| 106310280 | With pigment | 9 |
| 20080282931 | Pigment Compositions for Oil-Based Lithographic Printing Ink System - Pigment compositions for oil-based lithographic printing ink systems are provided which comprise as colourant besides an organic pigment an organic dyestuff soluble in an organic solvent (solvent dye). The printing inks prepared from these pigment compositions show outstanding improvements in colour strength combined with improvements in both gloss and transparency of the prints obtained. | 11-20-2008 |
| 20110067597 | MIXED PHTHALOCYANINE AND NAPHTHALOCYANINE DYES FOR NEAR-INFRARED APPLICATIONS - Mixed phthalocyanine and naphthalocyanine water-soluble dyes with near-infrared absorption comprise four isoindole units linked together in a large ring to form a phthalocyanine macrocycle. At least one benzene ring is linked to an isoindole unit and at least one naphthalene ring is linked to another isoindole unit. The remaining two isoindole units each have a benzene ring or a naphthalene ring linked thereto, in any combination. A metal atom is optionally complexed to the phthalocyanine macrocycle. | 03-24-2011 |
| 20110073005 | POLYPHENYLATED PHTHALOCYANINES WITH NEAR-INFRARED ABSORPTION - Polyphenylated phthalocyanine water-soluble dyes with near-infrared absorption comprise four isoindole units linked together in a large ring to form a phthalocyanine macrocycle, with either four anthracenyl groups or four naphthacenyl groups each linked to an isoindole, and a metal atom optionally complexed to the phthalocyanine macrocycle. | 03-31-2011 |
| 20110308427 | PIGMENTED INKJET INK COMPRISING A BLEED CONTROL AGENT - The present invention provides an ink for inkjet printing. The ink contains an aqueous vehicle, a self-dispersing pigment and an effective amount of a biopolymer as a bleed control agent. The ink exhibits reduced intercolor bleed when printed, for example, on plain paper. | 12-22-2011 |
| 20120137927 | PHTHALOCYANINES AND NAPHTHALOCYANINES WITH NEAR-IR ABSORPTIONS FOR INKJET INKS - A water-soluble phthalocyanine dye or naphthalocyanine dye with near-infrared absorption comprises at least one complexed unit. Each unit comprises a phthalocyanine or a naphthalocyanine moiety and, optionally, a metal atom complexed thereto and, if present, having a valency of from 1 to 5, with two valencies complexed to the phthalocynanine ring or the naphthalocyanine ring. Each unit has two linker moieties on opposite sides or adjacent sides of the unit, wherein water-soluble groups are present on at least one of the linkers, on the metal atom, and optionally on the phthalocyanine or naphthalocyanine moiety. | 06-07-2012 |
| 20120137928 | PHTHALOCYANINES AND NAPHTHALOCYANINES WITH NEAR-IR ABSORPTIONS FOR INKJET INKS - A water-soluble phthalocyanine dye or naphthalocyanine dye with near-infrared absorption comprises at least one complexed unit. Each unit comprises a phthalocyanine or a naphthalocyanine moiety and a metal atom complexed thereto and having a valency of at least three, with two valencies complexed to the phthalocynanine ring or the naphthalocyanine ring, each unit joined to another through a fused ring, at least one valency attached to water-soluble axial ligands. The dyes to may be employed in inkjet inks in conjunction with colorants. | 06-07-2012 |
| 20130087070 | WATER-BASED INK COMPOSITION FOR BALLPOINT PEN - Provided is a novel ink composition for a ballpoint pen such that the ink composition combines the strength of water-based ink for ballpoint pens and oil-based ink for ballpoint pens. Specifically provided is a water-based ink composition for ballpoint pens, wherein an oily phase containing an oily solution obtained by dissolving a dye in an organic solvent is contained, as an oil-in-water emulsion, in an aqueous phase comprising a pigment dispersant. | 04-11-2013 |
| 20130284055 | Rapidly crystallizing phase change inks and methods for forming the same - A solid ink composition suitable for ink jet printing, including printing on coated paper substrates. In embodiments, the solid ink composition comprises both a crystalline compound and an amorphous compound, and optionally, in combination, an organic pigment, which provides for a robust, rapid crystallization ink composition. | 10-31-2013 |
| 20150040797 | INK COMPOSITION FOR WATER-BASED BALLPOINT PEN - To provide an ink composition for a water-based ballpoint pen, having properties such as excellent writing stability in which writing failure such as starving does not occur. | 02-12-2015 |
