Patent ID: 8388798

Claim:
A pressure-sensitive adhesive comprising a pressure-sensitive adhesive material prepared by irradiating with an active energy beam a pressure-sensitive adhesive resin comprising (A) an acrylic copolymer and (B) an active energy beam-curable compound, wherein said pressure sensitive adhesive resin comprises fine particles having an average particle diameter of 0.1 to 20 μm dispersed therein, wherein: the pressure-sensitive adhesive has a storage elastic modulus (G′) at 23° C. of 0.3 to 15 MPa, and a haze value of 5% or more, a content ratio of component (A) to component (B) is 100:10 to 100:40 in terms of a mass ratio, and the active energy beam-curable compound is a multifunctional (meth)acrylate base monomer having a molecular weight of less than 1000 and having a cyclic structure.
