About this product range

Paint fast or paint slow with Chroma Atelier Interactive Acrylics!

Formulated using a patented technology, Atelier Interactive Acrylics offer artists a versatile set of working properties unlike those of any other paint. In application, they perform like conventional acrylics, allowing for traditional painting and glazing techniques. Yet they also give you unique control over the drying process — plus the ability to reactivate the paint, even when dry.

Professional-quality Atelier Interactive Acrylics are lightfast and archival, with exceptional consistency, brushability, and color load. They dry to a velvety satin finish. When purchased in 80 ml tubes, they offer one-third more paint than standard 60 ml tubes — and often costs less.

Pigment information

General reference notes about pigments can describe other media (such as oil). They do not verify this product’s exact formulation or behavior.

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.

History
The benzimidazolone group of pigments was developed and patented in 1960 by Hoechst A.G., a German chemical manufacturer that was a forerunner of the pharmaceutical company Aventis.
