Pressure-sensitive adhesive layer, optical film provided with pressure-sensitive layer, optical laminate, and image display device

Abstract

A pressure-sensitive adhesive layer formed from a pressure-sensitive adhesive composition containing, as monomer units, at least a (meth)acrylic polymer (A) that contains an alkyl (meth)acrylate, and a silicon compound (B), wherein: the silicon compound (B) is an organopolysiloxane compound; and when a laminate, in which a pressure-sensitive adhesive layer of a polarizing film provided with a pressure-sensitive adhesive layer having the pressure-sensitive adhesive layer and a polarizing film is laminated to an indium-tin composite oxide layer on a transparent conductive substrate having a transparent substrate and the indium-tin composite oxide layer, has been autoclaved for 15 minutes at 50° C. and 5 atm, and then the pressure-sensitive adhesive layer has been peeled away, the ratio of elemental silicon relative to the total of elemental carbon, nitrogen, oxygen, silicon, indium, and tin detected by X-ray photoelectron spectroscopy is 0.5-5 atomic % in the surface of the indium-tin composite oxide layer.
