ABSTRACT The invention relates to a composition of matter comprising a blend of (A), from about 3% to about 98%, by weight, of a water-dilutable, nonionic polyether polyol resin having only carbon, hydrogen and oxygen atoms and optionally halogen atoms, having an average molecular weight between about 300 and about 2,000, having at least two alcoholic hydroxy groups, having from about 80% to about 10%, by weight, of hydrophobic moieties derived at least in part from aromatic or cycloaliphatic materials and correspondingly from about 20% to about 90%, by weight, of hydrophilic moieties consisting of -(CH2-CH2-O-) units; (B), correspondingly from about 97% to about 2%, by weight, solids basis, of an aqueous vinyl emulsion polymer having a particle size between about 600 .ANG. and 50,000 .ANG., containing from about 1% to about 10%. by weight, of functional reactive groups selected from the group consisting of hydroxy, carboxyl, amide, keto, methylol and alkoxymethyl groups and (C) from about 10% to about 85%, by weight, based on the total weight of (A) and (B), of a compatible aminoplast cross-linking agent having an average molecular weight not greater than about 1,500. The blends are useful in the coating field and in the manufacture of low pressure laminates, adhesives, moulding compounds and textile treating resins.
