<P>PROBLEM TO BE SOLVED: To provide a double-sided adhesive sheet which does not corrode a metal surface even when applied directly onto a metal surface, and of which the adhesive layer is excellent in cohesive strength, which is hard to cause the delamination under a high temperature environment and the reduction in the visibility owing to the discoloration, and which is excellent in the peeling resistance. <P>SOLUTION: This double-sided adhesive sheet uses a pressure-sensitive adhesive layer comprising the acrylic-based adhesive composition which contains the (meth)acrylic ester copolymer (A) containing a (meth)acrylic ester monomer as a principal monomer component and not containing a carboxylic group-containing monomer and the (meth)acrylic ester copolymer (B) containing a (meth)acrylic ester monomer and a nitrogen atom-containing copolymerizable monomer as the monomer components and not containing a carboxylic group-containing monomer, consequently attains that it permits the suitable insurance of the cohesive strength of the adhesive even not containing an acid component, has the little corrosiveness to a metal surface, and is hard to cause the delamination under high temperatures and the reduction in the visibility owing to the discoloration. <P>COPYRIGHT: (C)2011,JPO&INPIT |
