Patent ID: 8153262

Claim:
A strippable floor coating comprising: a primer layer (D) formed over a floor surface; an undercoat layer (A) to be applied to the primer layer (D); and a strippable overcoat layer (B) over the undercoat layer (A), wherein the undercoat layer (A) is formed from an undercoating agent having film-formability, said undercoating agent comprising: an emulsified dispersion (a1) mainly comprising at least one substance selected from the group consisting of oxidized polyolefins, natural waxes, C 10 -C 34 fatty acids, C 14 -C 34 alcohols, and esters between C 10 -C 34 fatty acids and C 14 -C 34 alcohols, or a composition (a2) comprising (i) a paraffin and/or a polyethylene each having an acid number of 0 and (ii) a resin emulsion, wherein the overcoat layer (B) is formed from a floor polish composition mainly containing (1) a urethane resin emulsion comprising silylated urethane resins, (2) a leveling agent, (3) a filming aid, and (4) a crosslinking agent, and silylated urethane resins, and wherein the undercoat layer (A) has greater adhesion to the primer layer (D) than to the overcoat layer (B) so that the overcoat layer (B) alone is stripped off by hand in the form of a sheet at the interface with the undercoat layer (A).
