<p>PROBLEM TO BE SOLVED: To provide a film improved in description resistance, alkali resistance and adhesion by making the linearity lower than a specified value and making the retardation value lower than a specified value after the polyacetal pen of a specified diameter is used and reciprocatively moved plural times with a specified load. SOLUTION: Concerning a touch panel sample, a transparent conductive film 3 is laminated through a spacer 2 onto glass 4 with conductive film 1 and further, a polarizing film 5 with hard coat is laminated through an adhesive layer 4 onto the film 3. When measuring the linearity of the transparent conductive film 3 to be used as the transparent electrode of a touch panel, the film is reciprocatively moved 100,000 times with the load of 250 g (at the speed of 3 reciprocation per second for the distance of 35 mm for one side) while using a polyacetal pen 6 having the diameter of 8 mm. After this transparent conductive film 3 is reciprocatively moved 100,000 times, its linearity is lower than 1.45% and its retardation value is lower than 15 nm.</p> |
