Patent number: 6703443Abstract: A new and useful nonaqueous liquid pigment dispersion is provided which is easy to handle and produces thorough and effective colorations within target media, particularly as compared to standard solid pigments or high-viscosity liquid pigment dispersions. More specifically, the present invention relates to liquid pigment dispersions possessing viscosities of at most 5,000 centipoise at standard temperature and pressure. Such a low viscosity is obtained through the addition of relatively low amounts of aprotic viscosity modifiers possessing dipole moments of at between about 1.0 and 5.0, alternatively measured in terms of a flash point between about −20° C. and 180°, such as, most preferably cyclic carbonates.Type: GrantFiled: September 13, 2002Date of Patent: March 9, 2004Assignee: Milliken & CompanyInventors: Jusong Xia, Mark E. Ragsdale, Eric B. Stephens
