    Abstract: PROBLEM TO BE SOLVED: To provide a double-sided pressure-sensitive adhesive sheet including pressure-sensitive adhesive layers using a water-dispersible acrylic pressure-sensitive adhesive composition, and improved in anchoring performance to a plastic base material.SOLUTION: The pressure-sensitive adhesive sheet 1 is the double-sided pressure-sensitive adhesive sheet including the plastic base material 10, and the pressure-sensitive adhesive layers 14, 15 provided respectively on respective faces thereof. The pressure-sensitive adhesive layers 14, 15 are formed of the water-dispersible pressure-sensitive adhesive composition dispersed with an acrylic polymer in an aqueous solvent. An anchor layer 12 formed of an anchoring composition containing a polyester-polyurethane dissolved in an organic solvent is provided between at least one face 10A of the base material 10, and the pressure-sensitive adhesive layer 14.

    Abstract: PROBLEM TO BE SOLVED: To provide an adhesive tape for protecting a surface of a semiconductor wafer, which allows a thin film wafer having a thickness of ≤100 μm to be formed even when a rear surface of the semiconductor wafer is ground with the adhesive tape stuck to the semiconductor wafer.
    SOLUTION: The adhesive tape for protecting the surface of a semiconductor wafer has: a substrate resin film; and a direct adhesive layer on the substrate resin film through an intermediate resin layer in which base resin components containing an acrylic copolymer and/or polyurethane acrylate copolymer are cross-linked. The repulsion coefficient γ obtained by dividing repulsion force α per unit width, which is found from the load of loop stiffness obtained by measuring the adhesive tape for protecting the surface of the semiconductor wafer under a specific condition, by the square of the thickness β of a substrate is 100 mN/mm
    3 or more, the repulsion force α is 13 mN/mm or less, and the difference between tensile fracture elongations in a longitudinal direction and a lateral direction is 35% or less.
