摘要
(WO200183878) A coated substrate comprises a strippable intermediate coating atop the substrate and a strip agent-permeable waterborne overcoat adhered to the intermediate coating, wherein the dried overcoat is less trippable and more wear-resistant than the dried intermediate coating.  When the overcoat eventually becomes worn and must be renewed, a strip agent (e.g., chemical strip agent) can be applied to the overcoat.  The strip agent penetrates the overcoat and attacks the intermediate coating, thereby enabling removal of the intermediate coating and overcoat without aggressive removal techniques such as sanding.

主权利要求
(WO200183878) We claim: 1. A coated substrate comprising a strippable intermediate coating atop the substrate and an overcoat atop the intermediate coating, characterized in that the overcoat was waterborne and when dried is strip agent-permeable, adhered to the intermediate coating, and less strippable and more wear-resistant than the dried intermediate coating. 2. A coated substrate according to claim 1, further characterized in that the substrate comprises a floor. 3. A coated substrate according to claim 2, further characterized in that the substrate comprises a resilient flooring material. 4. A coated substrate according to any preceding claim, further characterized in that the intermediate coating comprises an acrylic. 5. A coated substrate according to any preceding claim, further characterized in that the intermediate coating has a strippability rating of 6 or more on a 7 point scale, coπesponding to at least partial strip with softened coating in all areas, using a test strip agent made using a 25%> water solution of a concentrate that contained 59% softened water, 6% sodium xylene sulfonate, 4.5% potassium hydroxide, 10%> monoethanolamine, 0.2%> tetrasodium EDTA, 10% ethylene glycol phenyl ether and 0.05% fluorosurfactant, and a 30 minute standing time. 6. A coated substrate according to any preceding claim, further characterized in that the overcoat comprises an emulsion, suspension or dispersion. 7. A coated substrate according to any preceding claim, further characterized in that the overcoat is radiation curable. 8. A coated substrate accordmg to any preceding claim, further characterized in that the overcoat is UN-curable. 9. A coated substrate according to any preceding claim, further characterized in that the dried overcoat has a strippability rating of 4 or less on a 7 point scale, coπesponding to no more than severe chemical attack on the overcoat and the onset of stripping, using a test strip agent made using a 25%ι water solution of a concentrate that contained 59% softened water, 6% sodium xylene sulfonate, 4.5% potassium hydroxide, 10% monoethanolamine, 0.2%> tetrasodium EDTA, 10% ethylene glycol phenyl ether and 0.05%> fluorosurfactant, and a 30 minute standing time. 10. A strippable laminate finish kit comprising coatings in two or more containers, characterized in that one of the containers comprises a strippable intermediate coating and another of the containers comprises a waterborne overcoat, wherein the dried overcoat is strip agent-permeable, adheres to the intermediate coating, and is less strippable and more wear resistant than the dried intermediate coating. 11. A strippable laminate finish kit according to claim 10, further characterized in that the overcoat comprises a UN curable material. 12. A strippable laminate finish kit according to any of claims 10 to 11, further characterized in that the overcoat comprises an acrylate, urethane or acrylated urethane. 13. A strippable laminate finish kit according to any of claims 10 to 12, further characterized in that the overcoat comprises an aromatic urethane. 14. A method for applying a finish to a substrate to form a coated substrate according to claim 1, comprising: a) applying to the substrate a strippable intermediate coating; b) drying the inteπnediate coating; and c) applying an overcoat; characterized in that the overcoat is waterborne and when dried is strip agent-permeable, adheres to the intermediate coating, and is less strippable and more wear resistant than the dried intermediate coating. 15. A method according to claim 14, further characterized in that the overcoat comprises an emulsion, suspension or dispersion. 16. A method according to any of claims 14 to 15, further characterized in that the overcoat comprises an acrylate, urethane or acrylated urethane. 17. A method according to any of claims 14 to 16, further characterized in that the overcoat is UV curable. 18. A method for removing the coatings from a substrate according to claim 1, comprising: a) applying a strip agent to a dried radiation cured overcoat atop a dried intermediate layer atop the substrate; b) allowing the strip agent to permeate through the overcoat to attack the intermediate layer; and c) removing the intermediate layer and overcoat without removing substantial portions of the underlying substrate; characterized in that the overcoat was waterborne and adhered to the intermediate layer. 19. A method according to claim 18, further characterized in that permeation of the strip agent through the overcoat is enhanced by a mechanically roughening the overcoat prior to applying the strip agent. 20. A method according to any of claims 18 to 19, further characterized in that removal of the intermediate layer and overcoat occurs in less than 10 minutes after application of the strip agent.
