Methods for manufacturing resin films, metal-coated laminates, circuit boards, and resin films.

Abstract

The purpose of this invention is to provide a resin film that can maintain sufficient adhesion strength to other materials even under high-temperature conditions. This invention relates to a resin film comprising at least a fluororesin, wherein the water contact angle of the surface of the resin film is 55° to 105°, and before and after heat treatment at 180°C for 10 minutes, the color difference Δb* of the surface of the resin film in the CIE1976 (L*, a*, b*) color space, measured according to JIS Z8781-4:2013, is 0.5 or less, and the color difference ΔE* is 0.8 or less. none
