Arylide yellow, also known as Hansa yellow and monoazo yellow, are a family of organic compounds used as pigments. They are primarily used as industrial colorants including plastics, building paints and inks. They are also used in artistic oil paints, acrylics and watercolors. These pigments are usually semi-transparent yellows and yellow-greens. Related organic pigments are the diarylide pigments. Overall, these pigments have partially displaced the toxic cadmium yellow in the marketplace. Painters such as Alexander Calder and Jackson Pollock are known to have employed arylide yellow in their artworks.
Members of this class include:
- Pigment Yellow 6 (CAS# 2512-29-0), derived from 4-chloro-2-nitroaniline (diazonium precursor) and aniline (acetoacetanilide precursor) to produce medium yellows.
- Pigment Yellow 3 (CAS# 6486-23-3), derived from 4-chloro-2-nitroaniline (diazonium precursor) and 2-chloroaniline (acetoacetanilide precursor) to produce greenish-yellows.
- Pigment Yellow 16 derived from 2,4-dichloroaniline (diazonium precursor) and tolidine (acetoacetanilide precursor) to produce medium-yellows.
- Pigment Yellow 74 (CAS# 6358-31-2), derived from 2-methoxy-4-nitroaniline (diazonium precursor) and 2-methoxyaniline (acetoacetanilide precursor) to produce greenish-yellows.
