    Abstract: A method for producing a pressure-sensitive adhesive layer-carrying optical film includes the step of applying, over the optical film, a coating liquid for anchor layer comprising a mixed solvent comprising 10 to 100% by weight of water and 90 to 0% by weight of an alcohol, and a polyoxyalkylene-group-containing polymer so as to give an applied-coat thickness before drying of 20 μm or less; and next drying the workpiece under drying conditions satisfying both of the following requirements (1) and (2): (1) the drying temperature T is from 40 to 70° C., and (2) a value obtained by multiplying the drying temperature T (° C.) by the drying period H (seconds), T×H, satisfies: 400≦(T×H)≦4000, thereby removing the mixed solvent to form the anchor layer.

    Abstract: A pressure-sensitive adhesive layer attached polarizing film of invention includes a polarizing film; and a pressure-sensitive adhesive layer provided on the polarizing film, wherein the polarizing film comprises a polarizer and a transparent protective film provided on only one side of the polarizer, the pressure-sensitive adhesive layer is provided on a side of the polarizer opposite to the side on which the transparent protective film is provided, and the pressure-sensitive adhesive layer is made from a pressure-sensitive adhesive composition including a (meth)acryl-based polymer (A), an onium-anion salt (B1), and an alkali metal salt (B2). The pressure-sensitive adhesive layer attached polarizing film has a pressure-sensitive adhesive layer possessing an antistatic function and satisfactory durability even after a humidity test under severe conditions and is less prone to degradation of optical properties even after a humidity test under severe conditions.
