摘要： Provided is a PSA sheet that allows installation of a protection sheet with good shape precision on the surface of an object to be protected. The PSA sheet provided by this invention comprises a substrate whose primary component is a resin film and a PSA layer placed on one face of the substrate. The PSA sheet comprises a protection sheet part which is adhered to an adherend to protect it, a marginal part bounded from the protection sheet part by a tear-off line surrounding the protection sheet part, and a tear-aiding structure provided along the tear-off line. The PSA sheet is configured so that after the protection sheet part is adhered to the adherend, when the marginal part is pulled in a direction in which the PSA sheet is peeled off the adherend, the marginal part is torn off the protection sheet part.

摘要： 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 0.1-2.8% by mass functional group-containing structural unit, the structural unit including at least one species of functional groups selected from the group consisting of a carboxyl group and a salt thereof as well as a sulfo group and a salt thereof. (c1) The surface protective PSA sheet has tensile moduli of elasticity of 180-330 MPa in both MD and TD.
