RUST-PREVENTIVE PIGMENT COMPOSITION AND RUST-PREVENTIVE PAINTS CONTAINING THE SAME

摘要

The present invention relates to an anti-corrosive pigment composition, characterized by comprising, as main components, white anti-corrosive pigment and an inorganic anion exchanger represented by the following formula (1):        (3-4)[M₁]O·Al₂O₃·[M₂]X_2/m·nH₂O     (1)   (wherein, M₁ and M₂ are at least one selected from Ca²⁺ or Zn²⁺, X represents at least one anion selected from NO₂^-, NO₃^-or MoO₄^2-, m represents a valency of the anion, and n is 20 or less).
