Description

Diarylide Yellow is a high-performance red-shade yellow azo pigment, that is more opaque, has good tinting strength, and enhanced outdoor durability. Diarylide Yellow (PY83) pigments offer better solvent and migration resistance than monoazo yellow pigments making them a good pigment for inks, plastics, and paint. Our Diarylide yellow is a reddish-yellow pigment recommended for paints as an alternative to replace reddish shade chrome yellows to produce lead-free paints as well as for inks.

Origin and History

The first azo pigment, tartrazine yellow, PY100, which is still used in artists’ paints, was patented in 1884. β-naphthol azo pigments were first introduced from 1895 to 1911, and they are still in production. The first Hansa yellow, PY1, was patented in 1909, and the first diarylide was synthesized in 1911. Because their importation from Germany was forbidden during World War I, American manufacturers began to study azo dyes in depth. Azo pigments have become the largest class of synthetic organic pigments because of their ease of preparation and wide range of colors. Diarylide yellow pigments are made in a color range from greenish- to reddish-yellow shades.

Diarylides were not widely used until almost twenty-five years after their synthesis in 1911. At that time, they were sold as pigments for rubber under the trade names Vulcan Fast Yellows and Oranges. Diarylides are an important class of azo pigments and now account for approximately 80 percent of all yellow pigments. They are primarily used in printing inks, where twenty-five thousand metric tons were used in 1989.

Diarylide Yellow, PY83, also known as Permanent Yellow HR, is more non-bleeding and lightfast than other diarylide yellows. It was introduced in 1958 by Hoechst and is a reddish yellow pigment used in plastics, printing, and artists’ colors.

Source

Diarylides are synthetic organic pigments formed by the coupling of tetraazotized benzidines with acetoacetarylides. They are disazo compounds with a backbone structure based on 3,3'-dichlorobenzidine.

Permanence and Compatibility

Diarylides have approximately twice the tinting strength of monoarylides and show improved bleed resistance and thermal stability due to their higher molecular weight.

Oil Absorption and Grinding

Diarylide yellow absorbs a large amount of oil—for every 100 grams of diarylide yellow 58 grams of linseed oil is needed to form a coherent paste, and is the oil absorption value for this pigment.

Toxicity

Diarylide yellow is not considered toxic, however, care should be used in handling the dry powder pigment to avoid inhaling the dust. All toxicological studies showed no signs of toxicity to humans or the environment.

Ecology

Diarylide yellow is among organic pigments that contain inadvertent polychlorinated biphenyls (PCB) or dichlorobenzidine (DCB) compounds.
