Pigment Information
This color contains the following pigments:
PR170-Naphthol Red
PY74-Hansa Yellow
PO16-Dianisidine Orange
Pigment Name
PR170-Naphthol Red
Pigment Type
organic, naphthol AS
Chemical Formula
C26H22N4O4
Properties
Pigment PR170 is a bright deep red with bluish undertones. It has an average drying time. It has two crystaline forms that differ significantly in opacity. The more transparent form (F5RK) tends to be more bluish and is less lightfast.
Permanence
The lightfastness and weatherfastness of Pigment PR170 varies, depending on the application and the crystaline form. The opaque form (F3RK) has very good lightfastness, and is more weather resistant. The transparent form (F5RK) has lightfastness that is considered acceptable in pure applications, but it fades more in tints. Neither form is considered suitable for exterior use.
Toxicity
Naphthol Reds are not considered toxic. They may cause eye, skin, or respiratory irritation. Contact with dry pigment should be avoided.
History
Naphthol pigments are actually dyes that are "laked" to form pigments. First developed by the German chemical company Hoechst A.G. before World War I, their use in artist paints began in the 1920s. Pigment Red PR170 is a Naphthol AS pigment, chemically related to the diarylide yellow pigments. The Naphthol AS pigments comprise a range of reds. They are used in plastics, textiles, and printing inks.
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
PO16-Dianisidine Orange
Pigment Type
organic, disazo
Chemical Formula
C34H32N6O6
Properties
Dianisidine Orange is a semi-opaque orange dye that can be laked to form a pigment. This pigment ranges from yellowish to reddish orange in different laked forms.
Permanence
Dianisidine Orange has only fair lightfastness.
Toxicity
A Japanese study in which rats were given large daily doses of Dianisidine Orange revealed no acute toxicity or mutagenic effects.
History
Dianisidine Orange is used mostly in coloring plastics and in inks, in applications where safety is important but lightfastness and longevity are not paramount.
