METALLIZED FILM AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2021/206039

A1

The present invention addresses the problem of providing: a metallized film which shows a small degree of change in resistance and chromaticity before and after a moisture resistance test; and a method for producing the metallized film. The problem can be solved by a metallized film which comprises a film and a copper layer and an antirust layer arranged on at least one surface of the film in this order as observed from the film side, in which the antirust layer contains at least one component selected from the group consisting of metal titanium, a titanium oxide and a mixture thereof, the change ratio of the surface resistance after a lapse of 3 days under an environment of 85°C and 85% RH is 20% or less, and the color difference ΔE after a lapse of 3 days under the above-mentioned environment is 6.5 or less.
