Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
187 words
A composition of matter comprising a blend of (A), from about 3 to about 98%, by weight, of a water-dilutable, non-ionic 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 --(CH 2 --CH 2 --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 A and 50,000 A, containing from about 1% to about 10%, by weight, of functional reactive groups selected from the group consisting of hydroxy, carboxyl, amide, keto, metylol 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.
Claim 2
Dependent Claim
187 words
A composition of matter comprising a blend of (A), from about 3 to about 98%, by weight, of a water-dilutable, non-ionic 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 --(CH 2 --CH 2 --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 A and 50,000 A, containing from about 1% to about 10%, by weight, of functional reactive groups selected from the group consisting of hydroxy, carboxyl, amide, keto, metylol 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.
