Concern of people on safety of chemical products and preservation of the environment has been increasing for past several years. Paint industry is also required to cope with the problems on VOCs and toxic substances and so on which are generated from paints. This report focuses trend of development of protective coatings which contain no toxic heavy metals, with special emphasis on anticorrosive pigments. Anticorrosive pigments were classified into several types according to their functions, and current studies were introduced for each type. Synergism of different types of pigments, ion exchanging pigments, and chelate type pigments will be some of the alternatives, further, coatings free of anticorrosive pigments may be attained by use of chelate-modified polymers.
