NUOVI PIGMENTI INORGANICI E PROCESSO PER PREPARARLI

摘要

The present invention relates to new inorganic pigments and to a process for preparing same. More particularly, it relates to new yellowish-green pigments consisting of titanium compounds. These pigments consist of the crystalline phases rutile TiO2, perovskite CaCO3 and trigonal CoTiO3. They contain 2 to 12% by weight of cobalt and 4 to 20% by weight of calcium based on total TiO2 and they have a dominant wave length lambda D comprised between 530 and 560 m mu .
