Abstract: An objective is to provide a surface protective PSA sheet that has well-balanced bonding strength for various adherends differing in polarity and a capability to suppress peeling and lifting as well as an ability to inhibit touch-up paint peeling and an increase in bonding strength with time. The surface protective PSA sheet having a PSA layer and a resin substrate supporting the PSA layer, characterized by satisfying the following conditions (a1), (a1-1) and (c1) has well-balanced bonding strength for various adherends differing in polarity and is capable of suppressing peeling and lifting and inhibiting touch-up paint peeling and an increase in boding strength with time. (a1) The PSA layer is formed from a PSA composition comprising a (meth)acrylic copolymer and a tackifier, the tackifier accounting for 1.0-30 parts by mass of the PSA composition with the (meth)acrylic copolymer being 100 parts by mass. (a1-1) The (meth)acrylic copolymer comprises 0.1-2.

Abstract: A pressure-sensitive adhesive tape includes a pressure-sensitive adhesive layer containing a pressure-sensitive adhesive composition, a bubble, and a hollow inorganic fine particle. When a pinhole region is present in the pressure-sensitive adhesive layer where the light that has been radiated onto one surface of the pressure-sensitive adhesive layer is transmitted through the pressure-sensitive adhesive layer up to the other surface thereof, and when the pressure-sensitive adhesive tape is bisected with a line intersecting the longitudinal direction of the tape at right angles, 60% or more of large pinhole regions each having a diameter of 1.5 mm or more are present in either of the two portions. Thereby, when the pressure-sensitive adhesive tape is to be wound, the tape can be easily wound or it can be suppressed that the pressure-sensitive adhesive composition may be forced out.

Abstract: A pressure-sensitive adhesive tape includes a pressure-sensitive adhesive layer as a pressure-sensitive adhesive containing a pressure-sensitive adhesive composition, a bubble, and a hollow inorganic fine particle. The hollow inorganic fine particle contains at least sodium and silicon, and the mass ratio of the sodium and the silicon that are contained in the hollow inorganic fine particle (Na/Si) is 0.5 or less. Thereby, the size of the pinhole and the number of the pinholes in the pressure-sensitive adhesive tape can be suppressed, the pinhole having a structure in which, when light is radiated onto one surface of the pressure-sensitive adhesive layer that is in the state of not being laminated on a substrate, the transmission amount of the light on the other surface thereof exceeds a predetermined threshold value, as a result of the presence of a bubble having a predetermined size or more in the pressure-sensitive adhesive layer.
