  • Patent number: 7119218
    Abstract: The present invention provides a low melting point tin salt of aliphatic monocarboxylic acid obtained by a process comprising, reacting an aliphatic monocarboxylic acid having 4 to 30 carbon atoms or its salt and an inorganic tin compound so as to prepare a tin salt of aliphatic monocarboxylic acid, and bringing the tin salt in contact with an oxygen supplying substance.
    Type: Grant

  • Patent number: 7018462
    Abstract: The present invention provides an organic acid metal salt obtained by reacting a saturated monocarboxylic acid or its salt and an inorganic magnesium compound. The saturated monocarboxylic acid or its salt contains at least 97 wt % of a saturated monocarboxylic acid having 4 to 10 carbon atoms or its salt, and the organic acid metal salt contains at least 99 wt % of an organic acid magnesium salt. This organic acid metal salt consists essentially of an organic acid magnesium salt, and has excellent solubility in an alcohol solvent or a mixed solvent containing at least 5 wt % of an alcohol solvent and excellent temporal stability when being formed into a coating liquid for forming a magnesium oxide film. A coating film obtained from this coating liquid has excellent uniformity and provides a highly transparent magnesium oxide film having a thickness suitable for practical use by baking.

  • Patent number: 6911072
    Abstract: 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. The magnesium carboxylate content 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 wherein the magnesium carboxylate, the surfactant, and the polyhydric alcohol compound are dissolved in the solvent.
