Abstract
Provided are a separator-attached adhesive layer structure which comprises a separator having moderate light peelability with respect to an adhesive layer and exhibits excellent processability and durability, and a production method therefor. The production method comprises: a first step of forming a layer of an adhesive composition containing a (meth)acryl-based polymer, a peroxide and a phenolic antioxidant, on a release treatment surface of a separator subjected to a release treatment; and a second step of, after completion of the first step, heating the adhesive composition to cause cross-linking therein so as to be formed as an adhesive layer.
