<P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive tape which has sufficient tackiness and high adhesive power with less adhesive deposit. <P>SOLUTION: The pressure-sensitive adhesive tape comprises a substrate and an adhesive layer formed at least on one surface of the substrate. The adhesive layer includes a coating of a pressure-sensitive adhesive composition which contains, in specific ratios, (A) a (meth)acrylic copolymer; (B) a tackifying resin; and (C) an imine- or isocyanate-based compound, the (meth)acrylic copolymer being obtained by polymerizing a monomer mixture containing, in specific ratios, (a) a (meth)acrylic alkyl ester having 5-12C alkyl, (b) a carboxy-containing monomer, (c) a specific ester compound having 1-4C alkyl and vinyl or isopropenyl, and, as occasion demands, (d) another polymerizable monomer. The mixing ratio of the component (c) in the monomer mixture is less than 0.15 pt.mass relative to 1 pt.mass of the component (a). <P>COPYRIGHT: (C)2013,JPO&INPIT |
