Abstract
Provided are a pressure-sensitive adhesive for polarizing plates which can apply a polarizing plate on a liquid crystal cell with good adhesion and has the characteristic that a liquid crystal display device obtained therefrom is less liable to cause light leakage even under the environment of high temperature and high humidity and which has a removability and a polarizing plate with the above pressure-sensitive adhesive and a production process for the same. The pressure-sensitive adhesive for polarizing plates is prepared by irradiating a pressure-sensitive adhesive material comprising (A) an acrylic base polymer comprising a monomer having a carboxyl group in a monomer composition ratio of 0.5 mass % or less and (B) an active energy beam-curable compound with an active energy beam and it has a storage elastic modulus (G') of 0.3 MPa or more at 23° C.
