Pigment Information

This color contains the following pigments:

PY17-Permanent Yellow

PY3-Hansa Yellow 10G


Pigment Name

PY17-Permanent Yellow

Pigment Type

organic, disazo

Chemical Name

Benzidine Yellow GG

Chemical Formula

Properties

Pigment Yellow 17 is a somewhat greenish yellow that has very high tinting strength and good resistance to solvents.

Permanence

Pigment Yellow 17 has good lightfastness if prepared using the proper procedures. Because procedures for preparing PY17 vary, artists may want to conduct their own lightfastness tests to verify that the manufacturer has selected quality pigment.

Toxicity

Benzidine dyes are not bioavailable. Although benzidine-based dyes can be reduced to their amine precursors in vivo, creating a compound that is carcinogenic, benzidine dyes are believed to be so insoluble in water that they are unlikely to be absorbed in

History

This Benzidine Yellow dye was first reported by Esitelty in 1949. Initiailly, it was reported to be less lightfast than yellow monoazo pigments, which limited its usefulness. A method for making Pigment Yellow 17 more permanent was patented in 1972 (United States Patent 3785843), and the improved dye became known as Permanent Yellow. Permanent Yellow 17 is widely used in printing inks, textile dyes, paints, plastics, and coatings.


Pigment Name

PY3-Hansa Yellow 10G

Pigment Type

organic, monoazo

Chemical Formula

C16H12CL2N4O2

Properties

This Hansa yellow is a transparent yellow. It has great brightness and tinting strength and its drying time ranges from average to slow. Hansa Yellow makes more intense tints and cleaner secondaries than Cadmium Yellows, especially when mixed with other organic or modern colors like Phthalo Blue and Green. Because they are more transparent, they have great value as glazing colors.

Permanence

This Hansa Yellow has fair to good permanence, particularly in the lighter 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.
