Hansa Yellow-Monoazo Yellow: Like diarylide yellow this group also has several pigments, but only few important pigments are listed here. Pigments in this group are commonly used in aqueous paint industry.
Some pros:

• excellent alkali resistance
• inorganic lead free replacement & no darkening
• offers high tint strength and brighter chroma

Some cons:

• low opacity – to mask low opacity higher amounts TiO₂ required
• low exterior durability

Benzimidazolone Yellow: This pigment is relatively new, but very popular for plastic, PVC, and coating applications because of its excellent light fastness and heat, solvent & chemical resistance in masstone.

Disazo Yellow: This pigment offers excellent light fastness, heat, solvent & chemical resistance in masstone with wide range of end applications such as textile printing, ink, plastic and coatings.

Isoindolinone Yellow: This pigment is mainly used for high performance plastic, automotive paints and man made fiber.
