よびその製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to indium acetylacetonate ethylacetoacetate useful for forming transparent conductors and a method for producing the same.

大してきている。BACKGROUND OF THE INVENTION In recent years, indium oxide films have come to be used as transparent conductive films for liquid crystal devices, and the range of applications has been expanding to take advantage of the properties of indium as a metal.

点を有する。 Methods for forming such an oxide film include a chemical spray method, a vacuum evaporation method, a screen printing method, and the like. Although the chemical spray method is advantageous in obtaining a film with a relatively large area, it is economically disadvantageous because extra steps such as etching are required to obtain a film with a fine and complex shape. The vacuum evaporation method has recently developed into a mask evaporation method and no longer requires etching, but since it is a batch method, it is not suitable for mass production. The screen printing method has the advantage that it does not have the above-mentioned problems, can easily obtain a desired shape by printing and firing, and does not require waste liquid treatment associated with etching.

In addition, when made into a paste, it has the disadvantage of being relatively easily chemically changed, such as promoting gelation of the paste.For this reason, the life of the paste containing indium organic acid is short, and the workability during screen printing is It is the cause of deterioration.
