ABSTRACT:
Disclosed is a process for preparing ink millbase by use of a polymer blend of compatible polyesters and acrylic polymers. The polyesters are water-dispersible as a result of sulfonate groups on the polyester backbone. Use of the polymer blend results in an improvement in pigment particle size reduction during grinding.
