  • Patent number: 9374907
    Abstract: A method of forming a printed pattern on a substrate includes printing a pattern onto the substrate with a conductive ink including a conductive material, a thermoplastic binder and a solvent, curing the printed pattern, and fusing the printed pattern by feeding the printed pattern through a fusing system operated at a temperature of about 20° C. to about 130° C. above the glass transition temperature of the thermoplastic binder and at least 120° C. at a minimum, a pressure of from about 50 psi to about 1500 psi, and a feed rate through the fusing system of about 1 m/min to about 100 m/min. The method may be done continuously. The method improves the sheet resistivity of the printed ink.

    Abstract: A liquid ink composition and a method for producing the same, wherein the liquid ink composition includes a colorant, a charge control agent to regulate electrostatic properties of the colorant, and an organosol to disperse and bind the colorant and the charge control agent. The colorant may be coated with a thermoplastic resin to improve binding with the organosol. By coating the colorant with the thermoplastic resin, the affinity of the colorant for the organosol is facilitated, increasing a size of particles in the liquid ink composition, so that the control of the particles improves the image quality, and micro particles of the carbon black pigment alone do not substantially exist in the printer to prevent printing on a non-image area, thus producing a clear printed image and preventing contamination of other parts in the printer during printing.

  • Publication number: 20020083865
    Abstract: A water-based lithographic ink composition is described, and contains water, a resin-bonded pigment; a nonionic surfactant, a rewetting agent, and a polymerizable surfactant. The nonionic surfactant is present in an amount such that the dynamic surface tension of the total composition is about 20 to about 40 dynes/cm. The polymerizable surfactant is present in an amount of about 0.5% by weight to about 2% by weight of the composition. The ink composition may also contain other, conventional ink component, as desired.

  • Patent number: 6413305
    Abstract: A thermochromic ink composition is provided for use on security documents such as checks which provides a reversible color change in response to heat. The ink composition includes a thermochromic aqueous slurry and an ink vehicle comprising either a phenolic modified rosin and a compatible oil, a styrene maleic anhydride resin and a glycol, or an acrylic resin varnish. The ink composition is printed on at least a portion of a substrate using letterpress printing methods and provides enhanced adhesion to toner when applied to areas of a substrate which are subsequently printed with a non-impact printing device such as a laser printer.

  • 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.
