Color Swatch created using heavy application/medium application/50% tint and was applied on acrylic primed canvas (7 oz) material.
This color contains the following pigments:
PY3—Hansa Yellow 10G
Pigment Type
organic, monoazo
Chemical Name
n/a
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.
Alternate Names
Arylamide Yellow, Arylide, Arylide Yellow, Azo, Brilliant Yellow, Monoazo, Monolite Yellow, Permanent Yellow.
PY65—Hansa Yellow
Pigment Type
monoazo
Chemical Name
n/a
Chemical Formula
C18H18N4O6
Properties
This Hansa Yellow 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.
Permanence
This Hansa Yellow has excellent lightfastness, 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.
Alternate Names
Arylide, Arylide Yellow, Azo, Brilliant Yellow, Monoazo, Monolite Yellow, Permanent Yellow.
PR112—Naphthol Red AS-D
Pigment Type
organic, monoazo
Chemical Name
n/a
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.
Alternate Names
Naphthal, Naphthol Bordeaux, Naphthol Carbamide, Naphthol Carmine, Permanent Carmine, Permanent Red, Fanchon Red.
PW6:1—Buff Titanium
Pigment Type
inorganic
Chemical Name
titanium dioxide
Chemical Formula
TiO2
Properties
Buff Titanium is an warm, reddish, off-white pigment that shares the properties of Titanium White, including opacity and slow drying time.
Permanence
Buff Titanium is lightfast and permanant.
Toxicity
Titanium dioxide and iron oxide are naturally occuring and are abundant in the Earth's crust. Both are considered non-toxic. Particle sizes tend to be larger in Unbleached Titanium than for titanium dioxide pigments used in white paints.
History
Titanium dioxide often occurs in nature with iron oxide. Buff or unbleached titanium is a natural mineral form of titanium dioxide. A variety of processes are used to produce buff or unbleached titanium. Some manufacturers may add synthetic iron oxides to a titanium base, while others use naturally occuring titanium ores that contain impurities. In this respect, Buff Titanium or Unbleached Titanium is a color that that may vary from one manufacturer to another.
Alternate Names
Off-White, Unbleached Titanium.
