Title:
OPTICAL FILM, ELECTROCONDUCTIVE FILM, TOUCH PANEL, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/047359
Kind Code:
A1
Abstract:
The present invention provides: an optical film that has an easily adhesive layer having superior blocking properties and adhesiveness, as well as an exceptional surface configuration in which microparticles are kept from detaching; and an electroconductive film, a touch panel, and a display device that include this optical film. This optical film has a substrate comprising a cyclic olefin resin, and an easily adhesive layer disposed adjacent to the substrate, the easily adhesive layer containing a polyurethane resin having a glass transition temperature of 50°C or higher, microparticles of which the average particle size is 1.0 to 5.0 times the thickness of the easily adhesive layer, and a surfactant; the surfactant content being 0.7 to 8.0% by mass of the total amount of the easily adhesive layer.
