Patent ID: 7892394

Claim:
A pressure-sensitive adhesive comprising an active-energy irradiation cured mixture, wherein prior to curing: an uncured mixture comprises a pressure-sensitive adhesive resin, and an antistatic agent, the pressure-sensitive adhesive resin comprises an acrylic copolymer (A), and an active energy beam-curable compound (B), and a content ratio of the acrylic copolymer (A) to the active energy beam-curable compound (B) in the pressure-sensitive adhesive resin ranges from 100:5 to 100:50 in terms of a mass ratio; wherein the pressure sensitive adhesive has a storage elastic modulus (G′) at 23° C. of 0.3 MPa or more, a charged voltage on a surface of a layer comprising the pressure-sensitive adhesive is 1.0 kV or less, the charged voltage being measured at 5 seconds after peeling off a release film attaching to the layer in an environment of 23° C. and a relative humidity of 50%; wherein the pressure sensitive adhesive storage elastic modulus (G′) at 23° C. is from 0.3 to 15 MPa; wherein the active energy beam-curable compound (B) is a multifunctional (meth)acrylate base monomer having a molecular weight of less than 1000; and wherein the multifunctional (meth)acrylate base monomer has a cyclic structure.
