Plastics quinacridone pigments

Quinacridone pigments are available in orange, red, and violet. They have good light fastness, excellent bleed and chemical resistance, and adequate heat stability for most plastics. However, they are high in cost. They perform best in polystyrene and acrylic at lower temperatures. They are not recommended for nylon. [Pg.385]

Quinacridone is the trivial name given to the five-ring heterocyclic system exemplified by the linear irani-quinacridone (2.69). The yellow-red to reddish-violet shade pigments based on this ring system show outstanding durability and are used in plastics, in industrial and automotive finishes and in exterior finishes. Like copper phthalocyanines the unsubstituted linear quinacridone exhibits polymorphism and two crystal forms, the reddish violet P-form and the red y-form, are commercially... [Pg.120]
