Patent GB-1028618-A (GB)
Title: Transfer compositions
IPC: B41M5/10
Filed: 1965-01-27
Abstract: Ink compositions for pressure operative transfer media comprise a polymer base material, colouring matter, a non-volatile, non-drying carrier fluid for the colouring matter and a quaternary ammonium compound in such amount that the colouring matter is more readily released.  The polymer bases may be polymers of vinyl chloride, vinylidene chloride, vinyl butyral, vinyl acetate, styrene, methyl styrene, methyl acrylate or methyl methacrylate; cellulose ethers or esters; or polycarbonate, polyester or epoxy resins.  The quaternary ammonium compound preferably contains at least one C8- 24 hydrocarbon radical, or may be an alkyl pyridinium salt.  The compositions may also comprise fillers, e.g. china clay, mica, burnt umber, calcium sulphate, barium sulphate, talc, titanium dioxide and diatomaceous earth. The components may be dissolved and dispersed in a volatile solvent and applied to paper, fabric and plastic foil sheets, ribbons or tapes to form transfer media. Examples describe compositions comprising methylene chloride, colouring matter, fillers and (I) vinyl chloride/vinyl acetate copolymer, oleyl alcohol, butyl stearate and oleyl dimethyl ethyl ammonium ethyl sulphate; (II and V) vinyl chloride/vinyl acetate copolymer, oleyl alcohol and lauryl dimethyl benzyl ammonium chloride; (III and IV) vinyl chloride/vinyl acetate copolymer, oleyl alcohol, ground nut oil, butyl stearate and oleyl dimethyl ethyl ammonium ethyl sulphate; (VI) vinyl chloride/vinylidene chloride copolymer, oleyl alcohol, ground nut oil, butyl stearate and oleyl dimethyl ethyl ammonium ethyl sulphate; (VII) vinyl chloride/vinylidene chloride copolymer, oleyl alcohol, ground nut oil, butyl stearate and lauryl dimethyl benzyl ammonium chloride; (VIII) vinyl chloride/vinyl acetate copolymer, oleyl alcohol, ground nut oil, butyl stearate and oleyl dimethyl ethyl ammonium ethyl sulphate; the polycarbonic acid ester of 2,2-bis-(4-hydroxyphenyl) propane and (IX) castor oil, dioctyl adipate and octadecyl carboxymethyl trimethylammonium chloride, or (X) ground nut oil, dioctyl sebacate and oleyl dimethyl ethyl ammonium ethyl sulphate; and (XI) vinyl chloride/vinyl acetate copolymer, oleic acid, butyl stearate and oleyl dimethyl ethyl ammonium ethyl sulphate.ALSO:Pressure operative transfer media comprise a base sheet coated with an ink composition comprising a polymer base material, colouring matter, a non-volatile, non-drying carrier fluid for the colouring matter and a quaternary ammonium compound in such amount that the colouring matter is more readily released.  Specified polymer base materials are polymers of ethylenically unsaturated compounds such as vinyl chloride, vinylidene chloride and vinyl acetate; cellulose ethers and esters; and polycarbonate, polyester and epoxy resins.  The compositions may be applied from solutions or dispersions in volatile solvents to paper, fabrics and plastic foils.  Many suitable components are listed and examples describe transfer media comprising paper bearing inks comprising, colouring matter and (I and XI) vinyl chloride/vinyl acetate copolymer, oleyl alcohol, butyl stearate and oleyl dimethyl ethyl ammonium ethyl sulphate; vinyl chloride/vinyl acetate copolymers, oleyl alcohol, butyl stearate, ground nut oil and (VI) oleyl dimethyl ethyl ammonium ethyl sulphate and VII lauryl dimethyl benzyl ammonium chloride; and VIII) a vinyl chloride/vinyl acetate copolymer, a vinyl chloride/vinylidene chloride copolymer, oleyl alcohol, butyl stearate, ground nut oil and oleyl dimethyl ethyl ammonium ethyl sulphate; comprising polyethylene terephthalate films coated with a polyvinyl formal bonding layer and inks comprising colouring matter, oleyl alcohol and (II and V) lauryl dimethyl benzyl ammonium chloride and (III and IV) ground nut oil, butyl stearate and oleyl dimethyl ethyl ammonium ethyl sulphate; and comprising bases coated with inks comprising colouring matter, polycarbonate resins derived from bisphenol A and (IX) castor oil, dioctyl adipate and octadecyl carboxymethyl trimethyl ammonium chloride and (X) ground nut oil, dioctyl sebacate and oleyl dimethyl ethyl ammonium ethyl sulphate.
