A two-component curable paint composition comprises a base component containing at least one curable resin, and a hardening component which contains a non-conducting polyaniline, and a liquid-phase or molten-phase curing agent capable of curing said curable resin of the resin component and capable of dissolving non-conducting polyaniline. According to the invention, the curing agent comprises an organic amine compound having at least two primary amine functions linked together by a hydrocarbon chain which is optionally interrupted by at least one heteroatom, said amine compound exhibiting irregularities in the chemical structure of its hydrocarbon chain. The invention also provides a method of preparing paint compositions, a method of forming a paint coating on the surface as well as a coated metal surface. The solutions produced by the invention are stable over extended periods of time, and the anti-corrosive erect of the paint compositions is good even at very low concentrations of the polyaniline.
