Abstract: Embodiments are directed to a method for processing a film, which includes: (A) a step wherein protective films are temporarily bonded to both surfaces of a film that is a material to be processed, thereby obtaining a film to be processed to both surfaces of which the protective films are bonded; and (B) a step wherein the film to be processed to both surfaces of which the protective films are bonded is cut using a laser having a wavelength at which the protective films have an absorbance of 50% or more. Other embodiments are directed to a method for processing a film, which includes: (A) a step wherein protective films are temporarily bonded to both surfaces of a film that is a material to be processed, thereby obtaining a film to be processed to both surfaces of which the protective films are bonded; and (B′) a step wherein the film to be processed to both surfaces of which the protective films are bonded is cut using a laser having a wavelength at which the film to be processed has an absorbance of 50% or more and the protective films have an absorbance of 50% or more.

Abstract: The present invention pertains to a process for producing an article from a layered hard coat object including a hard coat layer and a transparent-resin film layer in this order from the outermost layer side, the process comprising: a step (A) in which a pressure-sensitive adhesive layer of a support having the pressure-sensitive adhesive layer on at least one surface thereof is temporarily applied to at least one surface of the layered hard coat object to obtain a temporarily support-bearing layered hard coat object; a step (B) in which at least one processing method selected from the group consisting of router processing, water-jet processing, laser processing, and punching is applied to the temporarily support-bearing layered hard coat object to cut the temporarily support-bearing layered hard coat object into a given shape, thereby obtaining a temporarily support-bearing cut article; and a step (C) in which at least one kind of energy selected from the group consisting of heat and actinic rays is applied to the temporarily support-bearing cut article to reduce the strength of tackiness between the support and the article to 2 N/2.5 cm or less.
