Abstract

The present invention is a paint coat-protecting removable pressure-sensitive adhesive sheet comprising a base sheet, and a pressure-sensitive adhesive layer that is provided 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. The present invention provides a paint coat-protecting removable pressure-sensitive adhesive sheet that does not cause swelling, whitening, and adhesive transfer even when the pressure-sensitive adhesive sheet is attached to the surface of a paint coat that has not been sufficiently dried (i.e., contains a small amount of solvent) or has not been sufficiently cured after drying, and removed from the paint coat.
