Patent number: 8623126Abstract: An inkjet ink composition comprising: (a) water; (b) dispersed pigment particles; and (c) at least one humectant; wherein the pigment particles are present from about 4.5% by mass to about 10% by mass, and the pigment particles have a mass weighted mean Stoke's diameter of from about 35 nm to about 70 nm wherein the Stoke's diameter is determined by differential centrifugal sedimentation of the particles through a fluid in a disc centrifuge. The present invention employs specified sedimentation particle sizing criteria for selection of appropriate pigment particle sizes at high pigment concentrations to obtain improved ink performance. Further embodiments of the invention also demonstrate that the criticality of humectant types and levels employed in an ink can also become much more important at high pigment loading in order to obtain desired performance.Type: GrantFiled: June 29, 2012Date of Patent: January 7, 2014Assignee: Eastman Kodak CompanyInventors: Thomas B.

Publication number: 20140000478Abstract: A process for modifying the surface of a carbon black by contacting said carbon black with a conjugated diimine compound. The conjugated diimine compound may comprise various substituents to provide the carbon black with desired corresponding properties, such as groups to impart increased hydrophilicity and self-dispersibility to the carbon black. Other embodiments relate to novel carbon black products, which may be prepared according to a process of the invention. The carbon black products may be used in the same applications as conventional carbon blacks. Such uses include, but are not limited to, plastic compositions, aqueous inks, aqueous coatings, rubber compositions, paper compositions, and textile compositions. In a specific embodiment, the resulting surface modified carbon black is employed as a pigment in an aqueous inkjet ink composition.Type: ApplicationFiled: June 27, 2012Publication date: January 2, 2014Inventors: Steven Evans, Ellen J.
