A corrosion inhibiting coating for metallic substrates, the corrosion inhibiting coating has an anticorrosive hydrophilic layer that includes at least a corrosion-inhibiting agent dispersed therein; and an impervious layer to oxygen and moisture over the hydrophilic layer. The anticorrosive hydrophilic layer is comprised of one or more water-soluble polymers such as, for example, polyvinyl pyrrolidone; one or more corrosion-inhibiting agents, such as, for example, salt of zinc and preferably zinc citrate; one or more cross-linking agents such as, for example, butanediol; and one or more solvents, such as, for example, water. Likewise, an article having anticorrosive function is provided, said article is comprised of a metallic substrate; an anticorrosive hydrophilic layer on the metallic substrate, such that the anticorrosive hydrophilic layer includes at least a corrosion-inhibiting agent dispersed therein; and an impervious layer to oxygen and moisture over said anticorrosive hydrophilic layer.
