Patent ID: 7728068

Claim:
A method of preparing a coating composition, the method comprising: providing a mixture comprising a water-dispersible polymer and a substantially non-irritating reactive diluent; wherein the water-dispersible polymer is prepared in the presence of the reactive diluent; wherein the mixture has a viscosity below 100,000 centipoise at processing temperatures; wherein the reactive diluent: includes a compound having a molecular weight of 350 grams/mole to 1000 grams/mole and having a viscosity at 25° C. of no greater than 2,000 cps; is substantially free of ethylene oxide moieties, propylene oxide moieties, and primary hydroxyl functionality; has an average ethylenically unsaturated functionality of at least 3.0; is present in an amount of 5 wt-% to 40 wt-%, based on the total weight of the reactive diluent and the water-dispersible polymer; and dispersing the mixture in water.
