摘要
Disclosed are: a stretched film obtained by uniaxially stretching a laminated film which comprises a base film and a polyvinyl alcohol resin layer laminated on one surface of the base film, wherein the base film has a multilayer structure of resin layers including two resin layers which comprise different resins from one another; a polarizing stretched film obtained by imparting polarizing performance to the stretched film; and a method for producing a polarizing plate using the polarizing stretched film. It is preferable that the resins constituting the above-described two resin layers show different phase transition temperatures from one another.
