Title:
透明導電性フィルム用保護フィルム及び積層体
Document Type and Number:
Japanese Patent JP6697876
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a protective film for a transparent conductive film capable of suppressing an increase in surface resistivity even under a high-temperature environment, and a laminate having a transparent conductive film.SOLUTION: The protective film for a transparent conductive film includes: a substrate having a first surface and a second surface; an antistatic layer provided on the first surface of the substrate; and an adhesive layer formed of an adhesive composition on the second surface of the substrate. The antistatic layer comprises an antistatic agent composition containing a polyaniline sulfonic acid and a polyanion-doped polythiophene as conductive polymer components and containing a polyester resin as a binder. The blending ratio (mass ratio) of the polyaniline sulfonic acid to the polyanion-doped polythiophene is 90:10-10:90. Preferably, the antistatic agent composition contains a melamine-based and/or isocyanate-based crosslinking agent as a crosslinking agent.SELECTED DRAWING: None
