The resulting paint compositions produce unusual, but desirable, effects after the application of sufficient pressure to release a second colorant. Hence, the present invention includes methods for their use and manufacture.Type: ApplicationFiled: February 5, 2004Publication date: November 4, 2004Inventors: Kim D. Gooding, Yvette M. Swanson, Frances A. Amy, Christina Short

Patent number: 6786965Abstract: An aqueous organic pigment dispersion used to integrally color concrete and other building materials which includes: alkali metal silica particles as a binder; organic pigment; water; and dispersing agent in an amount effective to disperse the organic pigment and the binder in the water. A method for preparing the aqueous organic pigment dispersion includes (i) mixing, at 3,000 to 10,000 rpm, alkali metal silica particles; organic pigment; and dispersing agent, thereby forming a dispersion premix; (ii) milling the dispersion precursor in a mixer filled with glass beads for a period of time sufficient to reduce the particle size of the organic pigment to about 100 to about 300 nanometers, thereby forming a non-standardized dispersion; and (iii) standardizing the dispersion against a color standard by adding water.Type: GrantFiled: September 9, 2002Date of Patent: September 7, 2004Assignee: Sun Chemical CorporationInventors: Charles W. Perry, Donald C. Dulaney, James Moore
