Pigment Name

PY74-Hansa Yellow

Pigment Type

monoazo

Chemical Formula

C18H18N4O6

Properties

Pigment PY74 is one of the most commercially important pigments of the Hansa Yellow group, considered superior to many others in its class based on both tinting strength and lightfastness. Several PY74 grades with different particle sizes are available. Grades with finer particle size are more brilliant and transparent. Pigment PY74 ranges from reddish yellow to greenish yellow, with temperature shifts from cool to warm hues. It has high tinting strength and average to slow drying time.

Permanence

This Hansa Yellow has better lightfastness that other yellow monoazo pigments, particularly in the darker shades.

Toxicity

Hansa Yellow has no significant acute hazards, though its chronic hazards have not been well studied.

History

Hansa Yellows were first made in Germany just before WW1 from a series of synthetic dyestuffs called Pigment Yellow. They were intended to be a synthetic replacement for Cadmium Yellow.


Pigment Name

PY95-Disazo Condensation Yellow

Pigment Type

organic, disazo condensation

Chemical Formula

Properties

Pigment PY95 is a semi-transparent reddish yellow pigment with high tinting strength, slightly less reddish in hue than the popular PY83.

Permanence

For a yellow organic pigment, Disazo Condensation Yellow 95 has very good lightfastness, although its lightfastness is not as good as that of red disazo condensation pigments.

Toxicity

Disazo Condensation Yellow has no significant acute hazards. Chronic hazards have not been well studied.

History

Disazo Condensation Yellow PY95 is sometimes used in yellow inkjet printer inks and other high-grade, special purpose inks.
