<P>PROBLEM TO BE SOLVED: To provide a self-adhesive sheet which is a laminate including a laminate structure of a substrate layer (A)/a self-adhesive layer (B), with superior adhesiveness between the substrate layer (A) and the self-adhesive layer (B). <P>SOLUTION: The self-adhesive sheet is a self-adhesive sheet which is a laminate including a laminate structure of a substrate layer (A)/a self-adhesive layer (B). The laminate is collectively formed through coextrusion molding. Under the condition in which the measurement temperature is 23°C, the tensile speed is 0.3 m/minute, and the peeling angle is 180 degrees, the peeling force when peeling the self-adhesive layer (B) from the substrate layer (A) is 2.5 N/20 mm or more. <P>COPYRIGHT: (C)2012,JPO&INPIT |
