Abstract
A metal treating composition comprising at least a specific type of dissolved and/or dispersed organic resin, a dissolved vanadium compound in which the valence of vanadium is from 3 to 5, and a dissolved compound that contains at least one of the metals Zr, Ti, Mo, W, Mn, and Ce can provide metal surfaces with superior corrosion resistance, alkali resistance, and fingerprint resistance. The composition contains no chromium to cause pollution problems and/or require pollution abatement.
