Publication number: 20040206269Abstract: The present invention relates to methods of preparing modified organic colorant dispersions comprising the step of combining, in any order, i) an organic colorant; ii) an hydroxide reagent; and iii) an aqueous medium, to form a modified organic colorant dispersion. The methods further comprises a particle size reduction step. These steps can occur in either order. The organic colorant comprises at least one organic species having at least one carboxylic acid group. Modified organic colorants and uses of these modified organic colorants, including inkjet ink compositions, are also disclosed.Type: ApplicationFiled: April 16, 2003Publication date: October 21, 2004Inventor: Yuan Yu

Publication number: 20040194666Abstract: The present invention relates to pigment and coating compositions that are used to prepare pigmented coatings that exhibit geometric metamerism or metallic flop. The inventive pigment compositions comprise a small particle size pigment, at least one flop-enhancing agent, optionally one or more pigment property enhancing compounds. The flop-enhancing agent is selected from the group consisting of a halogenated copper phthalocyanines, indanthrones or carbazole dioxazines or mixtures thereof that are unsubstituted or substituted in the benzene rings by halogen, —NR1R2, C1-C10alkyl and —X—NR1′R2′, wherein R1 and R2 are independently hydrogen, C1-C10alkyl or —X—NR1′R2′, R1′ and R2′ are independently hydrogen or C1-C10alkyl, and X is C1-C10alkylene. The pigment property enhancing compounds may be a texture improving agent, a rheology improving agent, an antiflocculating compound and a dispersibility improving compound.Type: ApplicationFiled: March 29, 2004Publication date: October 7, 2004Inventor: Shivakumar Basalingappa Hendi

Patent number: 6784231Abstract: A pigment having weak dispersion force to be readily dispersed in a medium to be colored from which an excellent yellow image having superior transparency can be produced. The pigment includes a compound having the same chemical formula as C.I. Pigment Yellow 180. The BET specific surface area based on the nitrogen absorption process of the pigment is 20-100 m2/g, and the ratio of the absolute strength of X-ray diffraction at Bragg angle 2&thgr;=17.5°±0.2° to the absolute strength of X-ray diffraction at Bragg angle 2&thgr;=18.2°±0.2° of the pigment in a powder X-ray diffraction diagram using a CuK&agr; characteristic X-ray is less than 1.8/1.0. The present invention also provides a dispersion including the pigment and a thermoplastic resin having excellent transparency and color strength.Type: GrantFiled: March 19, 2002Date of Patent: August 31, 2004Assignee: Dainippon Ink and Chemicals, Inc.Inventors: Katsunori Shimada, Junko Sunouchi
