ABSTRACT:
The present invention relates to a process for producing a pressure-sensitive adhesive layer, which includes irradiating a photopolymerizable acrylic pressure-sensitive adhesive composition layer provided between two films with an active energy beam to polymerize the photopolymerizable acrylic pressure-sensitive adhesive composition layer, in which the polymerization is performed while a layer of a composition for preventing polymerization inhibition which is curable with an active energy beam in the atmosphere is provided on a side surface of the photopolymerizable acrylic pressure-sensitive adhesive composition layer. According to the process for producing a pressure-sensitive adhesive layer of the present invention, owing to the construction as discussed above, it is possible to reuse a film. Moreover, it is possible to prevent a lowering in the cohesive force in the side surface of the thus formed pressure-sensitive adhesive composition layer caused by a lowering in the polymerization degree in the side surface of the photopolymerizable acrylic pressure-sensitive adhesive composition layer during the photopolymerization.
