Abstract
An object of the invention is to provide a pressure-sensitive adhesive optical film-peeling method capable of easily detaching the pressure-sensitive adhesive optical film from a glass substrate with no damage to the glass substrate or no adhesive deposit on the glass substrate, and to provide a pressure-sensitive adhesive optical film suitable for use in such a peeling method. The invention is directed to a method for peeling a pressure-sensitive adhesive optical film from an optical film-carrying glass substrate including a glass substrate and the pressure-sensitive adhesive optical film bonded thereto, which includes: exposing the optical film-carrying glass substrate to an environment at a temperature of 40 to 98° C. and a relative humidity of 60 to 99% for three minutes or more; and then peeling the pressure-sensitive adhesive optical film from the glass substrate under the environment.
