heat transfer with a thermocopier and with this overlay sheet is capable of either thermal production or conventional typewritten production, comprising a sheet of tissue which has been coated on one side, only, with a film of elastomeric plastic, such as polyvinyl chloride or polypropylene.
