  • Publication number: 20020009587
    Abstract: 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.

  • Publication number: 20010020515
    Abstract: 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 has, on a side opposite the substrate side, a modified surface layer having a thickness of 100 nm or smaller and having a higher functional group concentration than the inner parts of the adhesive layer; and a process for producing the sheet which comprises subjecting a rubber-based pressure-sensitive adhesive layer formed on a substrate to a treatment for generating functional groups on the surface of the adhesive layer. The sheet, even when applied to a poorly bondable paint film apt to cause adhesion failures due to bleeding, etc.
