Process for producing phase retarder film.

摘要

A process for producing a phase retarder film, which comprises laminating a heat-shrinkable film on at least one side of a uniaxially stretched thermoplastic resin film so that the heat shrinkage axis direction of said heat-shrinkable film becomes perpendicular to the stretching axis direction of said uniaxially stretched thermoplastic resin film, subjecting the resulting laminate to heat shrinkage, and then peeling and removing the heat-shrinkable film. An object of the present invention is to provide a process for providing a phase retarder film having a desired R40/R0 value and a desired retardation value, easily and at a high efficiency.
