Document Type and Number:
Japanese Patent JP6644129
Kind Code:
B2
Abstract:
To provide an adhesive layer having the performances of high adhesion and high stickiness although it is thin with a thickness of 1 μm-20 μm, and an adhesive film prepared therewith.SOLUTION: An adhesive layer has a copolymer with a weight average molecular weight of 200,000-2,000,000, obtained by copolymerizing of (A-1) the total 100 pts.wt. of at least one alkyl (meth) acrylate monomer with a C1-C14 alkyl group or (A-2) the total 100 pts.wt. of at least one alkyl (meth) acrylate monomer with a C1-C14 alkyl group and at least one aromatic group-containing (meth) acrylate monomer, with (B) at least one nitrogen-containing vinyl monomer of 5-50 pts.wt., and (C) at least one carboxyl group-containing copolymerizable vinyl monomer of 0.1-2 pts.wt., and/or at least one a hydroxyl group-containing copolymerizable vinyl monomer of 0.1-5 pts.wt.SELECTED DRAWING: None
