Abstract
A pigment grind composition contains pigment, water dispersible acrylic polymer and a reactive diluent. The reactive diluent has a number average molecular weight of between about 200 and about 2500 and is selected from polyalkylene glycols, polyalkylene glycol ethers, glycol ether formals or mixtures of these. The pigment grind composition has a volatile organic content of less than two pounds per gallon.
