<p>PROBLEM TO BE SOLVED: To provide satisfactory reserving property and film characteristics and to facilitate viscosity adjustment by dissolving an organic indium compound and an organic tin compound in a solvent to be a coating liquid for transparent electrically conductive film. SOLUTION: An organic indium compound to be used is an indium-disoap expressed by structural formula In (OH)(OCOR)2, R is preferably 1-19C alkyl groups that may be a branch or straight chain and may be the same or different. The organic indium compound and a typical organic tin compound are dissolved in a solvent, that can dissolved them at near room temperature and does not react with both of them or hardly react when heated. When dissolved by a nonpolar solvent, the indium-disoap shows high viscosity even in a dilute solution and a high viscosity coating liquid can be obtained without using a thickener. Therefore, using by combining a suitable polar solvent enables the coating liquid to be adjusted easily to have a desirable viscosity without adding a thicker.</p> |
