Patent number: 11987714Abstract: A usual ink composition can be expected to improve ink viscosity to a certain degree, but when used for a glycol ether-based ink recently required, an increase in viscosity in preparing the ink cannot be suppressed. In addition, there is unknown a copper phthalocyanine pigment composition which can satisfy both such an improvement in ink viscosity and resolubility as printability which is important for the glycol ether-based ink. In this situation, a problem to be solved by the present invention is to provide a copper phthalocyanine pigment composition having low viscosity and excellent resolubility in a glycol ether-based ink. It was found that when a copper phthalocyanine pigment is combined with a specified copper phthalocyanine acid derivative, a pigment composition having significantly low viscosity when formed into a glycol ether-based ink, and good familiarity with the ink can be produced, leading to the achievement of the present invention.Type: GrantFiled: June 13, 2019Date of Patent: May 21, 2024Assignee: DIC CORPORATIONInventors: Shingo Saitou, Taichi Hashiguchi

Patent number: 7569106Abstract: The invention relates to a method for producing an aqueous suspension of pure-phase ?-copper phtalocyanine blue pigment using an agitator ball mill. According to said method: a) in a preparatory step, a phthalocyanine crude blue is suspended by means of a dissolver in an aqueous medium, said aqueous medium containing in particular lipophilic substances, which are similar to binding agents and are compatible with the final application medium and crystalline-phase controlling and/or pigment-surface conditioning compounds; b) said aqueous suspension of the phthalocyanine crude blue is ground in an agitator ball mill to form a suspension of a ?-phtalocyanine blue pigment. The aqueous suspension thus obtained is characterized in that it contains a high-grade ?-phtalocyanine blue pigment for producing a conditioned ?-phtalocyanine blue pigment. The advantage is that said suspension can also be directly converted into a colour concentrate, in particular by means of a flushing and kneading method.Type: GrantFiled: June 16, 2005Date of Patent: August 4, 2009Assignee: Colour Ltd.Inventors: Rainer Heubach, Dieter Lieske

Patent number: 7550041Abstract: The invention pertains to a highly concentrated pigment comprising from 75 to 95% by weight, preferably from 78 to 95% by weight, most preferred from 80 to 95% by weight, based on the weight of the composition, of a pigment; from 0 to 20% by weight, preferably from 5 to 18% by weight, based on the weight of the composition, of a resin; the total of pigment and resin being from 85 to 98% by weight of the composition; and from 1 to 15% by weight, preferably from 2 to 15% by weight, most preferably from 5 to 15% by weight, based on the weight of the composition, of a C10-C18 alcohol, a liquid hydrocarbon having a boiling point higher than 80° C. at 105 Pa, or both a C10-C18 alcohol and a liquid hydrocarbon having a boiling point higher than 80° C. at 105 Pa. Also claimed are a process for its manufacture, comprising dry-milling, blending and kneading the components, and the use of the pigment concentrates for the preparation of a masterbatch, ink, coating, plastic material, toner or colour filter.Type: GrantFiled: October 24, 2005Date of Patent: June 23, 2009Assignee: Ciba Specialty Chemicals CorporationInventors: Thomas Healy, Lynda Cannon, Tracy Murray

Publication number: 20080271635Abstract: A process for the preparation of pigment compositions which give improved ink flow is provided which comprises treating the pigment, during the pigment synthesis, with a small amount of a long chain aliphatic amine. The pigment compositions obtained can be used for preparing millbase inks which due to their improved flow viscosity (rheology) at high pigmentation can be easily handled as well as flexibly formulated, e.g. a number of final printing inks for different ink applications can be manufactured from a single millbase in a very economical manner. The final inks are preferably used in packaging gravure printing processes.Type: ApplicationFiled: March 30, 2005Publication date: November 6, 2008Inventors: Stephen Haggata, Iain Frank Fraser, Stephen John Coughlin
