Abstract: 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.
