Abstract

A conductive metal oxide based layer on a substrate is prepared by chemically reducing a metal salt in aqueous solution, coating the resulting aqueous metal dispersion after washing onto a substrate, preferably glass, and subjecting the coated layer to an oxidizing treatment, e.g. a heat step. In a preferred embodiment the metal oxide is tin oxide, or a mixture of tin oxide and another metal oxide.
