Document Type and Number:
WIPO Patent Application WO/2010/064623
Kind Code:
A1
Abstract:
Provided is a pressure-sensitive adhesive sheet that has a pressure-sensitive adhesive layer with both high corrosion resistance and adhesive reliability. The acrylic pressure-sensitive adhesive sheet has at least an acrylic pressure-sensitive adhesive layer having as the main component an acrylic polymer formed with a composition that contains a monomer mixture, or a partial polymer thereof, comprising (m1), (m2) and (m3), or (m1), (m2), (m3) and (m4), wherein the content of the individual components is 35-97.5 mass% (m1), 2-40 mass% (m2), 0.1-25 mass% (m3) and 0-30 mass% (m4). (m1) is an alkyl (meth)acrylate monomer having a C1-12 alkyl group and represented by formula (1): CH2 = C (R1)COOR2 (formula (1)) (In formula (1), R1 represents a hydrogen atom or a methyl group, and R2 represents a C1-12 alkyl group.), (m2) is a vinyl monomer having a nitrogen atom in the skeleton (excluding (m3)), (m3) is an N-hydroxyalkyl (meth)acrylamide monomer having a C1-4 hydroxyalkyl group, and (m4) is a monomer that is copolymerizable with the (m1)-(m3).
