  • Method for producing In2O3—SnO2 precursor sol
    Patent number: 6235260
    Abstract: The invention relates to a method for forming a transparent conductive thin film of In2O3—SnO2 on a surface of a plastics substrate of less heat resistance other than that of glass, ceramics, etc. When an In2O3—SnO2 precursor sol is produced by hydrolyzing and polymerizing a solution containing indium alkoxide and tin alkoxide, either tri-s-butoxyindium or tri-t-butoxyindium is used as the indium alkoxide. Water is added to the solution containing indium alkoxide and tin alkoxide at a temperature of not higher than −20° C.
