Disazo dye

Description

A class of synthetic organic pigments formed by two coupled arylide molecules followed by precipitation to obtain an insoluble pigment. Disazo dyes are more commonly called Diarylide dyes or pigments. They were first developed in Europe in the mid 1950s and were introduced in the U.S. in 1960. Their colors range includes yellow, orange, brown, red and violet. Disazo colors, in general, have low solubility in organic solvents and fair to good lightfastness. They are used for printing inks, plastics, and paints.
