摘要： 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.

摘要： The present invention provides an automotive wheel protection pressure-sensitive adhesive film comprising a base layer and a pressure-sensitive adhesive layer, the pressure-sensitive adhesive layer being formed of an acrylic-based pressure-sensitive adhesive that includes at least a (meth)acrylic-based polymer, a crosslinking agent, and a UV absorber, the (meth)acrylic-based polymer including a repeating unit derived from a monomer that includes a crosslinkable functional group, and a repeating unit derived from a C1-14 alkyl ester of (meth)acrylic acid. This automotive wheel protection pressure-sensitive adhesive film exhibits sufficient adhesion when transporting or displaying an automobile, and can be easily removed even after being exposed to an outdoor environment, and rarely allows an adhesive residue to remain.
