Resin film and method of producing resin film

Abstract

A resin film according to an embodiment of the present invention includes: a substrate film; and an antistatic layer formed on one side of the substrate film and including a binder resin and a conductive material. The binder resin includes a polyurethane-based resin; the antistatic layer has an arithmetic average surface roughness Ra of 10 nm or more; and the conductive material includes a conductive polymer.

What is claimed is: 
     
         1 . A method of producing a resin film, comprising:
 forming, on one side of a substrate film, an antistatic layer with a resin composition comprising a polyurethane-based resin and a conductive polymer; and   stretching the substrate film,   the antistatic layer having an arithmetic average surface roughness Ra of 10 nm or more and 100 nm or less after the stretching.
