Abstract
An indium tin oxide sol composition comprising about 0.5 to about 30% by weight of indium oxide, tin oxide in an amount of about 0.5 to about 30% by weight, as converted to a basis of tin, based on indium in the indium oxide, and a dispersing agent, which sol composition is obtained by contacting a solution of an indium salt of an inorganic acid containing a tin salt of an inorganic acid with an ion-exchange resin is disclosed. The indium tin oxide sol composition has a high purity and forms an excellent transparent conductive film.
