Abstract

There is provided a pressure sensitive adhesive displaying sufficient adhesive force to the surface of PMMA under a wide range of temperatures including ambient, low, and high temperatures, and also an adhesive tape having an adhesive layer including the pressure sensitive adhesive. There is provided a pressure sensitive adhesive comprising a polymer obtained by polymerizing 100 mass parts of a monomer mixture comprising: a monomer component 1 comprising an acrylate mixture selected from an aliphatic alkyl(meth)acrylate having a carbon number of 4-6 and an aliphatic alkyl(meth)acrylate having a carbon number of 7-12; a monomer component 2 comprising an amide group-containing vinyl monomer; a monomer component 3 comprising an ester of a non-tertiary aromatic alcohol and (meth)acrylic acid, or an ester of a non-tertiary alicyclic alcohol and (meth)acrylic acid; and a monomer component 4 comprising (meth)acrylic acid.
