Japanese Patent JP6644128

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) the total 100 pts.wt. of at least one alkyl (meth) acrylate monomer with a C1-C14 alkyl group, 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 at least one a hydroxyl group-containing copolymerizable vinyl monomer of 0.1-5 pts.wt. Of (A), methyl acrylate monomers are 20-60 pts.wt.; (D) a crosslinker is contained by 0.01-5 pts.wt.; an adhesive layer has a thickness of 1 μm-20 μm and a refractive index of 1.47-1.50.SELECTED DRAWING: None
