About this product range

Amsterdam Acrylics have the viscosity, pigmentation level, and lightfastness that professionals demand. The well-balanced range of 70 genuine artists' colors is formulated with high concentrations of authentic, non-fading pigments, which guarantees strong and intense colors. 28 colors in the line are mono-pigmented . This heavy-body paint is suitable for working with a brush or painting knife. Paints are formulated with 100% acrylic resin binder, which results in an exceptionally durable and flexible paint film with a uniform degree of gloss. Thin films dry in 30 minutes. Expert Acrylics thin easily with water and are virtually odorless. Being alkali resistant makes them ideal for wall paintings. They exhibit the highest degree of lightfastness so colors remain brilliant and true for years. Paints are packaged in clear, recylable tubes.

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.

Phthalo Blue

Pigment code
PB15
Type
organic
Chemical name
copper phthalocyanine
Chemical formula
C32H16CuN8
Properties
Phthalo Blues are pure and clean primary blues with superior covering power. They have a very high tinting strength and tend to overwhelm other pigments, but if color strength can be controlled, they make predictable mixed colors. In oil form, blues are very deep and slow drying. When mixed with other colors or if chlorine is added, Phthalo Blue quickly tends towards green. When using alone, mix with some white, as Phthalo Blue can be semi-transparent and almost black on its own. It is among the most compatible of modern colors with mineral colors and is considered more reliable than Prussian Blue, while sharing the same physical and color properties. Phthalo Blue is a good color for glazing.
Permanence
Phthalo Blues are completely lightfast and stable and are permanent for all paint uses. They are currently used in inks, coatings, and many plastics due to their stability and are considered a standard pigment in printing ink and the packaging industry.
Toxicity
Phthalo Blues have no significant hazards, although those made before 1982 contained some PCBs (polychlorinated biphenyls).
History
Developed by chemists using the trade name Monastral Blue, the organic blue dyestuff now known as Phthalo Blue was presented as a pigment in November 1935 in London. Its discovery was accidental. The dark color was observed in a kettle where a dye was being made from a British dyestuff plant. The demand for such a pigment came from commercial printers who wanted a cyan to replace Prussian Blue.
