Embodiment
[0117] Hereinafter, although the Example of this invention is demonstrated more concretely, it should not be construed as being limited to these Examples.
[0118] The abbreviations of the compounds used in this example are as follows.
[0134] 11.9 g of AN and 2.8 g of water were added to a 300 mL flask and stirred to dissolve AN. BCS25.8g and TTE12.4g were added there, and it stirred at room temperature for 30 minutes. Thereafter, 14.7 g of TEOS and 7.5 g of MPMS were added, followed by further stirring at room temperature for 30 minutes. 120.5 g of HG and 4.4 g of BCS were mixed in this solution to obtain a solution (K1).

Abstract
The present invention provides a method for producing a coating liquid for a metal oxide film that can obtain sufficient hardness even in low-temperature firing without a solvent replacement step, and has good printability and in-plane uniformity in a flexographic printing method , the coating liquid for metal oxide film and the metal oxide film produced by this method. The method for producing a coating liquid for a metal oxide film includes the following steps: a first step of hydrolyzing a first metal alkoxide in the presence of a metal salt and an organic solvent to obtain a solution of the first step; A second step of adding a second metal alkoxide having lower reactivity than the first metal alkoxide, hydrolyzing and condensing to obtain a solution of the second step, and a third step of adding a precipitation inhibitor to the solution of the second step.
Description
technical field [0001] The present invention relates to a coating liquid for a metal oxide film and a method for producing the same, and more particularly, to a film that can form a film having excellent mechanical strength and an arbitrary refractive index on substrates such as glass, ceramics, metals, and plastics. A coating liquid for a metal oxide film with sufficient hardness and a method for producing the same can be obtained even by low-temperature firing. Background technique [0002] Conventionally, inorganic coatings have been formed on the surfaces of substrates such as glass, ceramics, metals, and plastics for various purposes. By forming an inorganic coating film on the surface of the substrate, electrical properties, optical properties, chemical properties, mechanical properties, and the like can be imparted to the substrate. Therefore, these inorganic films are put into practical use as conductive films, insulating films, selective light-transmitting or absor...
