    • [Purpose] An object of the present invention is to provide a composition for use in a formation of transparent and electrically conductive film having a low electric resistance and a high transmittance and a method for making the film mentioned above.[Composition] A mixture of inorganic indium compound and organic tin compound is combined with organic compound capable of coordinating with either of indium and tin to form an organic solution. When the mixture is heated, the inorganic indium compound and the organic tin compound coordinating partially with the organic compound react with water of crystallization of inorganic indium compound. The organic tin compound is partially subjected to hydrolysis to form an intermediate complex compound including indium and tin. This suppresses the evaporation of tin and generates a uniform film having a high transmittance and a low electric resistance. An addition of polyhydric alcohol increases the viscosity of the solution and gives a high stability to a resultant film obtained by applying the composition to the substrate and firing.
    • [目的]本发明的目的是提供一种用于形成具有低电阻和高透射率的透明导电膜的组合物和制备上述膜的方法。 [组成]将无机铟化合物和有机锡化合物的混合物与能够与铟和锡中的任一种配位的有机化合物组合以形成有机溶液。 当加热混合物时,与有机化合物部分配位的无机铟化合物和有机锡化合物与无机铟化合物的结晶水反应。 有机锡化合物部分进行水解以形成包括铟和锡的中间络合物。 这抑制了锡的蒸发,并产生具有高透射率和低电阻的均匀的膜。 多元醇的添加增加了溶液的粘度,并且通过将该组合物施加到基材上并进行烧制而获得的所得膜具有高的稳定性。
