<p><P>PROBLEM TO BE SOLVED: To provide a pressure sensitive adhesive sheet having a pressure sensitive adhesive layer provided with a combination of high corrosion resistance and reliability of adhesiveness. <P>SOLUTION: The acrylic pressure sensitive adhesive sheet includes at least an acrylic pressure sensitive adhesive layer comprising an acrylic polymer as a main component formed by a composition containing a monomer mixture or a partially polymerized substance thereof, the monomer mixture comprising (m1), (m2), and (m3), or (m1), (m2), (m3), and (m4), wherein the contents of constituents (m1), (m2), (m3), and (m4) are respectively 35-97.5 wt.%, 2-40 wt.%, 0.1-25 wt.%, and 0-30 wt.%, and (m1), (m2), (m3), and (m4) are respectively an alkyl methacrylate monomer having a 1-12C alkyl represented by formula (1): CH<SB>2</SB>=C(R<SP>1</SP>)COOR<SP>2</SP>where R<SP>1</SP>is a hydrogen atom, or a methyl, and R<SP>2</SP>is a 1-12C alkyl; a vinyl monomer having a nitrogen atom in its skeleton (except for (m3)); a N-hydroxylalkyl methacrylamide monomer having 1-4C hydroxyalkyl; and a monomer copolymerizable with the (m1)-(m3). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
