Pressure-sensitive adhesive composition, pressure-sensitive adhesive layer, pressure-sensitive adhesive-layer—attached polarizing film, and image display device
A pressure-sensitive adhesive composition is disclosed making it possible that even when a polarizing film and a transparent conductive layer are laminated over each other to interpose a pressure-sensitive adhesive layer there between, this pressure-sensitive adhesive layer is formed as a pressure-sensitive adhesive layer capable of restraining the transparent conductive layer from being corroded, and further restraining a rise in the surface resistance of the transparent conductive layer, and a deterioration in the external appearance of this layer. Also disclosed are a pressure-sensitive adhesive layer made from the pressure-sensitive adhesive composition, a pressure-sensitive-adhesive-layer-attached polarizing film, and an image display device using the pressure-sensitive-adhesive-layer-attached polarizing film. The pressure-sensitive adhesive composition includes a (meth)acryl-based polymer (A) and a conductive agent (B) having a molecular weight of 380 or more.
