PLASTIC FILM WITH TRANSPARENT CONDUCTING FILM AND PROTECTIVE FILM

摘要

PROBLEM TO BE SOLVED: To manufacture a transparent conducting film in which dimension change and curling caused by thermal treatment during the process of forming a touch panel or the like are not generated. SOLUTION: In a plastic film with a transparent conducting film formed on one face and a protective film formed on a plastic film face opposite to the face on which the transparent conducting film is formed, the protective film is formed of a first film having 0.5% heat shrinkage coefficient or less both in the MD and TD directions after heating at 150 deg.C for 30 minutes and a second film having the linear expansion coefficient provided with 40 ppm/ deg.C difference or less from the linear expansion coefficient of the plastic film with the transparent conducting film and the protective film, and the first film and the second film are formed on the plastic film in the above order.
