Patent number: 8323525Abstract: A resin containing a liquid pigment dispersion is disclosed. The dispersion comprises a pigment dispersed in a blend of two or more active hydrogen-containing materials that together have a freezing point that is room temperature or below. The pigment remains dispersed in the blend, even if the dispersion is subjected to freezing and thawing. A curative blend comprising at least two active hydrogen-containing materials, which is liquid at room temperature, is also disclosed. The dispersions and curative blends of the present invention can be solvent-free. Resins and prepolymers comprising the curative blends of the invention, either pigmented or unpigmented, are also disclosed.Type: GrantFiled: December 21, 2011Date of Patent: December 4, 2012Assignee: PPG Industries Ohio, Inc.Inventors: Kelly J.
