Abstract: Provided is a PSA sheet that provides highly reliable adhesion and great stretch removability from adherends. This invention provides a PSA sheet. The PSA sheet exhibits a shear adhesive strength of 0.5 MPa or greater, a tensile strength at break of 10 MPa or greater, and an elongation at break of 300% or greater.

Abstract: This invention provides a PSA sheet that allows prevention or reduction of damage such as fracture with efficient stretch removability. A stretchable PSA sheet is provided, comprising a PSA layer and a film-like substrate supporting the PSA layer. The PSA sheet has a long section. The long section has a tapered segment that extends, tapering to a first end of the length direction and the film-like substrate has a minimum cross-sectional area larger than 0.30 mm2 in the tapered segment.

Abstract: A pressure-sensitive adhesive tape includes a substrate layer, a colored layer, and a pressure-sensitive adhesive layer. The substrate layer is formed of a plastic material, such as polyethylene terephthalate. The colored layer is laminated on one major surface of the substrate layer. The colored layer is a black printed layer formed by printing, for example, black ink. The pressure-sensitive adhesive layer is laminated on the other major surface of the substrate layer. An acrylic polymer is preferably used as the pressure-sensitive adhesive layer. In the pressure-sensitive adhesive tape, a specular reflectance of visible light on the surface near to the colored layer is 2.0% or smaller.

Abstract: A pressure-sensitive adhesive tape according to an embodiment includes a substrate layer, a first pressure-sensitive adhesive layer and a second pressure-sensitive adhesive layer provided on both sides of the substrate layer, respectively. The total thickness of the substrate layer, the first pressure-sensitive adhesive layer, and the second pressure-sensitive adhesive layer is 10 ?m or less. The average thickness of each of the first and second pressure-sensitive adhesive layers of which the pressure-sensitive adhesive tape is composed is 3.5 ?m or less. The standard deviation of the thickness of the pressure-sensitive adhesive layer is 25% or less based on the average thickness of the pressure-sensitive adhesive layer.

Abstract: A pressure-sensitive adhesive tape includes a substrate layer made of a plastic material, etc., and a pressure-sensitive adhesive layer provided on at least one of the surfaces of the substrate layer. The pressure sensitive adhesive tape has the thermal resistance at 80° C. of less than 2.00 [cm2*K/W] and the total thickness of the substrate layer and the pressure-sensitive adhesive layer of less than 10 ?m. In addition, the pressure-sensitive adhesive layer may be provided on both surfaces of the substrate layer. The total thickness of the substrate layer and the pressure-sensitive adhesive layer may be less than 6 ?m.
