Claim 1
Independent Claim
121 words
A composition of matter comprising a water-dilutable blend of (A) from about 10% to about 90% of a water-dilutable, polyether polyol resin, containing only carbon, hydrogen and oxygen atoms and optionally a halogen atom, having an average molecular weight between about 250 and about 2,000, having at least two alcoholic hydroxy groups, having from about 80% to about 20%, by weight, of hydrophobic moieties derived at least in part from aromatic or cycloaliphatic materials and correspondingly from about 20% to about 80%, by weight, of hydrophilic moieties consisting of --(CH 2 CH 2 --O--) units and (B) correspondingly from about 90% to about 10%, by weight, of a compatible aminoplast cross-linking agent having an average molecular weight not greater than 1,000.
Claim 2
Dependent Claim
121 words
A composition of matter comprising a water-dilutable blend of (A) from about 10% to about 90% of a water-dilutable, polyether polyol resin, containing only carbon, hydrogen and oxygen atoms and optionally a halogen atom, having an average molecular weight between about 250 and about 2,000, having at least two alcoholic hydroxy groups, having from about 80% to about 20%, by weight, of hydrophobic moieties derived at least in part from aromatic or cycloaliphatic materials and correspondingly from about 20% to about 80%, by weight, of hydrophilic moieties consisting of --(CH 2 CH 2 --O--) units and (B) correspondingly from about 90% to about 10%, by weight, of a compatible aminoplast cross-linking agent having an average molecular weight not greater than 1,000.
