Patent ID: 7605209

Claim:
A method of preparing a coating composition, the method comprising: providing a mixture comprising a water-dispersible polymer and a 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, and further wherein the reactive diluent 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 includes a compound having a molecular weight of 350 grams/mole to 1000 grams/mole and, is substantially free of ethylene oxide and propylene oxide moieties and has an OH-functionality of no more than 30 milliequivalents KOH/gram, with the proviso that the reactive diluent does not include pentaerythritol tetraacrylate; and dispersing the mixture in water.
