Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 291 words
An aerosol composition having a pH of about 7.2 to about 10 and suitable for spray application to a substrate surface and air drying to a continuous film thereon which has high gloss and excellent durability including high flexibility retention and high gloss retention, said composition consists essentially of: (a) about 10 to about 30% by weight of at least one propellant, (b) about 15 to about 35% by weight of at least one aliphatic monohydric alcohol of the formula: R-OH wherein R is an unsubstituted straight or branched chain alkyl group, and containing 1 to 4 carbon atoms, (c) about 10 to about 45% by weight of water, (d) about 8 to about 25% by weight of an insoluble film forming acrylic polymer in particulate form suspended in said composition, said acrylic polymer consisting of a water-insoluble interpolymer of (A) units from at least one neutral free-radical polymerizable ester having a vinylidene group attached to the functional group, which ester by itself yields a soft linear polymer, (B) units from at least one polymerizable aromatic monovinylidene compound which by itself yields a hard polymer, and (C) units from at least one neutral polymerizable aliphatic monovinylidene compound substituted by a cyano group and which by itself yields a hard polymer, (e) up to about 3% by weight of at least one surfactant present in an amount at least sufficient to maintain solids suspended in the liquid phase, (f) 0 to about 15% by weight of a pigment, (g) 0 to about 5% by weight of a coalescing solvent, (h) 0 to about 1% by weight of a pH stabilizer, (i) 0 to about 2% by weight of an antifoam agent, and (j) 0 to about 2% by weight of a plasticizer.
Claim 2
Dependent Claim 291 words
An aerosol composition having a pH of about 7.2 to about 10 and suitable for spray application to a substrate surface and air drying to a continuous film thereon which has high gloss and excellent durability including high flexibility retention and high gloss retention, said composition consists essentially of: (a) about 10 to about 30% by weight of at least one propellant, (b) about 15 to about 35% by weight of at least one aliphatic monohydric alcohol of the formula: R-OH wherein R is an unsubstituted straight or branched chain alkyl group, and containing 1 to 4 carbon atoms, (c) about 10 to about 45% by weight of water, (d) about 8 to about 25% by weight of an insoluble film forming acrylic polymer in particulate form suspended in said composition, said acrylic polymer consisting of a water-insoluble interpolymer of (A) units from at least one neutral free-radical polymerizable ester having a vinylidene group attached to the functional group, which ester by itself yields a soft linear polymer, (B) units from at least one polymerizable aromatic monovinylidene compound which by itself yields a hard polymer, and (C) units from at least one neutral polymerizable aliphatic monovinylidene compound substituted by a cyano group and which by itself yields a hard polymer, (e) up to about 3% by weight of at least one surfactant present in an amount at least sufficient to maintain solids suspended in the liquid phase, (f) 0 to about 15% by weight of a pigment, (g) 0 to about 5% by weight of a coalescing solvent, (h) 0 to about 1% by weight of a pH stabilizer, (i) 0 to about 2% by weight of an antifoam agent, and (j) 0 to about 2% by weight of a plasticizer.
Claim 3
Dependent Claim 27 words
The composition of claim 1 wherein said film-forming polymer is a copolymer of styrene, acrylonitrile and an acrylate ester having a molecular weight of about 1 million,
Claim 4
Dependent Claim 18 words
The composition of claim 1 wherein said polymer is present in an amount of about 15% by weight.
Claim 5
Dependent Claim 22 words
The composition of claim 1 wherein said pigment is present in an amount of from about 5 to about 15% by weight.
Claim 6
Dependent Claim 31 words
The composition of claim 4 wherein said antifoam agent is present in an amount of about 1% by weight, said plasticizer is present in an amount of about 1% by weight.
