The present invention relates to a transparent metal oxide coating formed on a substrate such as glass or ceramics, and more particularly to a transparent metal oxide coating in which the transparent coating is zinc oxide (ZnO). Generally, the main methods for forming ZnO transparent films are vacuum evaporation, chemical spraying, and dipping. Although the vacuum evaporation method has excellent film characteristics, it has problems in mass production, and further processes such as etching are required to support patterning.
On the other hand, the chemical spray method and the dipping method have no problems in mass production, but have the same problems with patterning. As described above, the conventional methods have advantages and disadvantages, and cannot necessarily be called superior methods. The present invention was made in order to provide a printing paste that can be screen printed and form a ZnO film upon firing. It is characterized by containing a zinc compound in the paste.
That is, a paste is composed of the organic zinc compound, an organic solvent, and a viscous agent. The organic zinc compound is preferably chemically stable, for example, zinc bisacetylacetonate (Z(acac) 2 ).
Examples of organic solvents for dissolving organozinc compounds include high-boiling alcohols such as terpineol, 2-ethylhexanol, and benzyl alcohol, high-boiling esters such as benzyl acetate and dimethyl phthalate, carbitol, butyl carbitol, and butyl cellosolve. High boiling point organic solvents such as high boiling point alcohol ethers are used, and cellulose compounds such as nitrocellulose and ethyl cellulose are used as viscosity agents. Using the paste made in this way, screen printing is performed using a screen plate patterned into the desired shape, and after pre-drying, a ZnO transparent film is formed in the desired shape by baking at a temperature of 400℃ or higher. Ru. This film is not only transparent, but also has high film strength and relatively high insulation properties. Furthermore, by appropriately controlling the amount of Zn(acac) 2 contained in the paste, a film with a thickness of 2500 Å or less can be freely formed. The ZnO transparent film and ZnO transparent film forming paste of the present invention have slightly different properties from conventional ones, and can be applied in many fields. Hereinafter, a detailed explanation will be given based on examples. Example 1 Bisacetylacetonate Zn (acac) 2 , a mixed organic solvent mixed with butyl carbitol: butyl cellosolve: benzyl acetate at a ratio of 3:2:5, and 15 wt% of nitrocellulose as a viscosity agent.
Added to make the paste viscosity 80000cp, and finally Zn
The content of (acac) 2 is 1 to 20wt relative to the total amount of paste.
%, and pastes were prepared for each.
Using this paste, screen printing was performed on a soda glass substrate using a stainless steel net 250 mesh screen plate, and after pre-drying at 150℃ for 20 minutes,
After baking at ℃ for 30 minutes, the thickness and other characteristics of each film were examined, and the results are shown in the table below.
Note that in the table, an x mark indicates a test result that was judged to be poor, a △△ mark indicates a test result that was judged to be somewhat poor, a ◯ mark indicates a test result that was judged to be good, and a - mark indicates a test result that was not measurable. Moreover, the light transmittance (visible part min.) indicates the lowest transmittance among the wavelengths of 380 to 800 nm.

リーン印刷が可能なペーストを提供することがで
き、それによつて量産に適し、パターン化が容易
な透明被膜が得られる。[Table] Based on the above results, the Zn (acac) 2 content is 5~
It can be seen that when the content is 15 wt%, a film with good transparency, high film strength and electrical insulation properties, and a thickness of about 500 to 2000 Å can be freely formed. Example 2 Using a mixture of 2-ethylhexanol:benzyl alcohol = 1:3 as the organic solvent and ethyl cellulose as the viscosity agent, the addition amount was 12 wt%, the paste viscosity was adjusted to 80,000 cp, and the same experiment as in Example 1 was carried out. I did this and got almost the same results. The present invention has the above-described configuration, and can provide a paste that can be screen printed, thereby obtaining a transparent film that is suitable for mass production and easy to pattern.
