| abstract | Transfer copying material has a receiving coating of a film of a polymeric substance that has printing-ink-absorbing pigments evenly dispersed through it. It may comprise a soap wherein are suspended waxes, pigments, foam inhibitors, bleaching agents and resins or polymers. The affinity of the receiver coating for the transfer coating may be adjusted by adding casein, aluminium, calcium, zinc or cadmium salts of stearic or palmitic acid or calcium naphthenate. The ink-absorbing pigment may be kaolin, calcium sulphate, alumina, titanium dioxide, zinc oxide, lithopone, colloidal silica, diatomite or barium sulphate. Receiver coatings in the examples comprise: (6) oleic acid, morpholine, silicone oil, "KPS" wax, polyisobutylene, paraffin wax, polyethylene of low molecular weight, titanium dioxide, kaolin, colloidal silica and water; (7) oleic acid, triethanolamine, stearate foaminhibitor, paraffin wax, polyethylene (as above), lactic casein, titanium dioxide, kaolin and ammoniacal water; and (8) oleic acid, morpholine, silicone oil, ethylene-vinyl acetate copolymer, paraffin wax, polyethylene (as above), acryl polymer or modified maleic resin, lithopone, kaolin, colloidal silica and water.ALSO:Transfer copying material is made by: (1) providing a composition that includes at least one polymer that can form a film adherent to paper, at least one solvent for the polymer, at least one secondary plasticizer in which the polymer is substantially insoluble and pigments dispersed throughout the composition; (2) applying a thin coating of this composition to the back of paper; (3) progressively removing the solvent, so as to form a colloidal precipitate of two phases of polymer and plasticizer, each saturated with the other; and (4) applying to the front of the paper a receiving coating of a film of a polymeric substance that has printing-ink-absorbing pigments evenly dispersed through it. The composition may also include a foam-inhibitor or flocculation-promoting pigments or both. Primary plasticizers may also be present. The pigment may be carbon-black, a phthalocyanine or an organic pigment. The flocculation-promoting pigment may be kaolin, titanium dioxide, zinc oxide, calcium phosphate or lithopane. The receiving coating may comprise a soap wherein are suspended waxes, pigments, foam inhibitors, bleaching agents and resins or polymers. The affinity of the receiver coating for the transfer coating may be adjusted by adding casein, aluminium, calcium, zinc or cadmium salts of stearic or palmitic acid or calcium naphthenate. The ink-absorbing pigment for the front surface may be kaolin, calcium sulphate, alumina, titanium dioxide, zinc oxide, lithopone, colloidal silica, diatomite or barium sulphate. In the examples, donor coatings comprise: (1) titanium dioxide, surface-active agent, calcium sulphate, castor oil, tricresyl phosphate, methyl glycol acetate, carbon-black, ethyl alcohol and alkyd resin; (2) lithopone, castor oil, dibutyl phthalate, ethyl glycol, surface-active agent, phthalocyanine blue, methylene chloride and chlorinated polyethylene; (3) kaolin, titanium dioxide, castor oil, dioctyl phthalate, ethylene glycol, carbon-black, toner red, surface-active agent, ethyl alcohol and polyvinyl alcohol; (4) titanium dioxide, calcium sulphate, castor oil, tricresyl phosphate, methylene glycol, carbon-black, ethyl alcohol and tannic acid-modified phenolic resin; and (5) as in Example (3) but with poly-vinyl butyral in place of the polyvinyl alcohol. Receiver coatings in the examples comprise: (6) oleic acid, morpholine, silicone oil, "KPS" wax, polyisobutylene, paraffin wax, polyethylene of low molecular weight, titanium dioxide, kaolin colloidal silica and water; (7) oleic acid, triethanolamine, stearate foam-inhibitor, paraffin wax, polyethylene (as above), lactic casein, titanium dioxide, kaolin and ammoniacal water; and (8) oleic acid, morpholine, silicone oil, ethylenevinyl acetate copolymer, paraffin wax, polyethylene (as above) acryl polymer or modified maleic resin lithopone kaolin colloidal silica and water.ALSO:Transfer copying material is made by: (1) providing a composition that includes at least one polymer that can form a film adherent to paper, at least one solvent for the polymer, at least one secondary plasticizer in which the polymer is substantially insoluble and pigments dispersed throughout the composition; (2) applying a thin coating of this composition to the back of paper; (3) progressively removing the solvent, so as to form a colloidal precipitate of two phases of polymer and plasticizer, each saturated with the other; and (4) applying to the front of the paper a receiving coating of a film of a polymeric substance that has printing-ink-absorbing pigments evenly dispersed through it. The composition may also include a foam-inhibitor or flocculation-promoting pigments or both. Primary plasticizers may also be present. When such sheets are superposed, the front of the top sheet can be typed upon, and copies of the typed matter will appear on the underlying sheets. The pigment may be carbon-black, a phthalocyanine or an organic pigment. The flocculation-promotion pigment may be kaolin, titanium dioxide, zinc oxide, calcium phosphate or lithopane. The receiving coating may comprise a soap wherein are suspended waxes, pigments, foam inhibitors, bleaching agents and resins or polymers. The affinity of the receiver coating for the transfer coating may be adjusted by adding casein, aluminium, calcium, zinc or cadmium salts of stearic or palmitic acid or calcium naphthenate. The ink-absorbing pigment for the front surface may be kaolin, calcium sulphate, alumina, titanium dioxide, zinc oxide, lithopone, colloidal silica, diatomite or barium sulphate. The front coating can be printed upon. In the examples, donor coatings comprise: (1) Titanium dioxide, surface-active agent, calcium sulphate, castor oil, tricresyl phosphate, methyl glycol acetate, carbon-black, ethyl alcohol and alkyd resin; (2) lithopone, castor oil, dibutyl phthalate, ethyl glycol, surface-active agent, phthalocyanine blue, methylene chloride and chlorinated polyethylene; (3) kaolin, titanium dioxide, castor oil, dioctyl phthalate, ethylene glycol, carbon-black, toner red, surface-active agent, ethyl alcohol and polyvinyl alcohol; (4) titanium dioxide, calcium sulphate, castor oil, tricresyl phosphate, methylene glycol, carbon-black, ethyl alcohol and tannic acid - modified phenolic resin; and (5) as in Example (3) but with poly-vinyl butyral in place of the polyvinyl alcohol.
