Abstract

PURPOSE:To obtain a pressure-sensitive adhesive polarizing plate having improved durability and useful for an electronic watch, by placing a pressure- sensitive adhesive layer composed of a specific acrylic polymer on a surface of a polarizing plate. CONSTITUTION:The objective polarizing plate is produced by coating a surface of a polarizing plate with a pressure-sensitive adhesive layer consisting of an acrylic polymer composed mainly of an alkyl (meth)acrylate having 1-12C alkyl group, containing <=15wt.% of a polymer component having a weight- average molecular weight of <=100,000 and containing >=10wt.% of a polymer component having a weight-average molecular weight of >=1,000,000. The thickness of the adhesive layer is preferably 10-300mum.
