Πληροφορίες Χρωστικής

• Pigment Name
  PG7-Phthalo Green
• Pigment type
  organic
• Chemical Name
  polychlorinated copper(II) phthalocyanine
• Chemical Formula
  C32H3Cl13CuN8 to C32HCl15CuN8 or C32H16CuN8Cl15 (PG7) or C32Br6Cl10CuN8 (PG36)
• Properties

  Phthalo Green is a transparent, cool, bright, high intensity color used in oil and acrylics. It comes from a Phthalocyanine Blue pigment where most of the hydrogen atoms have been replaced with chlorine, forming highly stable molecules. It has similar pigment properties and permanence to Phthalo Blue. It is slow drying and an excellent base color for mixing a range of bright greens. Phthalo Green is considered a very good alternative to Viridian because it is intense and mixes well and can be used to emphasize mineral colors in various tints. However, its tinting strength is very high, so it can overpower other colors. This pigment most closely resembles the discontinued and toxic Verdigris.

• Permanence

  Phthalo Greens are completely lightfast and resistant to alkali, acids, solvents, heat, and ultraviolet radiation. 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 Green has no significant hazards, but it contained PCBs (polychlorinated biphenyls) until 1982.

• History

  This bright blue-green was developed in 1935 and has been in use since 1938.

• Pigment Name
  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.

• Pigment Name
  PG17-Chromium Oxide Green
• Pigment type
  inorganic
• Chemical Name
  chromium oxide
• Chemical Formula
  Cr2O3
• Properties

  Chromium Oxide Green is a dull, dense, willow or pale green color that is completely opaque. It has an average drying time and a low tinting strength. It is fairly flexible in oil form and is suitable for all purposes and mediums. This pigment is less versatile in mixtures than Viridian and Phthalocyanine Green, but mixes well with other colors without overpowering them.

• Permanence

  Chromium Oxide Green has excellent permanence, even at high temperatures.

• Toxicity

  Chromium Oxide Green is slightly toxic. Evidence of Chromium(III) carcinogenicity is inconclusive. Chromium(III) salts appear in greenish pigments such as PG17. Chromium(VI) salts, which appear in yellowish pigments, have been proven to cause cancer.

• History

  Louis-Nicolas Vauquelin discovered the element chromium in lead chromate in 1797. It began to be used as an enamel and ceramic color in 1809, but it had limited use as a pigment until 1862, because of its cost. It is the most commonly used green for military camouflage because it appears the same shade as living foliage under infrared light.
