Claims
- 1. An aqueous paint suspension comprising:
- (a) from about 20 to about 30 percent by weight water;
- (b) from about 5 to about 15 percent by weight of a polyvinylpyrrolidone/vinyl acetate copolymer, the polyvinylpyrrolidone/vinyl acetate copolymer containing from about 30 to about 70 percent by weight polyvinylpyrrolidone and from about 30 to about 70 percent by weight vinyl acetate;
- (c) from about 20 to about 40 percent by weight of a dispersed substance selected from the group consisting of filler and pigment, and mixtures thereof;
- (d) from about 0.05 to about 3 percent by weight of a fumed silica suspending agent;
- (e) from about 0.1 to about 3 percent by weight of a non-silicone defoaming agent; and
- (f) from about 0.5 to about 5 percent by weight of a dispersing agent, the dispersing agent comprising a block copolymer having an affinity for pigment;
- wherein the dispersed substance is not encapsulated within the polyvinylpyrrolidone/vinyl acetate coploymer.
- 2. The aqueous paint suspension of claim 1, wherein the polyvinylpyrrolidone/vinyl acetate copolymer contains about 30 percent by weight polyvinylpyrrolidone and about 70 percent by weight vinyl acetate.
- 3. The aqueous paint suspension of claim 1, further comprising from about 0.5 to about 3 percent by weight of a wetting agent, the wetting agent comprising a carboxylic acid ester having an affinity for pigment.
- 4. The aqueous paint suspension of claim 3, further comprising from about 7 to about 12 percent by weight acetone.
- 5. The aqueous paint suspension of claim 4, further comprising from about 15 to about 20 percent by weight of a C.sub.1 -C.sub.6 aliphatic alcohol.
- 6. An aqueous aerosol paint comprising:
- (a) from about 65 to about 95 percent by weight of an aqueous paint suspension comprising:
- (i) from about 20 to about 30 percent by weight water;
- (ii) from about 5 to about 15 percent by weight of a polyvinylpyrrolidone/vinyl acetate copolymer, the polyvinylpyrrolidone/vinyl acetate copolymer containing from about 30 to about 70 percent by weight polyvinylpyrrolidone and from about 30 to about 70 percent by weight vinyl acetate;
- (iii) from about 20 to about 40 percent by weight of a dispersed substance selected from the group consisting of filler and pigment, and mixtures thereof;
- (iv) from about 0.05 to about 3 percent by weight of a fumed silica suspending agent;
- (v) from about 0.1 to about 3 percent by weight of a non-silicone defoaming agent; and
- (vi) from about 0.5 to about 5 percent by weight of a dispersing agent, the dispersing agent comprising a block copolymer having an affinity for pigment;
- wherein the dispersed substance is not encapsulated within the polyvinylpyrrolidone/vinyl acetate coploymer; and
- (b) from about 5 to about 35 percent by weight of a C.sub.2 -C.sub.7 hydrocarbon propellant.
- 7. The aqueous aerosol paint of claim 6, wherein the C.sub.2 -C.sub.7 hydrocarbon propellant is selected from the group consisting of ethane, propane, n-butane, and isobutane, and mixtures thereof.
- 8. The aqueous aerosol paint of claim 7, wherein the C.sub.2 -C.sub.7 hydrocarbon propellant is a mixture of propane and isobutane.
