Title:
光透過性導電性フィルム、その製造方法及びその用途
Document Type and Number:
Japanese Patent JP6687389
Kind Code:
B2
Abstract:
The present invention addresses the problem of providing a light-transmissive electroconductive film that has improved (1) degree of suppression of a pattern visibility phenomenon when a light-transmissive electroconductive layer is patterned, and (2) haze value balance. Provided is a light-transmissive electroconductive film which contains (A) a light-transmissive support layer, (B) a protrusion layer, and (C) a light-transmissive electroconductive layer, the protrusion layer (B) being arranged on at least one surface of the light-transmissive support layer (A) either directly or with one or more other layers interposed therebetween, the light-transmissive and electroconductive layer (C) being arranged on at least one surface of the light-transmissive support layer (A) either directly or with one or more other layers therebetween, and if arranged on the same surface as the protrusion layer (B), the light-transmissive electroconductive layer (C) is arranged with at least the protrusion layer (B) interposed therebetween, wherein: the surface of the protrusion layer (B) that is on the side opposite the light-transmissive support layer (A) has a plurality of protrusions having a convex curve; and, in a length (X) of a straight line projected toward the direction of a principal surface of the film in a cross-sectional view of the protrusions (where only foot portions of the protrusions having an incline of 3° or more relative to the direction of the principal surface of the film are considered to be protrusions) on a plane orthogonal to the principal surface of the film, the proportion of the cross-sectional view that is occupied by the sum length of the projected straight line of those portions that have an incline of 3° or more relative to the direction of the principal surface of the film is 70% or more.
