Abstract

1. Painting composition or paste containing a phosphate based, corrosion-inhibiting pigment for protecting iron and iron alloy surfaces characterized in that the corrosion-inhibiting pigment consists to an extent of 5 to 35 weight % of MgHPO4 .3 H2 O, the balance being CaHPO4 .2 H2 O, and the corrosion-inhibiting pigment is present in the dried protective coating in a pigment volume concentration of 10 to 60, preferably 20 to 40, volume %.
