Definitions

  • a transfer sheet according to the invention comprises a light-transmitting temporary support sheet carrying a plurality of elements or points which together form a transferable pattern, coated with a coating of polymer containing microcapsules whose content liberated by rupture of the microcapsules under transfer pressure reacts with a top layer of pressure-sensitive adhesive to adhere and transfer the elements of pattern to a receptor surface.
  • the sheet carrying the pattern was cut out coat lely by means of scissors so as to form a piece which, when applied onto the surface to be shaded, would have parts overlapping the contours of said surface.
  • Said piece was applied with its adhesive surface against the surface of paper to be shaded and was adhered to the latter by the pressure-sensitive adhesive.
  • the draftsman followed the outer edge of the surface to be shaded and cut the patterned plastic piece.
  • the overlapping portions of the pattern applied were then removed This cutting operation required a great skill from the draftsman. It was necessary to estimate exactly the pressure to be applied on the sharp cutting stylus to pierce and cut out the patterned piece. Often, not only the patterned piece but also the underlying receptor surface of paper was cut out.
  • patterned sheets often are used in making architectural drafts. These drafts made on tracing paper or similar sheets are duplicated several times.
  • the duplicating machine comprises a cylinder of glass with which said patterned sheets are contacted. Said cylinder may reach temperatures up to 125C. It has often been found that even under temperatures below 100C, the pressure-sensitive adhesive coating of said sheets became less cohesive. For that reason, the pattern was detached from the paper and was either transferred onto the glass cylinder or moved on the paper.
  • One object of this invention is a new form of patterned sheet, wherein the pattern or any selected portion thereof can be transferred and adhered to a receptor surface under a pressure such as applied by means of a pencil or a spatula, the adhesion of the transferred pattern to the receptor surface, which may be of tracing paper or of similar material, being unaffected by contact at temperatures up to 150C.
  • a patterned sheet comprising a lighttransmitting temporary support having printed thereon a pattern of the kind described, the elements or points of the pattern being of a printing ink having two main components, at least the areas of said elements, and preferably the entire pattem-carrying surface of the support.
  • microcapsules being covered with a light-transmitting film made of one of the main components of the ink and containing dispersed microcapsules, said microcapsules containing a solvent of said light-transmitting film, said solvent having no solubilizing action on the temporary support and the ink of the pattern, said film being covered with a coating of pressure-sensitive adhesive whose components are miscible with said film and are soluble in the solvent of the microcapsules.
  • the light-transmitting support is transparent and characterized by a surface tension less than 36 dynes/cm and an insolubility at room temperature in the solvent contained in the microcapsules.
  • the temporary support may be polyethylene, tetrafluorethylene, polypropylene, polyethylene terephthalate, artificial parchment paper coated with silicone.
  • the ink printed on the temporary support to form the pattern comprises pigments.
  • the first main component is a polymer soluble in the solvent contained in the microcapsules and the second main component is a substance which reduces the solubility of the first main component in said solvent and may be a resin or another polymer.
  • the mixture of the two main components is adjusted in such a way that the action of the solvent may not dissolve the ink and can at most swell the ink so that each printed point or element keeps its shape and the pigments or dyestuffs may not escape from the binders by transfer.
  • the ink when the solvent contained in the microcapsules is toluene or xylene, the ink may be composed as follows:
  • Pigments Carbon black Soluble polymer (first main component): low viscosity ethylhydroxyethyl cellulose 40
  • Insoluble polymer second main component: nitrocellulose V2 second 60
  • Glycerophthalic resin with 52% of soy bean oil 58 cobalt naphthenate l and lead naphthenate I
  • the ink composition is adjusted so as to adhere moderately to the temporary support.
  • the film of light-transmitting unplastified polymer covering the printed pattern is of the same nature as the first main component of the ink of the pattern, namely the polymer soluble in the solvent of the microcapsules.
  • Microcapsules having a diameter less than microns are embedded in said light-transmitting polymer film and contain a solvent for said polymer.
  • the polymer film in which the microcapsules are embedded should be sheared at the places where the pressure is applied. Such effect was noted when the weight of microcapsules reaches at least 40% of the weight of the polymer.
  • the amount of solvent should be sufficient for dissolving or softening the polymer and the fine layer of pressure-sensitive adhesive superimposed thereto to a sufficient extent for obtaining a new combination of adhesive whose characteristics will be given hereafter.
  • This effect is obtained when the weight of microcapsules reaches at least 40% of the weight of the polymer and when the volume content of solvent of the microcapsules reaches at least 85% of the total volume of the microcapsules.
  • the solvent is, of course, selected depending on the polymer of said light-transmitting film.
  • said polymer when the solvent of the microcapsules is toluene, said polymer may be ethylhydroxyethylcellulose or chlorinated rubber; when the solvent is acetone, said polymer may be nitrocellulose.
