Abstract

Disclosed is the use of a carbon black dispersion variant CAB-0-JETTM 300 for improving wet smear, dry smear, and the increase in density of a carbon black pigmented ink while maintaining intercolor bleed measurements that are within the same range of the current inks used in Thermal Ink Jet (TIJ) printers. The improved CAB-0-JETTM carbon black dispersion benefits from an additional processing step where the functional carboxylic acid groups cover more surface area on pigment.
