发明名称 ADHESIVE SHEET
摘要 <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 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 &Delta;D of &le;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, and a compound (B) represented by formula (I): R<SP POS="POST">1</SP>O-(PO)<SB POS="POST">a</SB>-(EO)<SB POS="POST">b</SB>-(PO)<SB POS="POST">c</SB>-R<SP POS="POST">2</SP>, wherein R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>are a linear or branched alkyl group, or a hydrogen atom; PO is an oxypropylene group; EO is an oxyethylene group; and a, b and c are each a positive integer. <P>COPYRIGHT: (C)2013,JPO&INPIT
