Pigment Name

PR188 -Naphthol Red

Pigment Type

organic monoazo

Chemical Formula

C33H24Cl2N2O6

Properties

This Naphthol Red is yellowish, with a high tinting strength and average drying time. It produces warmer shades and tints.

Permanence

This Naphthol Red has excellent lightfastness, though it is generally not considered adequate 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 Name

PW6-Titanium White

Pigment Type

inorganic

Chemical Name

titanium dioxide

Chemical Formula

TiO2

Properties

Titanium White is the most brilliant of the white pigments. It is considered an all purpose oil color useful in all techniques and the best all around white. Its masstone is neither warm nor cool, placing it somewhere between Lead White and Zinc White. It is less prone to cracking and yellowing than Lead White, but it still yellows easily. Titanium White dries slowly in oil form, more slowly than Lead White but more quickly than Zinc White. It is opaque in oil and acrylic forms and semi-opaque in watercolor form. This pigment has good chemical stability, and its tinting strength is superior to both Lead White and Zinc White.

Permanence

Titanium White has excellent permanence and lightfastness.

Toxicity

Titanium dioxide is highly stable and is regarded as completely non-toxic. Animal studies give no indiciation that it is absorbed biologically, even after long periods of exposure. The primary safety concern is with inhalation of fine pigment dust particl

History

Titanium is the ninth most abundant element in the Earth's crust, however mineral deposits that are economical to mine are less common. Titanium dioxide was first discovered in 1821, although it could not be mass produced until 1919. Widespread use of the pigment began in the 1940s. Since that time, it has become the most commonly used white pigment. The name comes from the Latin word Titan, the name for the elder brother of Kronos and ancestor of the Titans, and from the Greek word tito, meaning day or sun.


Pigment Name

PY97-Permanent Yellow

Pigment Type

organic, monoazo

Chemical Formula

C26H27ClN4O8

Properties

Permanent Yellow PY97 ranges from reddish yellow to greenish yellow with temperature shifts from cool to warm hues. It has good tinting strength and average to slow drying time. Similar in shade to Hansa Yellow 1, it offers much better fastness properties and good heat stability.

Permanence

Pigment PY97 has excellent lightfastness, particularly in the darker shades.

Toxicity

No significant acute hazards of PY97 are known, though 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. Permanent Yellow (PY97) represents a further development of this line, with the aim of producing a yellow pigment that is suitable for exterior use.
