About this product range

M. Graham puts the same care and attention to detail into acrylic paints that he lavishes on more traditional media. Each color is manufactured only in small batches, using a traditional three roller mill.

Only pure, high solid resins are used, with no fillers, retarders, opacifiers, or bulking agents. Each pigment is present in the highest concentration possible consistent with good working properties. This gives each color outstanding tinting strength and mass tone.

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.
