Definitions

  • a multicolor transfer medium is provided by a process which comprises making a first matrix material by mixing a fluid transfer ink of a first color with a solution of a film forming polymer in a solvent for the polymer, coating the resulting dispersion on a first substrate and evaporating the solvent to form the matrix material of a first color.
  • a matrix material of a second color is formed in an identical manner utilizing a fluid transfer ink of a second color.
  • the two substrates supporting the matrix materials are then placed in adjacent edge aligned relationship to one another on a third substrate which has been coated with a fugitive adhesive and a polymer is thereafter back coated over the two matrix materials to seal them together.
  • the resulting unitary multicolored transfer medium is then stripped from the substrates and slit, if required, to a desired width.
  • This invention relates broadly to a novel transfer medium useful as carbon paper, typewriter ribbon or the like. More specifically the present invention is directed to reusable multicolored plastic transfer elements and to methods for making such transfer elements.
  • Multicolored transfer elements now in common usage may be generally classified in the following two broad categories: Ink impregnated woven fabrics and single use carbon paper and carbon film materials.
  • the multicolored woven fabric is generally produced by passing the fabric over a split inking roller having the various colored inks located thereon in a manner to transfer the ink from the roller to the' fabric.
  • Great care must be taken to insure proper alignment of the fabric with the roller to insure ribbon uniformity.
  • great care must be taken in the selection of the inks utilized to insure that they have proper thixotropy and bleed characteristics.
  • the impregnated woven fabric ribbons are characterized by lack of conformity of the fabric to the type face under impact and this results in a low quality transfer. This low quality transfer is further aggravated by the lack of dyestuif that is characteristic of fabric two color ribbon inks (the lack of dyestuif insuring ink separation).
  • a third type of transfer medium has been suggested in the prior art: reusable porous polymer films.
  • An example of such a medium is fully described in US. Pat. 3,413,- 184 entitled Transfer Medium and Method for Making Same.
  • Such a medium comprises a solid, continuous porous matrix containing globules of a liquid or jelled ink within the pores.
  • inks may be utilized in conjunction with such a medium, the only constraint on the ink being that it is relatively insoluble in low concentration of the solvent in which the polymer and ink are dispersed during the manufacturing process.
  • the resulting material is of a thin caliper, but yet the spongy like construction of the thin caliper material allows it to be used over and over. Since the ink and resin are dispersed in a liquid-form during the manufacturing process, casting of more than one color ink and matrix simultaneously results in intermixing and contamination of one colored matrix with another. Further, it is not possible to manufacture a multicolor polymer film utilizing conventional multicolor fabric ribbon inking or those multicolor carbon film material techniques which require thermal bonding.
  • a multicolor medium could be produced by coupling two matrix materials to a substrate layer in aligned relation utilizing the adhesive approach heretofore taught in the formation of carbon films of multiple colors
  • the resultant product would be of thicker caliper and great care would have to be taken in selecting a proper substrate medium and adhesive which would co-act with the thus coupled transfer medium in a manner to produce legible and consistant graphic symbols when utilized in an environment such as a typewriter. That is, the selection of the adhesive and substrate vary the transfer characteristics of the medium and unless great care is utilized in selecting these components, a ribbon having the attributes of the polymer matrix would not result.
  • the transfer medium of the present invention is formed during three separate operations.
  • a matrix material of a first color having varying porosity throughout horizontal zones thereof is formed on a first temporary substrate in a manner similar to that described in US. Pat. 3,413,184.
  • a second matrix material of a second color is formed on a second substrate in an analogous manner.
  • the two substrates supporting the matrix materials are then placed in edge aligned relation on a sup port substrate containing a liquid adhesive.
  • the liquid adhesive facilitates initial lateral movement of the material carrying substrates in order to effect the precise alignment of the substrates and also couples them to the support substrate.
  • a back coating of the polymer is applied over the two matrix materials and the exposed portions of the substrates.
