Abstract

Pigments of formula: (where X is arylene, and the ring Y may also be substd.) are made by condensing 1 mole of a diamine X-(NH2) and 2 mole of an opt. substd. 2-hydroxy-3-carboxy-naphth-1-aldehyde, including a treatment in the final stage of prepn. in a neutral or acidic aqs. medium at 50-115 degrees C, opt in the presence of a surfactant and a water soluble, organic solvent removable by steam distillation. They are used as pigments for plastics e.g. PVC and have excellent resistance to solvents and migration.
