Patent number: 7157505Abstract: Novel, rapidly drying, low volatile organic compound (VOC), minimal dot gain coatings, (including lithographic ink and varnish systems) are herein described. These systems dry sufficiently rapidly, that their usage eliminates ink drying speed as the rate limiting factor in most lithographic printing applications. In addition to providing enhanced drying rates as compared with their conventional counterparts, the rapid drying, low/no VOC lithographic coating systems of the instant invention can provide the user with significant improvement in dried film rub resistance.Type: GrantFiled: September 3, 2003Date of Patent: January 2, 2007Assignee: Vocfree, Inc.Inventor: Gerald Sugerman

Patent number: 7147801Abstract: Disclosed is an ink composition suitable for ink jet printing comprising a luminescent compound, a solvent, and an energy active compound, and optionally a non-luminescent colorant. The energy active compound, when exposed to energy, generates one or more active species that can react with the luminescent compound to alter one or more of the characteristics of the luminescent compound. The luminescent compound can be colored or colorless. Also disclosed is a method for marking substrates comprising providing a mark comprising a luminescent compound and an energy active compound. Further disclosed is a jet ink composition suitable for printing on substrates authentication or security marks which can be rendered unreadable. The luminescence of the mark is quenched and the visible color is changed when irradiated with a light.Type: GrantFiled: March 12, 2004Date of Patent: December 12, 2006Assignee: Videojet Technologies Inc.Inventors: Michael Kozee, Steven D. Looman, John P. Folkers

Patent number: 7135507Abstract: An ink including an aqueous dispersion of a metallic pigment and a film-forming resin, optionally together with one or more of a pH-adjusting agent, a color agent, a linking agent, an anti-settling agent, and a preservative, is disclosed. A marking instrument, particularly suitable for use with an ink according to the invention, and including a low-density reservoir for storing ink joined in capillary coupling relation to a porous nib, is also disclosed.Type: GrantFiled: November 18, 2002Date of Patent: November 14, 2006Assignee: Sanford, L.P.Inventor: Martin N. Sexton

Patent number: 7125447Abstract: An oil-based ink composition for ink jet recording of the present invention contains a colorant and at least 50% by weight of a mixed solvent made by mixing from 0.02 to 4 parts by weight of a lactone-type solvent with 1 part by weight of polyoxyethylene glycol dialkyl ether represented by the following general formula (1): R11—(OC2H4)n—OR12??General Formula (1) (wherein R11, R12 represent alkyl groups having from 1 to 3 carbon atoms and can be the same or different, and n is an integer from 2 to 4). The oil-based ink composition can be suitably used for printing on a polyvinyl chloride substrate and is excellent in all of print quality, printing stability, dry characteristics of printed matter, and storage stability of ink.Type: GrantFiled: July 16, 2003Date of Patent: October 24, 2006Assignees: The Intec Inc., Seiko Epson CorporationInventors: Yukio Sugita, Mitsuyoshi Tamura, Masahiro Nakamura, Seiji Mochizuki, Makoto Otsuki
