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.
