摘要：
An anticorrosive pigment composition containing neither any heavy metal harmful to the environment nor zinc, which may be harmful to the environment. The composition is a product of the reaction of (a) aluminum dihydrogen tripolyphosphate, (b) a calcium compound selected among oxides, hydroxides, and carbonates, and (c) a magnesium compound selected among oxides, hydroxides, and carbonates. The composition exerts no adverse influence on the storage stability of water-based anticorrosive coating materials.
