Patent number: 6221142Abstract: The ink of the invention comprises a vehicle and a colorant. The colorant is a water-insoluble pigment that has been chemically modified to be water dispersable by addition of functional groups to the surface of the pigment resulting in water soluble colorant particles. The performance of these pigments is improved by the addition of specific functional groups which provide improved black to color bleed control and high waterfastness.Type: GrantFiled: October 8, 1999Date of Patent: April 24, 2001Assignee: Hewlett-Packard CompanyInventors: Patricia A. Wang, David J. Halko, Ronald J. Gambale, Robert M. Amici

Patent number: 6042643Abstract: Processes for preparing a carbon black product having an organic group attached to the carbon black. In one process at least one diazonium salt reacts with a carbon black in the absence of an externally applied electric current sufficient to reduce the diazonium salt. In another process at least one diazonium salt reacts with a carbon black in a protic reaction medium. Carbon black products which may be prepared according to process of the invention are described as well as uses of such carbon black products in plastic compositions, rubber compositions, paper compositions, and textile compositions.Type: GrantFiled: June 26, 1998Date of Patent: March 28, 2000Assignee: Cabot CorporationInventors: James A.
