<P>PROBLEM TO BE SOLVED: To provide a transparent self-adhesive sheet, causing no sticking of the cut edge face with time when a laminated form made by laminating it via a self-adhesive sheet is cut, and also stickable with no air cells left even there are unevennesses on an adherend surface, further, stickable without foaming even if an adherend is made of an out-gas-emitting material such as a plastic material. <P>SOLUTION: The transparent self-adhesive sheet is such as to have one or more first self-adhesive layers and second self-adhesive layers differing in viscoelastic behavior from each other, and have a structure made by laminating integratedly these layers. This transparent self-adhesive sheet has dynamic shearing storage moduli G', determined by a temperature dispersion of 1 Hz frequency, of 2×10<SP POS="POST">4</SP>to 5×10<SP POS="POST">5</SP>Pa at 20°C and 1×10<SP POS="POST">4</SP>to 1×10<SP POS="POST">5</SP>Pa at 150°C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