  • the back coating is continuous with the polymer phase of the matrix materials and forms a barrier between the discrete colored strips.
  • the discrete separation between the colored strips and the barrier prevent bleeding of inks of one color strip to the other.
  • the liquid adhesive prevents excessive penetration of the polymer to the substrate.
  • the transfer medium is then stripped from the substrates and the medium may be slit to desired widths.
  • FIG. 1 is a schematic side elevational view of a system or apparatus for carrying out the process of the present invention.
  • FIGS. 2a, 2b, 2c, 2d, and 2e are edge views of the transfer medium as it is manufactured.
  • the continuous porous matrix of the transfer medium can be made of a suitable synthetic polymer which includes the following: polyamide resins such as nylon, polyurethane, polycarbonates, polyethylene, polypropylene, polyvinyl acetate, polyvinyl chloride, vinyl chloride, acrylonitrile butadiene, cellulose acetate butyrate and cellulose acetate.
  • polyamide resins such as nylon, polyurethane, polycarbonates, polyethylene, polypropylene, polyvinyl acetate, polyvinyl chloride, vinyl chloride, acrylonitrile butadiene, cellulose acetate butyrate and cellulose acetate.
  • Other synthetic resins or mixtures of synthetic and natural resins capable of forming thin, self supporting porous matrices may be substituted for the foregoing without departing from the scope of the invention.
  • the exact composition of the inks incorporated in the pores of the polymer matrix is not critical and may be in the form of either a fluid ink or a jellied ink.
  • One requirement of the ink is that it not be soluble in the polymer matrix.
  • An additional requirement is that it is non volatile at temperatures used to form the matrix.
  • most oil base dye soluble inks, Water base dye soluble inks and pigmented thixotropic inks with and without dyes could be used.
  • the polymer is dissolved in a volatile solvent and the ink is distributed in the polymer solution. This solution is then coated on a temporary heat stable substrate such as a paper web or an endless belt of Mylar. The solvent is then evaporated, and during this action, a relatively high concentration of plastic is obtained at the upper surface and a higher concentration of ink is obtained at the lower surface adjacent to the temporary substrate.
  • a plurality of polymer matrix transfer materials each of dilfering colors are formed as described above on a like plurality of temporary substrates.
  • the substrate supported matrix materials are then slit to required widths without peeling them from their substrates.
  • a temporary heat stable support substrate is then prepared by coating it with a film of liquid adhesive.
  • the adhesive may be a fugitive adhesive such as a solution of water and wetting agent (e.g. polyethylene glycol) or isopropanol and glycerin or a permanent adhesive such as ethylene acetate copolymer or acrylonitrile butadiene or a hot melt adhesive (e.g. wax blends).
  • a plurality of slit matrix material supporting substrates are then placed in edge aligned relationship on the adhesive layer of the support substrate.
  • the film of adhesive facilitates initial alignment of the matrix material supporting substrates with respect to one another permitting lateral movement of these substrates over the support substrate.
  • a fugitive adhesive When a fugitive adhesive is used it is partially evaporated and absorbed causing the matrix supporting substrates to become temporarily but firmly adhered to the support substrate.
  • Conventional adhesives and hot melt adhesives solidify to permanently join the substrates. With the substrates thus coupled, movement of the substrates with respect to one another is prevented during subsequent handling and coating operations.
  • a back coating of a polymer material preferably of the same polymer material utilized to form the matrix materials is dissolved in a solvent and applied over the matrix materials and the exposed portions of the substrates.
  • the applied polymer penetrates between the matrix materials to form. a minute barrier layer between the substrate supported matrix materials.
  • the adhesive located on the support substrate prevents excessive penetration of the support substrate by the polymer material.
  • the solvent is evaporated leaving an integral solvent bonded polymer film on the top surface of and bet-ween the matrix materials.
  • the matrix materials and the polymer film bonded thereto are then peeled from the temporary substrates resulting in a unitary multicolor transfer medium. The edges of the transfer medium can thereafter be slit to obtain a medium of a desired Width and to remove excess polymer material.
