    摘要： The disclosed a pressure sensitive adhesive for polarizing plates which has a storage elastic modulus (G′) at 23° C. of at least 0.3 MPa; a polarizing plate having a pressure sensitive adhesive; a process for producing the above polarizing plate which comprises sticking a polarizing plate on a tacky adhesive material layer formed on a releasing layer of a releasing sheet, and thereafter irradiating with an active energy beam from the releasing sheet side; an optical film which comprises a polarizing plate and a phase difference plate; and a process for producing the above optical film. The pressure sensitive adhesive and polarizing plate having the pressure sensitive adhesive are characterized in that they are capable of sticking with high durability, the polarizing plate to a and phase difference plate, and the resultant liquid crystal display unit is less liable to cause light leakage under the conditions of high temperature.
