Publication number: 20090142492Abstract: The present invention relates to a water-based ink for ink-jet printing which is excellent in rubbing resistance upon printing on coated papers such as photographic papers, and also exhibits a high optical density upon printing on plain papers. The water-based ink for ink-jet printing according to the present invention includes a dispersion of a pigment wherein the number of pigment-containing polymer particles in the pigment dispersion which have a particle size of 0.57 ?m or more among the pigment-containing polymer particles contained in the pigment dispersion in the ink is 1.2×107/mL or less.Type: ApplicationFiled: August 10, 2006Publication date: June 4, 2009Applicant: KAO CORPORATION,Inventor: Kazunari Takemura

Publication number: 20090137706Abstract: The invention pertains to a novel, simpler dry-milling method for comminuting crude pigments (especially crude phthalocyanines) for use in publication gravure and packaging inks, wherein the crude pigment is dry-milled at relatively low temperature in combination with a resin and a pigment derivative, preferably further together with an extender and optionally an antioxidant. The invention also pertains to the thus obtained, new compositions, which are extraordinarily easily dispersible in aromatic solvents, and their use for the preparation of publication gravure or packaging inks or ink concentrates. Pigment dispersions obtained from the preferred compositions are also claimed.Type: ApplicationFiled: August 25, 2006Publication date: May 28, 2009Inventors: Thomas Healy, Ian Andrew Lambie

Publication number: 20090105377Abstract: A series of resins were synthesized using a range of bio-based materials to control the molecular architecture, and therefore the properties, of the inventive resins. The utility of these resins was demonstrated in the formulation of powder coatings, such as ?-hydroxy amide crosslinked and hybrid types. Generally, the bio-based resins flowed out on heating faster than conventional petrochemically-based resins, allowing the use of lower temperatures in the curing oven than is typically possible and a more active catalyst system, especially in the carboxylic acid-epoxy crosslinked hybrid coatings formulations.Type: ApplicationFiled: March 20, 2006Publication date: April 23, 2009Inventors: Bhima R.
