いはセラミックスの保護膜を形成することが行われてい
る。Applying a protective thin film of metal or nonmetal for the purpose of improving decoration, corrosion resistance, and abrasion resistance has traditionally been done by so-called electroplating.
Surface oxidation treatments such as hot plating, spraying, infiltration, anodic oxidation, and chemical conversion treatments are performed. Furthermore, a protective film of glass or ceramics is formed by melting or sintering inorganic powder, such as by enameling.
しかし、保護膜としての効果を向上させることからも、
その膜厚は10μ〜数amと非常に厚く、保護膜として
の効果を十分に維持させたまま薄くすることは技術的に
困難であった。However, since it improves the effect as a protective film,
The film thickness is very thick, ranging from 10 μm to several am, and it is technically difficult to reduce the thickness while maintaining the effect as a protective film.

が低く、その効果が十分に発揮されない場合もあった。In addition, silicates are used to improve weather resistance, heat resistance, or affinity for surface modification of inorganic fine powders such as iron oxyhydroxide yellow pigments, titanium white pigments, and magnetic iron fine particles used as raw materials for magnetic recording media. This is carried out by hydrolysis of an aluminum compound, precipitation by a homogeneous precipitation method, hydrothermal treatment, or the like. However, with these methods, coexisting alkalis such as sodium ions, sulfate radicals, chloride ions, etc. tend to remain even after thorough washing with water, and therefore the purity of the coating film is low and its effectiveness may not be fully demonstrated.

, "Kiln" Vol. 95, p. 442 (1987)) Recently, with the development of advanced technologies such as electronics, new thin film forming methods have been developed, such as vacuum evaporation, molecular beam epitaxy, ion blating, These methods include sputtering and CVD, which are much thinner than conventional techniques and can also form thin films with new compositions and functions, but they require the use of expensive equipment or are not suitable for large areas or mass production.

In other words, many metal alkoxides are extremely easily hydrolyzed, so be careful of moisture in the atmosphere, solvent, etc., and dissolve them in alcohol etc. in a water-free atmosphere. By controlling the evaporation rate, humidity, etc. of the solvent, it is possible to produce glass in bulk, fibers, sheets, coating films, fine particles of glass, or amorphous materials.

As a result, they have improved the stability of the metal alkoxide solution, which is the starting material, against water. By doing so, we have achieved the present invention in which very transparent glass or thin films can be easily manufactured, and the manufacturing process is simple and inexpensive.

熱分解後にカーボンが残留し易くなる。The aluminum alkoxide compound of the present invention is, for example, AL(OR)3 in which R is an alkyl group having about 2 to 5 carbon atoms, or a part of R is substituted with an acetoacetyl group or the like. The aluminum alkoxide compound is treated with an organic solvent such as alcohols such as isofurohanol and n-phthanol, hydrocarbons such as n-hexane and n-heptane, alkylbenzenes such as toluene and xylene, esters such as ethyl acetate, and acetone. ,
After dissolving in a soluble solvent selected from ketones such as methyl ethyl ketone, compounds containing 1,3- or β-diketone groups, i.e. diketones such as acetylacetone, malonic acid and malonic acid derivatives such as diethyl malonate, Ethyl acetoacetate such as acetoacetic acid and ethyl acetoacetate is added by 0.1 to 10.0 times the mole, preferably 0.3 to 3.0 times the mole of the aluminum alkoxide compound. The stability of the metal alkoxide against water decreases, and if the amount is too large, carbon tends to remain after thermal decomposition.

This is to prevent sublimation and decomposition of metal alkoxides and to prevent carbon from remaining. However, if a large amount of water is added, a precipitate of aluminum hydrolysis will be formed, resulting in poor uniformity, which is undesirable. In other words, aluminum alkoxide, The range of water addition at which precipitation occurs varies depending on the reactivity of the diketone compound and water, so it cannot be specified.
For example, when an equimolar amount of ethyl acetoacetate is added to an aluminum alkoxide compound, no precipitate is formed even when up to 3.0 mol of water is added, and with diethyl malonate, no precipitate is formed even when up to 1.0 mol of water is added. .

る。Furthermore, the effects of the present invention are remarkable in surface modification of inorganic pigments. In other words, according to the standard method, inorganic pigments or their raw material powders are synthesized by a so-called wet method using water as a medium, washed with water, dried, and fired as necessary, but pigments absorb a lot of moisture in the atmosphere. This is always the case. Therefore, when a pigment is added to a metal alkoxide solution, hydrolysis occurs due to adsorbed water, and the uniformity of the slurry decreases. However, by adding a diketone group-containing compound to the metal alkoxide solution in advance, the uniformity of the slurry can be improved. can be improved.

Metal pigments such as aluminum flakes and bronze powder have a strong oxide film on the surface, and a transparent layer is formed on the oxide film. By forming a thin coating film containing high alumina, it is possible to improve chemical resistance and weather resistance while maintaining the excellent color tone inherent to metal pigments.'' (3) Specification, page 9, lines 19 to 20. Delete the words "Add 1 molar amount of diethyl malonate" in the line.
(4)明細書第12頁第17行にro、05倍モル添加
しjとあるのをro、osモル添加し」と訂正する。(4) On page 12, line 17 of the specification, the text ``ro, 05 times the molar addition and j'' is corrected to ``ro, os molar addition''.
(5)明細書第13頁第1行に「該表面積改質」とある
のを「該表面改質」と訂正する。(5) In the first line of page 13 of the specification, "the surface area modification" is corrected to "the surface modification."
(6)明細書第13頁第11行に「透過がた」とあるの
を「透過型」と訂正する。(6) On page 13, line 11 of the specification, the phrase "transparent type" is corrected to "transparent type."
