Abstract
A transparent conductive film having a transparent resin film containing a cyclic olefin resin, an undercoating layer formed on the transparent resin film, and a conductive layer and having a thermal dimensional change rate in hot water at 100° C. for 60 seconds of from 0.01 to 0.2%, which shows excellent adhesion between the transparent resin film and the conductive layer.
Claims11
A transparent conductive film containing a transparent resin film, an undercoating layer formed on the transparent resin film, and a conductive layer formed on the transparent resin film, wherein:
- the transparent resin film comprising a cyclic olefin resin,
- the transparent conductive film has a thermal dimensional change rate in hot water at 100° C. for 60 seconds of from 0.01 to 0.2%, and
- the transparent conductive film has an in-plane variation in the thermal dimensional change rate in hot water at 100° C. for 60 seconds of from 1 to 10%.
A transparent conductive film that is produced by forming a transparent resin film comprising a cyclic olefin resin, and forming an undercoating layer and a conductive layer on the transparent resin film, wherein the forming of the transparent resin film comprises extruding a molten resin comprising the cyclic olefin resin to form a sheet, and the extruding comprises imparting thickness unevenness to the sheet of the molten resin.
A touch panel comprising a transparent conductive film comprising a transparent resin film, an undercoating layer formed on the transparent resin film and a conductive layer formed on the transparent resin film, wherein the transparent resin film comprises a cyclic olefin resin, the transparent conductive film has a thermal dimensional change rate in hot water at 100° C. for 60 seconds of from 0.01 to 0.2%, and the transparent conductive film has an in-plane variation in the thermal dimensional change rate in hot water at 100° C. for 60 seconds of from 1 to 10%.
