PRESSURE SENSITIVE ADHESIVE SHEET |
摘要 |
<p>The present invention relates to a pressure sensitive adhesive sheet including a pressure sensitive adhesive layer on at least one surface of a base material, wherein the pressure sensitive adhesive layer is made of a two-layer structure of a first pressure sensitive adhesive layer and a second pressure sensitive adhesive layer in this order from the side of the base material; a first pressure sensitive adhesive constituting the first pressure sensitive adhesive layer has a loss tangent (tan delta) value at 0° C. of 0.25 or more and a storage elastic modulus value at 0° C. of from 0.01 to 0.80 MPa; and a resin component contained in a second pressure sensitive adhesive constituting the second pressure sensitive adhesive layer contains from 10 to 100 t by mass of an acrylic copolymer having a crosslinkable functional group. The pressure sensitive adhesive sheet according to the present invention exhibits an excellent adhesive strength even when the pressure sensitive adhesive layer is reduced in thickness.</p> |
