  • Patent number: 6576591
    Abstract: A coding scheme to identify the connections an optical fiber is to form in an optical assembly is provided. The coding scheme consists of a series of colors, typically four, provided along the fiber length. The combination of colors identifies the connection the fiber is to form. Colors are transferred to the optical fiber by sublimation of the dye at a relatively low temperature. The sublimed dye then diffuses into the outer coating of the optical fiber.

  • Patent number: 5308426
    Abstract: A process for decoration of the surfaces of an object by sublimation of ink consisting in; using as a sublimable ink support a material which is sufficiently extensible and air-permeable so as to conform to the shape of the object to be decorated without adversely effecting the decoration to be sublimated, enveloping the object in the ink support, and placing the enveloped object in a vacuum machine which is introduced into a heated space to thereby cause transfer of the decoration to the object.

  • Patent number: 5142722
    Abstract: A process for applying images by transfer printing disperse dyes onto furniture end pieces, especially end pieces for use in juvenile furniture. In one preferred embodiment the end piece board is first coated with a pigmented non-polyester base coat which is applied with rollers and conventionally cured. The board is then coated with a 100% polyester clear top coat which is also applied with rollers and UV cured. In a second preferred embodiment the board is coated with a pigmented polyester base coat which is either sprayed or roll coated and which may be either conventionally or UV cured. Finally a sublimation decal is transfer printed into the polyester coating using a press having heated platens and operated at about 400.degree. F. and at between 8-30 psi for between 20-40 seconds. For larger boards, a silicone pad may be attached to the upper platen of the heat press adjacent to the surface of the platen which contacts the transfer printing decal to improve image transfer for uneven presses.

  • Patent number: 4664672
    Abstract: A process for transfer printing onto solid substrates made of plastics or having a surface layer of varnish or plastic is described. According to the invention described a sheet dye carrier at a temperature suitable for dye transfer is pressed to a preferably preheated surface and/or to a limited area of the surface to be printed by means of superatmospheric gas pressure, in particular by means of a flowing gas. Additionally the surface to be printed is maintained at a temperature below the thermoplastic range during the transfer process.

  • Patent number: 4615938
    Abstract: Dye-receiving sheets for thermal recording which comprise a support and a dye-developing or receiving layer formed on the support. The layer is made of a composition comprising a dispersion of inorganic fine particles uniformly dispersed throughout a binder of a mixture comprising a first resin having good dye receptivity or good affinity for dyes and a second resin immiscible with the first resin. The binder mixture of two different types of resins allows microscopic interstices to exist at or along boundaries of the resins, through which interstices dye molecules penetrate and chemically combine with and/or adsorb on active sites of the inorganic particles and the first resin.

  • Patent number: 4523922
    Abstract: The viscosity of aqueous printing inks for gravure printing is adjusted by means of partially organophilic gels which contain plastics mixtures of at least one polymer swelling in water and at least one polymer not swelling in water or to an insignificant extent only, in a solvent mixture of at least two hydrophilic organic hydroxy compounds and one hydrophobic organic hydroxy compound. The printing inks prepared with the aid of the thickener mixtures of the invention contain up to 90% of water, and can be handled as textile printing pastes.Gravure printing inks on the basis of such plastics gels containing disperse dyestuffs are suitable for the manufacture of transfer printing paper sheets. Since the thickening system adjusting the viscosity contains aqueous alcohols, if any, and no solvents as usual in transfer printing inks, no special measures have to be taken with respect to flammability and explosion risks.

  • Patent number: 4367071
    Abstract: An ink composition for heat transfer printing comprising at least one of carbinol bases of basic dyes or their derivatives, a strong base, a binder and a solvent for dissolving the binder. This ink composition is excellent in storage stability because it contains a carbinol base of a basic dye or its derivative in isolated form as a coloring agent along with a strong base. By using this ink composition, a transfer sheet having high storage stability can be obtained.

  • Patent number: 4357189
    Abstract: A porous material is printed with a sublimable dyestuff designed to achieve substantial pattern depth penetration. After the porous fabric has been printed it is consolidated by compression and fusion to a desired degree. This then provides a product which has a through color printed effect.

  • Patent number: 4242092
    Abstract: The color printing of textile webs or structures such as carpets and tiles which are tufted or non-woven wherein the color is sublimatic dyestuff carried by an air permeable printing foil and this is placed over the textile structure with the dyestuff facing the textile structure. Heat is applied to vaporize the dyestuff and a pressure differential across the textile structure causes an air flow through the sheet structure and printing foil to affect penetration of the dye vapor into the structure. The dyestuff deposits on the textile fibres and filaments in the pattern it appeared on the printing foil. The said pressure differential is preferably produced by creating a vacuum at the side of the sheet structure opposite the printing foil.

  • Patent number: 4231743
    Abstract: A process is disclosed for the making of a decorative carpet through the use of sublimable dyes. A shading effect is secured through the use of air flow control sheets that affect the flow of air through a transfer sheet and a carpet product adjacent thereto. By lessening air flow, the intensity of dye being transferred is also lessened so that shades of a certain color can be secured.
