Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
246 words
A composition of matter comprising (1) a blend of an aqueous melamine/formaldehyde resin solution and from about 2 to about 20%, by weight, based on the solids weight of said resin, of an ethylene glycol having a molecular weight of from about 62 to about 2100, or (2) an aqueous solution of the resinuous reaction product of (I) melamine, (II) formaldehyde and (III) from about 2 to about 20.0%, by weight, based on the total weight of melamine and formaldehyde, of an ethylene glycol having a molecular weight of from about 62 to about 2,000, wherein said (1) or (2) contains, in admixture therewith, (3) from about 2.5 to about 30.0%, by weight, based on the weight of resin solids in (1) or (2), of an elastomer comprising (a) an ethylene/vinyl chloride containing from about 20 to about 30% ethylene, from about 65 to about 80% vinyl chloride and from about 0.5 to about 7.0%, by weight, said percentages being based on the total weight of (a), of amide groups, (b) a polyurethane resin containing from about 3.0 to about 10.0%, by weight, based on the total weight of (b), of carboxyl groups, or (c) a butadine/acrylonitrile copolymer containing from about 50 to about 95% butadiene, from about 5 to 50% acrylonitrile and from about 1 to about 10%, by weight, said percentages being based on the total weight of (c), of carboxyl groups, said elastomer having a particle size of up to about 20,000 Angstroms.
Claim 2
Dependent Claim
246 words
A composition of matter comprising (1) a blend of an aqueous melamine/formaldehyde resin solution and from about 2 to about 20%, by weight, based on the solids weight of said resin, of an ethylene glycol having a molecular weight of from about 62 to about 2100, or (2) an aqueous solution of the resinuous reaction product of (I) melamine, (II) formaldehyde and (III) from about 2 to about 20.0%, by weight, based on the total weight of melamine and formaldehyde, of an ethylene glycol having a molecular weight of from about 62 to about 2,000, wherein said (1) or (2) contains, in admixture therewith, (3) from about 2.5 to about 30.0%, by weight, based on the weight of resin solids in (1) or (2), of an elastomer comprising (a) an ethylene/vinyl chloride containing from about 20 to about 30% ethylene, from about 65 to about 80% vinyl chloride and from about 0.5 to about 7.0%, by weight, said percentages being based on the total weight of (a), of amide groups, (b) a polyurethane resin containing from about 3.0 to about 10.0%, by weight, based on the total weight of (b), of carboxyl groups, or (c) a butadine/acrylonitrile copolymer containing from about 50 to about 95% butadiene, from about 5 to 50% acrylonitrile and from about 1 to about 10%, by weight, said percentages being based on the total weight of (c), of carboxyl groups, said elastomer having a particle size of up to about 20,000 Angstroms.
