    Abstract: A thermally strippable double faced adhesive sheet comprising a substrate, a thermally strippable pressure-sensitive adhesive layer (A) arranged on one side of the substrate, and a pressure-sensitive adhesive layer (B) arranged on the other side of the substrate, in which the substrate comprises a porous substrate. The porous substrate preferably has a density of 0.9 g/cm3 or less and a tensile elastic modulus of 20 MPa or less. The substrate may comprise a laminate of the porous substrate and a non-porous substrate. Exemplary usable adhesives for the pressure-sensitive adhesive layer (B) include pressure-sensitive adhesives, ultraviolet-curable pressure-sensitive adhesives, thermally strippable pressure-sensitive adhesives, thermoplastic pressure-sensitive adhesives, and thermosetting pressure-sensitive adhesives.

    Abstract: In order to enable lamination of materials of different kinds, such as a synthetic resin plate and a glass plate, without leaving bubbles between the materials, a double sided adhesive sheet (1) is formed by forming an adhesive layer (3) cross-linked with ultraviolet light on one surface of a sheet (2) with an inorganic oxide layer (2B) and forming an adhesive layer (4) cross-linked by heating or moisture on the other surface of the sheet (2). A glass plate (6) is applied to the adhesive layer (3), and a synthetic resin plate (7) is applied to the adhesive layer (4), thereby forming a laminate panel (5).

    Abstract: The invention relates to a pressure-sensitive adhesive (PSA) tape, intended in particular for producing or bonding optical liquid-crystal data displays, having two PSA layers and at least one carrier sheet, characterized in that the PSA tape has light-reflecting properties on both its top and its bottom faces and at the same time is light-absorbing at least in so far as light not reflected is unable to penetrate the adhesive tape. With preference a white primer layer is provided at least between one face of the carrier sheet and the PSA layer located on that face.
