A sheet for protecting a paint film, the sheet comprising a substrate and formed on one side thereof a rubber-based pressure-sensitive adhesive layer which comprises a rubbery polymer and incorporated therein a copolymer of at least one aromatic compound with at least one terpene compound or aliphatic hydrocarbon compound. The sheet can be efficiently applied and satisfactorily adhered to a paint film and retain the satisfactorily adherent state over long. After accomplishment of the protection, the sheet can be easily peeled off and is less apt to foul the paint film even when the paint film is of the type susceptible to fouling upon protective sheet removal. No cleaning treatment is hence necessary.
