Abstract

Problems to be Solved: To provide a metal foil coil with a planarization film, with which an electronic device can be formed by a roll to roll process. Solution: A quick curable coating liquid for a planarization film prepared by adding into an organic solvent, with respect to 1 mol of a phenyltrialkoxysilane, 0.1 mol to 1 mol of acetic acid and 0.005 mol to 0.05 mol of organic tin as a catalyst, hydrolyzing the silane with 2 mol to 4 mol of water, then distilling away the organic solvent at a temperature of 160° C. to 210° C. under reduced pressure to yield a resin, and dissolving the resin in an aromatic hydrocarbon solvent, is coated on a metal foil coil to a film thickness of 2.0 μm to 5.0 μm. When an insulation coating is provided on a metal foil coil before a planarization film is formed, high reliability for insulation can be obtained. When a stainless steel foil provided with a reflection film is used, a highly efficient light emitting device can be obtained.
