Abstract: A solution composition comprising a conductive polymer, a resin, and a solvent is described. The solution composition has an acid value of 0.0 to 14.5 mgKOH/g or a base value of 0.0 to 1.0 mgHCl/g. The solution composition may be applied to a surface such as a steel surface and dried to obtain a film. The obtained film may be used for rust inhibition.