  • Suitable microcapsules are described in Applicants US. Pat. No. 3,728,210.
  • the adhesion to the receptor surface appears not satisfactory everywhere. Indeed, when the microcapsules are ruptured, a more or less important part of the solvents is directly absorbed by the receptor surface so that the polymer is not always sufficiently softened and adheres very weakly.
  • the pressure-sensitive adhesive should be as follows: soluble in the solvent of the microcapsules; compatible with the polymer containing the microcapsules; applied as a layer whose thickness is not greater than one-third of the thickness of the light-transmitting polymer layer (this ratio does not take into account the diameter of the microcapsules contained in the polymer).
  • the rate of solubility of the pressuresensitive adhesive in the solvent of the microcapsules is less than the rate of solubility of the light-transmittin g polymer film which contains the microcapsules.
  • the instantaneous adhesion and the definitive adhesion of a pressure-sensitive adhesion are almost identical to one another and the cohesion of said adhesive does not change.
  • the light-transmitting polymer film and the pressuresensitive adhesive react with one another which causes an important modification of the adhesion of the adhesive after transfer.
  • the definitive adhesion becomes substantially greater than that of the original adhesive which is no longer pressure-sensitive.
  • the cohesion of the transformed adhesive is also increased to a higher level.
  • the transferred and transformed adhesive keeps its adhesion unaffected at temperatures up to C eg when the patterned film transferred on tracing paper is brought into contact with the hot cylinder of a draft-duplicating machine.
  • a support sheet 1 carries on its one surface called front surface, printed elements 2 of ink forming a pattern of shades, hatchings, hachures, crosshatches, grains, stipples, textile design. It is to be understood that these elements are not necessarily identical with one another and are distributed on the front surface of the support sheet.
  • the purpose of the transfer operation is to detach any selected portion of the pattern, thus comprising at least one and often a plurality of elements 2, from the support 1 and to transfer said portion of the pattern onto a receptor surface, eg. the area of a tracing paper on which shades are to be provided, by contacting said front surface with said receptor surface and applying a local pressure on the back surface of the support in the area where transfer is desired.
  • the front surface of the support 1 has a layer of light-transmitting polymer film 3 containing microcapsules 4.
  • the polymer of said layer 3 is similar to one of the main components of the elements 2 so that the layer 3 and the elements 2 adhere strongly to one another.
  • the materials of the elements 2 and layer 3 are selected for adhering moderately to the support.
  • a layer 5 of the pressure-sensitive adhesive covers the layer 3 of polymer and forms thus the top layer of the transfer sheet. When a local transfer pressure is applied as described above, the transferable part becomes adhered to the receptor surface within the limits of the area of pressure.
  • the microcapsules rupture, their solvent content permits the transferable part to shear along the limits of the area of pressure and within said limits causes the pressuresensitive adhesive to interact with the polymer layer 3 to make a stronger adhesive as described above.
  • the transferable part is separated from the support 1 in said area of pressure so that the pattern is transferred to the extent desired.
  • Pigments Carbon black Polymers: Ethylhydroxyethyk cellulose 60 Nitrocellulose V2 second 30 Solvents: Ethylglycol 170 Butylglycol 100 Xylene 30 After drying of the ink, the temporary ,support and the ink elements of pattern are covered with a transparent coating composed as follows:
  • a patterned transfer sheet carrying on one surface thereof a plurality of elements or points which together form patterns, any selected portion of one or more of said patterns, being transferable and adherable to a receptor surface, comprising 1. a light-transmitting temporary support, carrying on its surface,
  • an unplasticized transferable film comprising:
  • a pigmented layer forming the elements or points of the patterns and being composed of a printing ink with two main components
  • a light-transmitting layer formed of one of the main components of said ink and containing dispersed microcapsules covering at least the portion of the pattern carrying surface of said temporary support, said microcapsules containing a solvent for said light-transmitting film with said solvent having at the very most a swelling action on said printing ink and no solubilizing action on the tempo rary support, and
  • a transfer sheetas inclaim l in which the first main component of the ink is a polymer soluble in the solvent contained in the microcapsules and the second main component of the ink is a substance which reduces the solubility of the first main component in said solvent, the ratio between the first and second main component being such that said solvent contained in the microcapsules cannot, dissolve the ink.
  • an unplasticized transferable film comprising:
  • a pigmented layer forming the elements or points of the patterns and being composed of a printing ink with two main components
  • a light-transmitting layer formed of one of the main components of said ink and containing dispersed microcapsules covering at least the portion of the pattern carrying surface of said temporary support, said microcapsules containing a solvent for said light-transmitting film with said solvent having at the very most a swelling action on said printing ink and no solubilizing action on the temporary support, and
