本発明は、透明導電体形成に有用なインジウム
トリスアルキルアセトアセテートおよびその製造
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 trisalkyl acetoacetate useful for forming transparent conductors and a method for producing the same.
従来の技術
近年インジウムの酸化物被膜が液晶素子の透明
導電膜に使用されるようになり、インジウムの金
属としての特性を利用すべく、その応用範囲が拡
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.
このような酸化物被膜の形成方法には、化学ス

により容易に得ることができ、しかも、エツチン
グ処理にともなう廃液処理の必要もないという利
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.

Indium trisacetylacetonate [In
(acac) 3 ] is used.
有機酸インジウムは一般に加水分解しやすく、
またペーストとした場合、ペーストのゲル化を促
進する等、比較的容易に化学変化するという欠点
を持つており、このため、有機酸インジウムを含
有するペーストの寿命が短く、スクリーン印刷時
の作業性を悪くする原因となつている。 Indium organic acids are generally easy to hydrolyze;
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.
