Definitions

  • a top sheet and at least one copy sheet of a set of printed forms, or other transfer set, of colour reaction paper are integrally joined across a fold line.
  • the colour receiving layer on the top surface of the copy sheet is also applied in a single operation, before the folding, to the lower surface of the top sheet.
  • Over the receiving layer on the lower surface of the top sheet there is subsequently applied a layer of a neutralising agent and, over the neutralising agent layer, at those parts of the top sheet which are intended for transmitting the typed message, a printed colour forming layer.
  • the invention relates to a transfer set incorporating colour reaction sheets, the set consisting of a top sheet and at least one copy sheet, the under surface of the top sheet being coated, over at least a part of its area, with a colour forming layer, and the upper surface of each copy sheet being coated with a colour receiver.
  • a set of the kind described above usually consists of three different kinds of sheets: a top sheet, one or more intermediate sheets and a bottom sheet.
  • the under surfaces of the top and intermediate sheets are coated with a colour forming layer, whereas the upper surfaces of the intermediate and bottom sheets are coated with a colour receiving layer consisting essentially of a clay, or an acid treated clay which has adsorbent properties.
  • the upper surface of the top sheet and the'under surface of the bottom sheet are uncoated, although the upper surface of at least the top sheet may carry a printed message when the tarnsfer set is a set of printed forms.
  • the colour forming layers on the under surfaces of the top and intermediate sheets consist, in the known way, of a solution of colour forming substances contained in microcapsules, which are applied in the form of a dispersion, or alternatively th solution of colour forming substances can be contained in an emulsion or in a spongy layer of a synthetic plastic material, or in a layer of a meltable binder.
  • the colour receiving layers on the upper surfaces of the intermediate and bottom sheets consist of pigment-forming materials which react with the colour forming layer, the nature of the reaction'depending on the particular substances used. These reactions are known and are not a part of the present invention.
  • the object of the present invention is to provide transfer sets capable of satisfying the special requirement mentioned above, using colour reaction sheets for the sake of their special advantages.
  • a transfer set of colour reaction sheets comprises a single sheet folded to form a top sheet and at least one copy sheet, the surface of the single sheet which forms the lower surface of the top sheet and the upper surface of the copy sheet being coated with an integral colour receiving layer, which, on the lower surface of the top sheet, is covered with a layer of a neutralising agent for preventing the colour reaction, those parts of the top sheet which are intended for transmitting the typed message being provided with a printed colour forming layer superposed over the neutralising layer.
  • both surfaces of the single sheet are coated with colour receiving layers and the lower surface of the or each intermediate copy sheet is provided with a layer of a neutralising agent partly overprinted with a colour forming layer.
  • the transfer set may be manufactured as follows. To one surface of a single sheet of paper or foil there is first of all applied, by a suitable machine, a coating of material to form a colour receiving layer, as mentioned at the beginning for the copy sheet. In the next operation the under surface of the part of the single sheet which will become, after folding, the top sheet is coated with a neutralising agent layer, which is superposed over the existing colour receiving layer. When this has been done the neutralising areas can no longer act as colour receiving areas when they come into contact with a colour forming layer, because in these areas the colour receiving layer has been covered over and neutralised by the superposed neutralising layer. In a further operation a special colour forming layer is applied to parts of the neutralising agent layer by the hot-spot printing process.
  • the ribbon which has been treated in this way is then folded so that the coated surfaces come together.
  • the folding can produce one or more creases, depending on how many copy sheets are required. For example if only one copy sheet is required the original sheet is folded along its middle, giving a top sheet and a copy sheet which are firmly attached together. Consequently when typing is applied to the top sheet at the locations where the colour forming layer has been applied on the under surface of the top sheet, this layer reacts with the colour receiving layer on the upper surface of the copy sheet, giving a visible message on the copy sheet. A visible message on the copy sheet can be produced only under those areas of the top sheet where the colour forming layer has been applied to its under surface.
  • the neutralising layer constitutes a reliable barrier layer separating the superposed colour former layer from the subjacent colour receiver layer.
  • intermediate sheets can be provided either by inserting extra sheets, or by the multiple folding method mentioned above.
