ADHESION COMPOSITION, AN ADHESIVE AND ADHESION SHEET

摘要

Provided are an adhesive composition, an adhesive, and an adhesive sheet having improved durability, suitable for an optical member such as a polarizing plate. The adhesive composition contains: a (meth) acrylic acid ester polymer (A) containing 1.5 mass% or more of a monomer with hydroxyl group as a monomer unit forming the polymer; an isocyanate-based crosslinking agent (B); a silane coupling agent (C) with a mercapto group as a functional group reacting with an organic material; and an active energy ray-curable component (D).
