Title:

FILM LAMINATE METAL SHEET, SUBSTRATE FOR FLEXIBLE DEVICES, AND SUBSTRATE FOR ORGANIC EL DEVICES

Document Type and Number:

WIPO Patent Application WO/2020/137783

Kind Code:

A1

Abstract:

A film laminate metal sheet according to the present invention is coated, on at least one surface thereof, with a resin film, wherein the arithmetic mean height Sa0 on the surface of the resin film is 3.0 nm or less, and the arithmetic mean height change ratio \{(Sa1/Sa0) × 100\} is 80 to 120% inclusive wherein Sa1 represents the arithmetic mean height of the surface of the resin film after the resin film is heat-treated at 100°C. It is preferred that the ten-point height S10z0 of the surface of the resin film is 50 nm or less. It is preferred that the ten-point height change ratio \{(S10z1/S10z0) × 100\} falls within the range from 80 to 120% inclusive, wherein S10z1 represents the ten-point height of the surface of the resin film after the resin film is heat-treated at 100°C.
