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, anda 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 DEG C and 5 atm, and then the pressure-sensitive adhesive layer has been peeled away, the ratio ofelemental 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. This pressure-sensitive adhesive layer has reworkability with respect to a transparent conductive layer and high durability.

Description

technical field

[0001] The present invention relates to an adhesive layer, an optical film with an adhesive layer, and an optical laminate. Moreover, this invention relates to the said optical film with an adhesive layer, image display devices, such as a liquid crystal display device, an organic electroluminescent display device, and PDP using the said optical laminated body. As the above-mentioned optical film, a polarizing film, a retardation film, an optical compensation film, a brightness improving film, and an optical film in which the above-mentioned films are laminated can be used. Background technique

[0002] For liquid crystal display devices and the like, it is essential to arrange polarizing elements on both sides of the liquid crystal cell from the viewpoint of the image forming method, and usually a polarizing film is bonded thereto. In addition, in order to improve the display quality of displays, various optical elements other than polarizing films have begu...
