Color Swatch created using heavy to light application and was applied on 100 lb (163 gsm) drawing paper material.
This color contains the following pigments:
PO61—Isoindoline Orange 61
Pigment Type
organic, azomethine
Chemical Name
isoindoline orange
Chemical Formula
n/a
Properties
Isoindoline Orange 61 is an opaque, yellowish orange pigment with moderate tinting strength.
Permanence
Isoindoline Orange 61 has very good lightfastness, although not as good as yellow pigments in the isoindoline group.
Toxicity
Isoindoline Orange 61 is not considered toxic.
History
The first isoindoline pigments were patented in 1946, and commercial production of pigments in this group began in the 1960s. Because of its high heat stability and relatively good lightfastness, PO61 is used in plastics, automotive finishes, and for printing inks. PO61 is often compared with PO13, which has higher tinting strength, but is not as lightfast.
Alternate Names
Permanent Orange.
PO43—Perinone Orange
Pigment Type
vat, anthraquinone
Chemical Name
n/a
Chemical Formula
C26H12N4O2
Properties
Perinone Orange is a strong, clean, reddish orange pigment classified as a vat pigment. It has an average drying time.
Permanence
Perinone Orange has excellent lightfastness and weatherfastness.
Toxicity
Perinone Orange is not considered toxic.
History
Perinone orange is often used in plastics and vinyls, automotive finishes, and printing inks. Its high cost limits its application to products for which superior lightfastness and weather resistance is essential. In textiles, it is used in synthetic fabrics that must survive in harsh conditions, such as tents and awnings.
Alternate Names
Perionone Orange.
PBk11—Mars Black
Pigment Type
earth
Chemical Name
iron oxides
Chemical Formula
FeO or Fe2O3
Properties
Mars Black is an opaque black with a strong and cool masstone, a slightly warm tint, and a warm brown undertone. It is not as black as Ivory Black, but it dries more quickly and has three times the tinting strength. Mars Black is normally the only black available in acrylic form and that is safe to over paint. It can be used in all media without reservation and is widely used as an alternative to Lamp Black and Ivory Black.
Permanence
Mars Black is very lightfast with excellent permanence.
Toxicity
Mars Black has no significant hazards and is the only major black pigment considered non-toxic.
History
The word Mars refers to the Roman god of iron and war. Mars Black was developed in the early 20th century from inorganic, synthetic iron oxide.
Alternate Names
Black Iron Oxide, Iron Black, Magnetic Oxide, Mapico Black, Mineral Black. Sometimes labeled as Vine Black.