  • the neutralising agent layer occupies an area between 1 and 2 mm. wider and longer than the superposed colour forming layer, which consists of a special mixture of materials. It has also been found advisable to tint the neutralising agent slightly, by adding a dye, so as to make it easier for the printer to control his operations.
  • the neutralising agent mentioned above is a liquid and is applied by a method similar to that used for the so called Flexobuch colours.
  • the neutralising substance contains a film former dissolved in an organic solvent.
  • the film former can be a resin, preferably a non-saponifiable resin, such as a ketone resin.
  • the film former can consist of an easily soluble synthetic resin, for example polyvinylpyrrolidone, but this synthetic resin must also be non-saponifiable.
  • solvents for the neutralising agent there'can be used a non-saponifiable alcohol, preferably ethyl alcohol, but alternatively if desired isopropyl alcohol, or mixtures of these two can be used.
  • the solvent should have a low boiling point to ensure that the printed layer dries quickly.
  • the neutralising agent may contain, in addition to the film former and the solvent, five to twenty percent of a hygrophilic plasticiser, for example polyethylene glycol.
  • the active neutralising agent may be a base, for example an amine, preferably triethanolamine.
  • base for example an amine, preferably triethanolamine.
  • other basic substances can be used, provided that they are easily soluble in organic solvents, and provided that they are compatible with the particular film former.
  • a pigment in the form of a highly dispersed silicic acid product which provides a very large surface area, for example Aerosil.
  • a neutralising :agent of this kind covers the colour receiver layer sufliciently when applied in a thickness corresponding to 3 to 7 g./m. preferably 4 to 5 g./m. Over the neutralised surface a colour forming layer can be printed by the hot-spot printing method.
  • FIG. 1 is a cross section representing diagrammatically the principle of a transfer set according to the invention
  • FIG. 2 is a perspective view showing a single-piece folded set
  • FIG. 3 is a cross section through a further example of a set according to the invention.
  • a top sheet 1 is coated on its lower surface with a colour receiving layer 2, and over that a neutralising layer 3, and finally a colour forming layer 4.
  • the upper surface of the copy sheet is coated with a colour receiving layer.
  • the two sheets will in fact be connected across a fold line as shown in FIG. 2.
  • FIG. 2 is a single-piece set which has been folded along a line to form a top sheetand a copy sheet.
  • the coatings are as described for FIG. 1.
  • FIG. 3 shows a single-piece set which has been folded along two lines to form a top sheet and two copy sheets. If desired further copy sheets can be added underneath.
  • This layer is a clay which has been treated with mineral acids. This substance acts as a pigment-forming "ingredient, which reacts with the spirodinaphthopyranes which are used as the colour formers,'the product of the reaction being coloured salts.
  • the colour receiving layer can have the following composition (parts, by weight).
  • methyl cellulose-and-polyvinyl alcohol instead of methyl cellulose-and-polyvinyl alcohol, other substances can be used as the binder, for example the known. water soluble binders such as starch, starch ether or carboxymethyl cellulose or the like. Furthermoreit is not. absolutely necessary to use a dispersion of polyvinyl acetate, instead of this there can for example be used a dispersionof acrylic acid ester or dispersions of mixed polymers. However the binder must be compatible with the acid treated clay.
  • acids in solid form for example amidosulphonic acid, oxalic acid, maleic acid, sulphosalicicacid or the like.
  • acids in solid form for example amidosulphonic acid, oxalic acid, maleic acid, sulphosalicicacid or the like.
  • the whole is mixed and ground and applied to the sheet of paper or foil using the coating devices customary in. the paper industry.
  • Substances which react as bases and which have proved in practice to be suitable as neutralisers are the aliphatic and aromatic amines, particularly amines derived from the fatty acids. 1
  • a neutralising mixture particularly suitable for application by the Flexobuch method, and which contains basic substances, has the. following composition (parts by weight): u
  • the mixture is a liquid, with a viscosity of approximately 240 cp., although the viscosity can if desired be higher or lower.
  • the neutralising substance can if desired be slightly .tinted using a spirits soluble dye.
