An aqueous coating composition having a pH of 6.0-10.0 and having a VOC of less than 0.24 kg/l (2.0 pounds/gallon) comprises 30% to 70% by weight of film-forming binder and correspondingly 70% to 30% by weight of an aqueous liquid carrier for the binder; wherein the binder comprises (a) 20% to 95% by weight, based on the weight of the binder, of a carbamate reaction product formed by the reaction of (1) an aliphatic polyisocyanate, (2) a monohydric alcohol, (3) a hydroxy functional aliphatic carboxylic acid and (4) a polyalkylene ether glycol having a number average molecular weight of 100 to 2,000; said reaction product being further reacted with an amine to provide a water-dispersible product; (b) 5% to 80% by weight, based on the weight of the binder, of a water-compatible alkylated melamine formaldehyde crosslinking agent. |
