PROBLEM TO BE SOLVED: To provide an adhesive tape suitably used for fixation of an optical film and having high constant load release property and high strain stress resistance to an adherend.SOLUTION: There is provided an adhesive tape having a polymer component containing 60 wt.% or more an acrylic polymer obtained by a living radical polymerization of at least a monomer mixture containing an acrylic alkylester monomer having 8 alkyl group carbon atoms and a crosslinkable functional group-containing monomer and having weight average molecular weight of 300,000 to 2,000,000 and molecular weight distribution (Mw/Mn) of 1.05 to 2.5 and an adhesive layer containing a crosslinker, where the content of the acrylic alkylester monomer having 8 alkyl group carbon atoms in the monomer mixture is 60 wt.% or more and gel fraction of the adhesive layer is 50 wt.% or less.SELECTED DRAWING: None |
