Abstract: The present invention relates to a corrosion-protective composition containing a wax, an unsubstituted or substituted polyaniline in a doped form and a liquid paraffin, and articles comprising the composition applied on a substrate. It also relates to a process for manufacturing the composition, wherein i) a first dispersion of a polyaniline in a doped form is prepared; and ii) the first dispersion of the polyaniline is combined with a wax component to sufficiently disperse the polyaniline therein, and to the use of the composition as a single layer coating for the protection against corrosion of a substrate in need thereof.
