Claims
- 1. A coating composition suitable for coating polyvinyl chloride articles of manufacture, said composition being curable on a substrate and said composition comprising:
- a) a vehicle comprising polymers selected from the group consisting of polyether, polycaprolactone, vinyl chloride polymers and mixtures thereof, said polymers contain hydroxyl groups, carboxyl groups, or both said groups,
- b) an isocyanate crosslinking agent,
- c) a solvent for said vehicle and crosslinking agent, and
- d) finely divided thermoplastic resin particles ranging in size from 0.05 to 200 .mu.m in suspension,
- wherein said vehicle is branched to the extent that a paint film which is obtained by crosslinking said composition to form a polymer lattice of large mesh that is adherent to said polyvinyl chloride article of manufacture allows the plasticizers used in making said polyvinyl chloride article of manufacture to exude through said mesh.
- 2. A coating composition suitable for coating polyvinyl chloride articles of manufacture, said composition being curable on a substrate and said composition comprising:
- a) a vehicle comprising a mixture of two resins A1 and A2, wherein A1 is a resin containing hydroxyl and/or carboxylic groups and is selected from the group consisting of polyacrylate, epoxy resin, polyether, polyester, polycaproclactone and mixtures thereof, and A2 is a chlorinated vinyl resin containing hydroxyl and/or carboxylic groups,
- b) an isocyanate crosslinking agent.
- c) a solvent for said vehicle and crosslinking agent, and
- d) finely divided thermoplastic resin particles ranging in size from 0.05 to 200 .mu.m in suspension,
- wherein said vehicle is branched to the extent that a paint film which is obtained by crosslinking said composition to form a polymer lattice of large mesh that is adherent to said polyvinyl chloride article of manufacture allows the plasticizers used in making said polyvinyl chloride article of manufacture to exude through said mesh.
- 3. The composition according to claim 2, wherein the resin A1 is a hydroxylated polyester resin and the resin A2 is a hydroxylated vinyl acetochloride copolymer.
- 4. The coating composition of claim 2 wherein said finely divided thermoplastic resin particles range in size from about 20 .mu.m to about 60 .mu.m.
- 5. An article of manufacture comprising polyvinyl chloride sections or joinery and its accessories made of polyvinyl chloride, wherein said sections, joinery, and joinery accessories are coated with a composition according to claim 2.
- 6. A method of making an article of manufacture comprising coated polyvinyl chloride sections or joinery and its accessories made of polyvinyl chloride which comprises coating said sections, joinery, or joinery accessories with a composition according to claim 2.
- 7. The composition according to one of claims 1 to 3, wherein said crosslinking agent is a non-blocked polyisocyanate compound.
- 8. The composition according to one of claims 1 to 3, wherein said finely divided thermoplastic resin is a polyamide powder.
- 9. The composition according to one of claims 1 to 3, wherein said composition also contains pigments, dyes, and fillers.
