Abstract
A coating composition comprising: (a) a first polymeric coating binder, wherein the first polymeric coating binder comprises: (i) an aqueous polymer latex of a film forming carboxylated polymer; and (ii) a branched polyetheramine polyol dissolved in the aqueous phase of the polymer latex, wherein essentially all of the amino groups in the branched polyetheramine polyol are tertiary amine groups; and (b) a second polymeric coating binder, wherein the second polymeric coating binder comprises an acrylic binder; wherein the dry weight ratio of (a) to (b) is in the range of 70:30 to 20:80.
