  • Patent number: 6586090
    Abstract: The present invention provides an adhesive tape comprising a substrate and an adhesive layer formed on at least one side of the substrate, wherein the substrate comprises the following Component A, Component B and Component C: Component A: a thermoplastic resin having a carbonyl oxygen atom in the molecular skeleton Component B: a polymer alloy containing an ethylene component and a propylene component Component C: an inorganic metal compound surface-treated with a silane coupling agent but substantially no halogen atom. The adhesive tape and the substrate for the adhesive tape of the present invention are free of generation of dioxin or a toxic gas upon incineration, are superior in flexibility, resistance to thermal deformation, flame resistance and resistance to surface whitening, and show suitable stretchability and mechanical strength.

  • 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.
