The present invention deals with corrosion inhibitor-Preparations and anti-corrosion paint or corrosion protective primer coats. An anti-corrosive colors, the anion exchanging polymers in the form of weakly basic anions and in nitrite-form, as well as an alkaline earth metal and contain alkali metal phosphate, an effective corrosion protection guarantee by passivation of ferrous alloys. Polymers with imidazolium groups or phosphonium groups are preferred. According to a preferred embodiment, a corrosion protecting preparatioy or. Color further alkaline earth phosphate particles, so as to create a system for slow release of anti-corrosive ions is maintained even in weak ionized water, so that the metal to be protected in a passive state and in a constantly to optimum alkaline pH-interval.
