Definitions

• This invention relates to transfer materials by which term is meant sheet materials which comprise a carrier sheet carrying, on a surface thereof, a layer, or one or more printed indicia (herein called the transferable material), which while adherent to the carrier sheet can be released therefrom and transferred to a desired receptor surface when required.
• Transfer materials are known and commercially produced which comprise essentially a carrier sheet, transferable material on a surface thereof, and a low-tack pres. sure sensitive adhesive superimposed over the transferable material, the whole so constructed that when such transfer material is laid down with the adhesive in contact with a desired receptor surface, the transferable layer will not, under light pressure, such as ordinary finger pressure, e.g. less than 2 p.s.i. transfer to the receptor surface but will, nevertheless, transfer on application of substantial pressure, e.g. that applied by rubbing the back surface of the transfer material, in the region of the transferable material which is to be transferred, with a stylus or the like.
• Such materials are described in British patent specifications Nos. 906,9'34 and 959,670.
• the transferable material consists of a plurality of indicia, e.g. the letters of the alphabet, numbers, mathematical signs, codes and the like, which may be separately and bodily transferred to a desired receptor surface as required so that, for example, words may be built up on the receptor surface by the successive transference of letters from the transfer material.
• indicia e.g. the letters of the alphabet, numbers, mathematical signs, codes and the like
• bodily transfer is meant that the whole indicium transfers leaving no part of it on the carrier sheet.
• a transfer material which comprises a carrier sheet and, superimposed on a face of said sheet a layer of one or more indicia in a transferable material which is an ink itself containing a pressure sensitive adhesive ingredient, the said transferable material having a surface of low tack and the adhesive properties of the transferable material being so balanced in relation to the surface of the carrier sheet and a receptor sheet that when the transfer material is laid down with the transferable material surface in'contact with a receptor sheet the layer or indicia of transferable material does not transfer bodily under light pressure, e.g. normal finger pressure, but does transfer under the application of substantial pressure applied to the back surface of the carrier sheet e.g. by rubbing with a stylus, in the region of the transferable material to be transferred, at a pressure above 50 p.s.i.
• the carrier sheet should be one having a surface from which the transferable material (adhesive ink) may be bodily removed by application of pressure or by localised stretching of the carrier sheet.
• Suitable carrier sheets are, for example, sheets consisting of glassine or vegetable parchment, or papers such as glassine, vegetable parchment, kraft, sulphate or the like coated or impregnated with a cured polymethyl siloxane, or a Werner type chromium complex such as the stearic acid or myristic acid complex, or alternatively a plastic film such as polyethylene, polytetrafiuoroethylene, polypropylene, cellulose acetate, cellulose acetate butyrate, cellulose nitrate, ethyl cellulose, polycarbonate, polystyrene-butadiene, polyvinyl chloride, polyvinyl acetate, polyvinylidene chloride or copolymers or polyesters such as polyethylene terephthalate or hexamethylene diamine adipate.
• plastic film such as polyethylene, polytetrafiuoroethylene, polypropylene, cellulose acetate, cellulose acetate butyrate, cellulose nitrate
• the pre ferred carrier sheet is vegetable parchment treated with a coating of methylpolysiloxane of a non-migrating type.
• carrier sheet should be transparent or translucent since this makes for ease in location of the transfer material in use. It is to be understood that the term carrier sheet is used herein to include a carrier tape.
• the transferable material comprises ink ingredients including a proportion of a wax.
• Suitable waxes are carnauba wax, microcrystalline wax, oxidised microcrystalline wax, polythene wax, candolilla, beeswax, hydrogenated castor oil, montan wax, paraffin wax, carboxylic acids, esters or amides or polymers of these and long chain alcohols and polyglycols.
• transferable material which consists essentially of ink ingredients and wax may usefully be employed, as above noted, the inclusion of a wax in an ink composition generally tends to reduce the tensile strength of the composition. Accordingly, in using products so made it is important that the transfer pressure should be applied over the whole of the area of the material to be transferred; omission of any area may result in that area not being caused to adhere to the receptor surface. In certain forms of the product this is not a disadvantage, e.g. where the indicia consist of closely spaced small shading dots or lines and the material is used to transfer such dots or lines only over a precisely selected area.
• the indicia are of greater size, eg letters or numerals
• it is preferred that the indicia should transfer even though strokes of a stylus may be slightly spaced apart during the transfer operation, and not cover every part of the area of the indicium and to achieve this result it is desirable that the transferable material should have a higher tensile strength.
• the transferable material is formed of an ink which includes a tacky pressure-sensitive adhesive component together with a waxy or other non-tacky deformable component, the proportion of the non-tacky component being sufiicient to reduce the tack of the final composition to a level at which it will not adhere to a receptor surface under slight or finger pressure, the said composition further including a proportion of a high tensile strength polymer.
