<P>PROBLEM TO BE SOLVED: To provide a repeelable adhesive sheet excellent in appearance characteristics, and excellent in prevention property to rise of the adhesive force over time, the low fouling property, the scratch resistance and the antistatic properties as well. <P>SOLUTION: The adhesive sheet has an acrylic adhesive agent layer at least on one surface of a transparent film substrate, wherein the transparent film substrate has a base layer including a resin material, and a topcoat layer constituted of a polythiophene, an acrylic resin and a melamine-based crosslinking agent on a first surface of the base layer, and has an average thickness D<SB POS="POST">ave</SB>of 2 to 50 nm and a variation in thickness ΔD of ≤40%; and the adhesive layer is formed of a repeelable water-dispersion type acrylic adhesive agent composition constituted of an alkyl (meth)acrylate ester and a carboxyl group-containing unsaturated monomer as essential raw material monomers, wherein the contents of the alkyl (meth)acrylate ester and the carboxyl group-containing unsaturated monomer in the whole raw material monomers are 70 to 99.5 wt.% and 0.5 to 10 wt.%, respectively, and containing an acrylic emulsion-based polymer (A) polymerized using a reactive emulsifier containing a radically polymerizable functional group in its molecule, a compound (B) represented by formula (I): R<SP POS="POST">a</SP>O-(PO)<SB POS="POST">l</SB>-(EO)<SB POS="POST">m</SB>-(PO)<SB POS="POST">n</SB>-R<SP POS="POST">b</SP>, and an acetylenediol-based compound (C) having an HLB value of <13. <P>COPYRIGHT: (C)2013,JPO&INPIT |
