  • Patent number: 9177690
    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 ¼t 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 ¾t 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.

  • Patent number: 7951458
    Abstract: A coating solution for forming a flat-surface insulating film, which is a coating solution obtained by dissolving a poly(diorgano)siloxane A having a mass average molecular weight of 900 to 10,000 and a metal alkoxide B in an organic solvent C and further adding water, wherein the molar ratio A/B of the poly(diorgano)siloxane A to 1 mol of the metal alkoxide B is from 0.05 to 1.5, the organic solvent C has a hydroxyl group, the solubility of water in 100 g of the organic solvent C is from 3 to 20 g, and the molar ratio C/A of the organic solvent C to 1 mol of the poly(diorgano)siloxane A is from 0.05 to 100.
