Claims
- 1. A paint peeling method comprising the steps of:
- applying to an object not to be painted a paint peeling composition containing as effective components thereof 20 to 96% by weight of a coating-formable water-insoluble high polymer compound and 2 to 25% by weight of a substance capable of forming a group of minute bubbles in an applied coating per se;
- curing said paint peeling composition to form a coating on the object and causing said substance to expand in volume; and
- peeling the coating off the object after excess paint has been accumulated thereon together with the accumulated excess paint, the expansion in volume of said substance facilitating the peeling of the coating off the object.
- 2. A paint peeling method as defined in claim 1, wherein said water-insoluble high polymer compound comprises at least one selected from the group consisting of ureamelamine resin, chloroprene latex, ethylene vinyl-acetate copolymer latex and polystyrene.
- 3. A paint peeling method as defined in claim 1, wherein said substance comprises a foamed hollow matter.
- 4. A paint peeling method as defined in claim 3, wherein said foamed hollow matter comprises at least one selected from the group consisting of shirasu balloons, glass balloons, carbon balloons and foamed synthetic resin balloons.
- 5. A paint peeling method as defined in claim 1, wherein said substance comprises an unfoamed hollow matter capable of foaming upon baking after being applied to the object not to be painted.
- 6. A paint peeling method as defined in claim 5, wherein said unfoamed hollow matter comprises a synthetic resin balloon.
- 7. A paint peeling method as defined in claim 1, wherein said substance comprises a matter capable of self-decomposing to generate gas when baked after being applied to the object not to be painted.
- 8. A paint peeling method as defined in claim 7, wherein said matter capable of self-decomposing contains a an effective component thereof azobisisobutyronitrile.
- 9. A paint peeling method as defined in claim 1, wherein said substance comprises a chemical matter capable of generating gas by a chemical reaction after being applied to the object not to be painted.
- 10. A paint peeling method as defined in claim 1, wherein said substance comprises a low boiling solvent to be foamed by baking after being applied to the object not to be painted.
- 11. A paint peeling method as defined in claim 1, wherein said substance comprises highly-pressured fluorocarbon gas to be foamed when the pressure is reduced to atmospheric pressure after being applied to the object not to be painted.
- 12. A paint peeling method as defined in claim 1, wherein said paint peeling composition has a ratio of high polymer compound to bubble-formable substance ranging in % by weight from 24:1 to 3:1.
