Abstract:
1. An aqueous coating liquid for forming a magnesium oxide film comprising: (a) a magnesium carboxylate derived from a carboxylic acid having 1 to 6 carbon atoms; (b) a surfactant; (c) a polyhydric alcohol compound; and (d) a solvent made substantially of water; wherein the magnesium carboxylate is contained in a ratio of 5 wt % or more and 50 wt % or less; the surfactant is contained in a ratio of 0.01 wt % or more and 2.5 wt % or less; and the polyhydric alcohol compound is contained in a ratio of 0.05 wt % or more and 40 wt % or less, based on a weight of the entire coating liquid, a content of the magnesium carboxylate is the same with or larger than that of the polyhydric alcohol compound, and a total weight of the magnesium carboxylate and the polyhydric alcohol compound is 80 wt % or less of the weight of the entire coating liquid, and the magnesium carboxylate, the surfactant, and the polyhydric alcohol compound are dissolved in the solvent.