• the tacky component may, for example, be a tacky acrylic or methacrylic ester or acid polymer or copolymer, a vinyl ether or ester, terpene, cresylic, maleic, or phenolic resin, or natural or synthetic rubbers such as neoprene or isoprene or cyclised rubber, or chlorinated rubber or such materials containing non-volatile plasticisers such as saturated polyesters, or non drying alkyds, or mixtures thereof.
• a tacky acrylic or methacrylic ester or acid polymer or copolymer a vinyl ether or ester, terpene, cresylic, maleic, or phenolic resin
• natural or synthetic rubbers such as neoprene or isoprene or cyclised rubber, or chlorinated rubber or such materials containing non-volatile plasticisers such as saturated polyesters, or non drying alkyds, or mixtures thereof.
• the non-tacky component may, for example, be a high melting point long chain hydrocarbon, or carboxylic acid ester or amide thereof, or polymers of any of these, or a long chain alcohol or a polyglycol, or a natural wax.
• Preferred high tensile strength polymers for use in this form of the invention are polyvinyl butyral or ethyl cellulose.
• Other suitable materials are cellulose nitrate; cellulose acetate; cellulose acetobutyrate; ethyl cellulose, ethylhydroxyethyl cellulose; alkyds and alkyds modified or copolymerised with a drying oil, styrene, urethane, vinyl, silicone or acrylic resin; polyvinyl-halides, -esters-acetals and alcohols; polyurethanes; epoxy polymers; epoxy phenolic, epoxy-polyamide and catalysed epoxy resins and copolymers; urea-, melamine-, and benzoguanamino-formaldehyde polymers; chlorinated and isomerised rubber; polystyrene and polyvinyl toluene; polysiloxanes and silicone containing polymers; polyacrylates, polymeth
• the ink consists essentially of a tacky component and a non tacky component as aforesaid, a high tensile strength polymer, and a pigment.
• the ingredients may be applied as a solution, dispersion or emulsion in organic solvent medium or water, the solvent or water being dried out after application.
• the indicia may be of any kind, e.g. letters, numerals, symbols, line drawings or the like. Particularly useful products are those in which the ink is applied as a texture pattern extending substantially over the whole area of the carrier sheet, i.e. so that the whole transferable layer is of said texture pattern.
• texture patterns may be for example an array of dots, shading lines, parallel or crossed, or irregular paterns, to simulate grain, textile fibre mat or other texture appearances.
• the indicia will only transfer where the pressure is applied so that localised areas of the texture pattern may be transferred.
• an outline drawing of a figure wearing a skirt may be treated with a transfer material according to this invention which carries a pattern simulating textile finish by applying transfer pressure only within the confines of the skirt outline so as to transfer the textile pattern to the skirt portion only of the drawing. Since in this case the transfer is required to be closely limited to the area over which the pressure has been applied it is desirable to employ an ink of suitable level of cohensiveness (as referred to later herein) in order that the layer'should fracture at the margins of the pressed area.
• a method for the production of a transfer material which comprises applying to a carrier sheet a layer, or indicia, in transferable material which has, or is enabled to develop, a tacky surface sufiicient to enable it to adhere to a receptor surface under substantial pressure while the face of the transferable material originally in contact with the carrier sheet is or becomes substantially non-tacky. It will be appreciated that the merit of this technique is that there is substantially no tendency for the transferred indicia to pick up dirt on their surface.
• any convenient pigment well known for use in printing inks may be used in the ink formulations of the present invention including pigments modified by coating the pigment particles with surface active agents to improve dispersability and increase covering power. It will be appreciated that changes in pigmentation whether utilising unmodified materials or materials modified as aforesaid will involve other formulation changes in order to provide inks possessing the desirable properties for the transferable material of this invention.
• Pigments of particular value are carbon blacks and titanium compounds whilst modified pigments of particular interest are those in which the pigment particles are coated with aluminum or zinc stearates of amides of stearic acid.
• Transfer materials of particular value are obtained when employing inks formulated Within the range encompassed by the following formulations in conjunction with the carrier sheets of vegetable parchment having a silicone coating.
• the dried ink will contain the first four only of the specified ingredients in the indicated relative parts by weight. It will be appreciated that alternative pigmentation will necessitate other variations in composition of the foregoing formulations and such variations should be made in cognisance of the working behaviour of the ink and the ultimate properties desirable in the transferable indicia.
• the cohesiveness refers to the property of the ink film when present on the carrier film in its normal condition for use as a transfer material. This range of formulations are very suitable for use when 5 the carrier sheet is in the form of a tape as there arises no trouble due to oif-setting when the tape is rolled.
