Title:
INSULATING FILM-COATED METAL FOIL
Document Type and Number:
WIPO Patent Application WO/2013/012051
Kind Code:
A1
Abstract:
An insulating film-coated metal foil having on one or both surfaces thereof an organic-inorganic hybrid layer containing dimethylsiloxane and a metalloxane comprising a metal other than Si. Relative to the concentration [Si]1/4t of the Si at a depth of 1/4t from the surface of the organic-inorganic hybrid layer in the thickness direction of the hybrid layer, the concentration [Si]3/4t of the Si at a depth of 3/4t from the surface of the organic-inorganic hybrid layer in the thickness direction of the hybrid layer satisfies [Si]1/4t<[Si]3/4t, and ([Si]3/4t-[Si]1/4t)/[Si]3/4t is 0.02-0.23. Provided is a metal foil that can be used in solar cell substrates, flexible circuit substrates, etc., that exhibits surface flatness, pliability, insulating properties and thermal resistance properties, and that has a layer having a surface which is not susceptible to scratching by processes in which substrates are handled, such as conveyance and transshipment.
