Definitions

  • Stencil sheets are normally prepared by bonding a thermoplastic resin film to a porous supporting sheet.
  • Typical thermoplastic resins which are so employed include polystyrene, polypropylene, polyethylene and vinylidene chloride-vinyl chloride copolymers.
  • the thickness of the resin film is normally from about 5-10 microns.
  • the weight of the porous supporting sheet is usually from about 8-10 g per square meter. It normally is prepared from a natural fiber obtained from mitsumata, paper mulberry, manila hemp, and the like; or synthetic fibers such as rayon, vinylon, tetron, acrylic resin, or the like.
  • the stencil sheets of the invention are readily prepared by standard processes. For example, the selected amount of heat-fusible compound or compounds is dispersed or dissolved ina solution containing the selected quantity of adhesive. The resultant composition is coated either on a surface of the porous substrate or on a surface ofa thermoplastic film and the substrate and film are bonded to each other and dried. Coating of the adhesive may be effected by roll-coating, spray-coating, and the like.
  • metal salts of fatty acids containing less than carbon atoms or more than 22 carbon atoms While it may be possible to utilize metal salts of fatty acids containing less than carbon atoms or more than 22 carbon atoms, it is most practical to operate in the above defined range.
  • the fatty acid salts having less than 10 carbon atoms have an extremely offensive odor as is well known.
  • EXAMPLE 2 By adding 18 gr of cadmium stearate to 1,500 ml ofa 6 percent methanol solution of vinyl acetate homopolymer, the same as that in Example 1, and dispersing it by mixing well for 3 hours on a ball mill, a liquid adhesive containing a heat fusible compound was prepared. Subsequently, by applying thus prepared adhesive, a thermoplastic film of 7 u thick containing transparent and red-colored (spectrotransparency for the thickness of 450 45 percent) vinylidene chloride vinyl chloride copolymer as the principal component, was bonded onto a porous thin paper.
