Liquitex Professional Heavy Body Acrylics are high-viscosity acrylics formulated for bold color and precision handling. Formerly known as High Viscosity, this line features a thick consistency that retains crisp brushstrokes and knife marks—ideal for impasto, layering, and textural work.

High pigment loads deliver rich, permanent color with excellent lightfastness, while a low-odor acrylic resin base offers increased open time and a smooth working experience with minimal wet-to-dry color shift. The paint’s strong surface drag allows for controlled blending and expressive mark-making using brushes or knives. It’s equally suited to traditional painting, mixed media, collage, and printmaking techniques.

When dry, paint films remain flexible, non-yellowing, water-resistant, UV resistant, and pH neutral. Available in a range of versatile sets, Liquitex Heavy Body Acrylics are a great choice for both beginners exploring acrylics and experienced artists seeking professional-quality results.

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.