  • the back coated matrix materials may be stripped from the substrates leaving the excess back coated polymer material with the substrates resulting in a unitary transfer medium having clearly defined straight edges which require no further slitting operation.
  • a black color ink and filler dispersed in a nylonethyl alcohol solution is prepared by following steps (1) through (4) of Example I of the afore referenced US. Pat. 3,418,184. This mixture is coated onto a temporary 1 mil thick Mylar substrate and dried in the exact manner described in the afore referenced patent resulting in a one mil thick black matrix material film layer on the Mylar substrate. The ink distribution within the matrix is non uniform as described in the patent. The substrate and film are then wound onto a take up reel.
  • a red color ink and filler dispersed in a nylonsolvent solution is prepared in the following manner:
  • step (2a) One part by weight of nylon is dissolved in a suflicient quantity of sol-vent mixture prepared in step (2a) to produce a solution containing 12% nylon and 88% solvent.
  • the solution is obtained by mixing the nylon and solvent mixture in a Cowles dissolver at a temperature of 140 F. Stirring expedites the solution.
  • step 20 Five parts by weight of the ink prepared in step 20 is then slowly added to the mixture of filler and the nylonsolvent solution prepared in step 2d under high speed agitation in a Cowles dissolver, until complete distribution of the ink and filler in the nylon solution is obtained.
  • step 22 The mixture obtained in step 22 is coated onto a temporary 1 mil thick Mylar substrate and dried in the exact manner described in the afore-referenced patent resulting in a one mil thick red matrix material film layer on the Mylar substrate.
  • the substrate and film are wound onto a take up reel.
  • step 2 A blue-black color ink and filler dispersed in a nylon-solvent solution is prepared as in step 2 except the following ink ingredients are utilized in place of those specified in step 20.
  • the mixture is coated as in steps 1 and 2 resulting in a one mil thick blue-black matrix material film layer on a 1 mil Mylar substrate.
  • the substrate and film are wound onto a take up reel.
  • All substrate supported matrix material prepared in roll form in steps 1-3 is slit to required ribbon width and rewound in roll form.
  • the material prepared by step 1 is slit to a width of 0.4 and the materials prepared by steps 2 and 3 are slit to a width of 0.021".
  • Step 4 all cut matrix material in roll form (Step 4) is mounted on shafts 11 and 13.
  • the matrix materials 15, 17 are staggered with respect to each other on the two shafts and placed in the required order of the finished transfer element, the wider material being located intermediate the narrow material.
  • a 2 mil Mylar substrate 19 is mounted on supply shaft 21.
  • the water-polyethylene glycol solution (Step 5) is placed in tank 23 and wiped onto the 2 mil Mylar substrate to form a 0.1 mil film on the substrate.
  • the substrate is then passed over the guide roller 24 with the film side up.
  • the matrix materials are taken from their respective supply rolls and are edge aligned as they pass through the spring mounted concave guide pulley 25.
  • the Mylar substrate side of the matrix materials is then located over the 2 mil Mylar substrate at the guide roller 24.
  • the water-polyethylene glycol film initially facilitates lateral movement of the matrix supporting Mylar substrates to effect perfect alignment.
  • the materials are then passed through a Gardner applicator 27 containing the nylonethyl alcohol mixture (step 6) which deposits 0.5 to 1.0 mil dry nylon on the back surface of the matrix materials.
  • the back-coated matrix materials are then passed through a drying oven where an average temperature of 180 F. is maintained to disperse the solvent from the backcoated nylon and form an integral solvent bonded nylon film on the top surface of the nylon matrix materials.
  • the unitary back coated matrix materials are then stripped from the one mil thick support substrates and the two mil support substrate which is attached to the one mil substrates and are wound on reel 31.
  • the one mil substrates are separated from the two mil substrate (the fugitive adhesive bond is broken) and wound on reel 33.
