A pressure-sensitive adhesive layer-bearing polarizing film for a transparent conductive coating, includes an iodine-based polarizing film and a pressure-sensitive adhesive layer placed on at least one side of the polarizing film, wherein the iodine-based polarizing film includes an iodine-based polarizer containing 1 to 14% by weight of iodine and/or iodide ions and having a thickness of 2 to 40 &#x3bc;m and a transparent protective film provided on at least one side of the polarizer and having a water-vapor permeability of 1,000 g/(m&#xb7;24 hours) or less at 60&#xb0; C. and 90% R.H., and the pressure-sensitive adhesive layer has a saturated water content of 3.5% by weight or less at 60&#xb0; C. and 90% R.H.

Pressure-sensitive adhesive layer-bearing polarizing film for transparent conductive coating, laminate, and image display device

Provided is a pressure-sensitive adhesive layer for a transparent conductive film having a patterned transparent conductive thin film, which has transparent as the pressure-sensitive adhesive layer for transparent conductive film and can prevent the patterned transparent conductive thin film from degrading the appearance of the conductive film. A pressure-sensitive adhesive layer for a transparent conductive film having a patterned transparent conductive thin film, wherein the pressure-sensitive adhesive layer is made from an acrylic pressure-sensitive adhesive composition containing: 100 parts by weight of an acryl-based polymer obtained by polymerization of a monomer component including an alkyl(meth)acrylate; and 30 to 150 parts by weight of a styrene-based oligomer, the pressure-sensitive adhesive layer has a refractive index of 1.50 or more, the pressure-sensitive adhesive layer has a haze of 2% or less as measured at a thickness of 30 &#x3bc;m.

Pressure-sensitive adhesive layer for transparent conductive film, transparent conductive film with pressure-sensitive adhesive layer, transparent conductive laminate, and touch panel

A transparent conductive film which comprises: a transparent adhesive layer; a first polycycloolefin film laminated on one surface of the transparent adhesive layer; a second polycycloolefin film laminated on the other surface of the transparent adhesive layer; a plurality of first transparent electrode patterns formed on the first polycycloolefin film; and a plurality of second transparent electrode patterns formed on the second polycycloolefin film. The transparent conductive film shows little color phase irregularity when observed from any direction.
