Πληροφορίες Χρωστικής

• Pigment Name
  PY1-Hansa Yellow G
• Pigment type
  organic, monoazo
• Chemical Name
  -
• Chemical Formula
  C17H16N4O4
• Properties

  This Hansa yellow is a transparent yellow. It has great brightness and tinting strength and its drying time ranges from average to slow. Hansa Yellow makes more intense tints and cleaner secondaries than Cadmium Yellows, especially when mixed with other organic or modern colors like Phthalo Blue and Green. Because they are more transparent, they have great value as glazing colors.

• Permanence

  Hansa Yellow G has good permanence and lightfastness, particularly in the lighter shades.

• Toxicity

  Hansa Yellow pigments have no significant acute hazards, though chronic hazards have not been well studied.

• History

  Hansa Yellows were first made in Germany just before World War I from a series of synthetic dyestuffs called Pigment Yellow. Hansa Yellow G, introduced in 1910, was the first of these products to be commercialized. Hansa Yellow G was the standard yellow for printing inks until late in the 20th century, when stronger diarylide yellows began to replace it. It is still used a great deal in packaging, and for air drying paints.

• Properties

  Pigment PR4 is an opaque, bright yellowish red pigment with high tinting strength.

• Permanence

  Pigment PR4 has good lightfastness, but newer red pigments are considered more permanent and reliable.

• Toxicity

  Known also as D&C Red No 36, PR4 is used in cosmetic products such as lipsticks. It has been tested for carcinogenic and mutagenic effects in laboratory rats.

• History

  Because it is inexpensive and has a long history of use in cosmetic products, Permanent Red PR4 is widely used in artist materials where safety is more important than archival preservation, as in children's art materials.
