To provide an adhesive layer for optical films, formed from a water-dispersed adhesive composition, having satisfiable optical properties and satisfying durability under heated and humid conditions.
There is provided the adhesive layer for optical films formed from the water-dispersed adhesive composition. The water-dispersed adhesive composition is an aqueous dispersion containing (A) a water-dispersion (meth)acrylic copolymer containing an alkyl (meth)acrylate and a carboxyl-containing monomer as monomer units, (B) a silane coupling agent and (C) inorganic particles bondable with the silane coupling agent (B). The content of the inorganic particles (C) is 1-50 pts.wt. in solid weight ratio based on 100 pts.wt. of the (meth)acrylic copolymer (A), and the adhesive layer has a haze value of ≤1% at a thickness of 20 μm.
