  • Patent number: 11981819
    Abstract: The invention provides a disperse dye color paste for waterless dyeing, which comprises, by weight, 10%-40% of disperse dye filter cakes, 2%-35% of a dispersant, 5%-20% of a dyeing auxiliary, 0.1-0.5% of a surfactant, and 20%-88% of a solvent. The disperse dye color paste for waterless dyeing of the invention has a small particle size; and after waterless dyeing, a textile does not contain cleavable carcinogenic aromatic amine azo dyes, allergenic dyes, forbidden aromatic amine or bioactive substances. The disperse dye color paste for waterless dyeing of the invention can be stably stored for 6-12 months which is beneficial to the transportation of dyes and the production management of dyeing factories. Moreover, a dyeing effect featuring a high fixation rate is realized after the disperse dye color paste for waterless dyeing is applied to textiles.

  • Patent number: 6423127
    Abstract: A pseudo-plastic water based ink for a ball point pen which causes less scattering in a viscosity depending on a production lot and has good stability with the passage of time whatever coloring materials are used and which provides a good writing feeling and is excellent in cap-off resistance. The ink described above comprises at least a colorant, water and a polyglycerin isostearic acid ester represented by the following Formula (1): wherein n represents an integer of 1 to 8; R1 to R4 each independently and R5's, which may be the same or different, represent an isostearoyl group or a hydrogen atom; and the number of the isostearoyl group is 1 to 4.

  • Patent number: 6420449
    Abstract: A resin composition comprises a thermoplastic resin, a non-terpene-series higher fatty acid or a derivative thereof and a black pigment. As the higher fatty acid or derivative thereof, use can be made of, for example, a saturated higher fatty acid having about 12 to 30 carbon atoms or a metal salt thereof. As the thermoplastic resin, use can be made of, for example, an acrylic resin A and a styrenic resin B. As the black dye or pigment, use can be made of, for example, carbon black. The resin composition may contain a dye or pigment such as titanium oxide. A clearly defined white marking is developed on the above resin composition by laser irradiation.

  • Patent number: 6319309
    Abstract: The use of a polybasic acid and a volatile base, or a salt formed by the said acid and base, in an aqueous ink to increase the water-fastness of a water-soluble dye contained in the ink. Also claimed are novel aqueous inks containing an organic polybasic acid and a volatile base, a method of ink jet printing using the inks, a substrate printed with the inks and an ink jet printer cartridge containing the inks.

  • Patent number: 6265481
    Abstract: The invention relates to a printing ink which consists of pigments, an alkyd resin binder modified with fatty acids having an iodine number from 120 to 280 (g of I2/100 g), a phenolic resin-modified rosin binder and, if appropriate, further binders and further conventional constituents, such as lubricants, solvents, thickeners and thixotropic agents. The alkyd resin binder and the phenolic resin-modified rosin binder are present in proportions from 10 to 40% by weight and 60 to 90% by weight respectively, their sum giving 100% by weight. The alkyd resin has an acid number of Less than 11 and a hydroxyl number from 40 to 260 and has been prepared by reacting a) an unsaturated fatty acid having 6 to 20 carbon atoms or a mixture of such acids or their triglycerides with b) a polyol and c) a dicarboxylic acid.

  • Patent number: 6190444
    Abstract: Provided is a water-in-oil (W/O) emulsion ink for stencil printing which is less in change of viscosity with time and can give always stable prints. The emulsion ink contains a resinous component having a free carboxylic acid group or a higher fatty acid in the oil phase, and contains a divalent or trivalent metal salt and a monovalent metal salt having alkalinity in the water phase, whereby an interfacial layer of the emulsion is strengthened to stabilize the emulsion. The resinous component is preferably an alkyd resin, a rosin-modified phenolic resin, a maleic acid resin and a rosin. The monovalent metal salt or the divalent or trivalent metal salt is preferably contained in at least an amount equivalent to the free carboxylic acid of the resinous component and the higher fatty acid contained in the oil phase. The resinous component or the higher fatty acid is contained in an amount of 0.5-30% by weight based on the total amount of the emulsion ink.

  • Patent number: RE38952
    Abstract: A method of printing a liquid ink which is produced from a heat activated dye which is selected from a limited group of dyes which are capable of transfer at low energy. A printer which uses liquid ink, such as an ink jet printer, prints an image onto an intermediate substrate medium. The dyes contained in the ink are not substantially activated during the process of printing on to the medium. The image formed by the printed ink is transferred from the medium to a final substrate by the application of heat and pressure for a short period of time to activate the ink. The dye and dispersing/emulsifying agent(s) are selected from a limited group to produce an ink which permits thermal transfer at low energy, with the resulting image, as deposited on the final substrate, having an optical density of 1.0 or greater. Liquid ink is produced using heat activated dyes selected from a limited group of dyes that are capable of heat activation. The dyes are not substantially soluble in the liquid carrier, such as water.
