PR254-Pyrrole Red

PW4-Zinc White

PY184-Bismuth Yellow


Pigment Name

PO73-Transparent Pyrrole Orange

Pigment Type

organic, aminoketone

Chemical Name

dipyrrolopyrrol

Chemical Formula

Properties

Transparent Pyrrole Orange is a yellow-shade orange with optimum performance; high saturation and excellent durability, excellent bleed resistance, and intrinsic strength coupled with good opacity and moderate rheology. It is semi-opaque, less opaque than Cadmium Orange.

Permanence

Transparent Pyrrole Orange has been demonstrated to have excellent stability and lightfastness in automotive applications.

Toxicity

The Australian government's Department of Health and Aging, reported in its Summary Report: NA/238 that "Irgazin DPP Orange 16AOA is likely to be of low oral and dermal toxicity in humans and to be non irritating or very slightly irritating to the ey

History

Irgazin Orange was developed as a lead-free alternative opaque orange pigment. It is used in decorative, industrial, and automotive applications, often to color plastics and polymers.


Pigment Name

PR112-Naphthol Red AS-D

Pigment Type

organic, monoazo

Chemical Formula

C24H16Cl3N3O2

Properties

This Naphthol Red is an intense scarlet red pigment that is heavily staining. It has an average drying time. It is semi-transparent and has relatively poor covering power.

Permanence

This Naphthol Red has been rated as having excellent lightfastness under ASTM testing, but other testing methods have demonstrated some tendancy for the color to fade with exposure to strong ultraviolet light. It has been considered a replacement for less lightfast naphthol reds such as PR3. Not suitable for exterior use.

Toxicity

Naphthol Reds are not considered toxic. Naphthol Red AS-D may cause eye, skin, or respiratory irritation. Contact with dry pigment should be avoided.

History

Unknown.


Pigment Name

PR254-Pyrrole Red

Pigment Type

organic, aminoketone

Chemical Name

Bis-(p-chrolopheny)-1. 4-diketopyrrolo(3. 4-c)pyrrole

Chemical Formula

Properties

Pyrrole Red is opaque and has strong covering power. According to manufacturer Ciba, which uses the trade name Irgazin Red, it is a “clean, highly saturated mid shade red with high temperature resistance, excellent color strength, outstanding chemical, solvent and bleed resistance, and good weatherfastness.”

Permanence

Pyrrole Red is considered to have excellent lightfastness among organic pigments in its class. Tests in industrial applications have given it scores of 7-8 on the Blue Wool Scale.

Toxicity

According to the Australian government's Ministry on Health and Aging, "The notified chemical exhibited low oral and dermal toxicity in rats, did not exhibit toxic effects when administered orally to rats for 28 days, was not a skin irritant in rabbi

History

Pyrrole Red, used as an automotive paint and as a colorant in plastics, was developed as one of a range of pigments to replace lead based pigments. In art materials, it is often used as a synthetic and lightfast replacement for carmine, a laked pigment that was originally produced from the body of the cochineal insect. It is also used to replace the older naphthol reds, organic red pigments that are sometimes only marginally lightfast and weatherfast.


Pigment Name

PW4-Zinc White

Pigment Type

inorganic

Chemical Name

zinc(II)-oxide

Chemical Formula

ZnO

Properties

Zinc White is the coolest white, and it has a cold, clean masstone and a slightly bluish tint. It has less hiding power and is more transparent than other whites. It dries slowly and is good for painting wet into wet and for glazing and scumbling. Zinc White is neither as opaque nor as heavy as Lead White, its covering power is not as good, and it takes much longer to dry. However, it does not blacken when exposed to sulfur in the air as Lead White does. It is very valuable for making tints with other colors. Unmixed Zinc White dries to a brittle and dry paint film that may crack over the years, so it is not good for frescoing. It is more transparent in acrylic form than Titanium White and is the most commonly used white with gouache. Chinese White is a version of Zinc White appropriate for opaque watercolor techniques.

Permanence

Zinc White has great permanence and lightfastness.

Toxicity

Zinc White is moderately toxic if ingested and slightly toxic if inhaled.

History

Though historians are divided on who first isolated the element zinc, they agree that it was first suggested as a white pigment in 1782. Zinc White was accepted as a watercolor in 1834 and was called Chinese White due to the popularity of oriental porcelain in Europe at the time. Ten years later, a suitable oil form was produced. By the early 20th century, it had improved to the point where it was an acceptable alternative to Flake White.


Pigment Name

PY184-Bismuth Yellow

Pigment Type

inorganic

Chemical Name

bismuth orthovanadate or bismuth vanadium oxide

Chemical Formula

BiVO4

Properties

Bismuth Yellow is an intense, light value, semi-opaque yellow pigment with good tinting strength.

Permanence

Bismuth Yellow has excellent lightfastness.

Toxicity

Bismuth orthovanadate is harmful if swallowed. It is irritating to the eyes, respiratory system, and skin. Exposure may cause conjunctivitis, rhinitis, and reversible irritation of the respiratory tract. More severe cases may cause bronchitis, bronchospas

History

Bismuth orthovanadate occurs naturally in several minerals. Although it was synthesized in the 1920s, it was not developed as a commercial pigment until the 1970s.
