Paint coat-protecting removable pressure-sensitive adhesive sheet

A method of using a pressure-sensitive adhesive sheet as a removal adhesive sheet for protecting an incompletely-cured coat, which comprises:

• providing the pressure-sensitive adhesive sheet comprising a base sheet and a pressure-sensitive adhesive layer on the base sheet, the pressure-sensitive adhesive layer being formed of an emulsion pressure-sensitive adhesive composition that includes an emulsion of an ethylene-vinyl carboxylate copolymer as a main component, wherein the emulsion of the ethylene-vinyl carboxylate copolymer is an emulsion of (A) a copolymer obtained by subjecting a monomer mixture that includes ethylene and a vinyl carboxylate to emulsion copolymerization, or is an emulsion of (B) a copolymer obtained by polymerizing an alkyl(meth)acrylate using the emulsion of the copolymer (A) as a seed emulsion and the ratio of repeating unit origination from copolymer (A) to a repeating unit originating from alkyl(meth)acrylate in copolymer (B) is 70:30 to 90:10 (mass %), and
• attaching the pressure sensitive adhesive sheet to an incompletely cured coat, and then
• removing the pressure sensitive adhesive sheet from the coat without swelling or whitening of the coat or adhesive transfer.
