Phthalocyanine Green (PG7) is a synthetic, high-performance green pigment celebrated for its unparalleled intensity, transparency, and near-indestructible lightfastness. It offers a clean, versatile green that outperformed older, toxic alternatives like Emerald Green (arsenic-based) or Verdigris.
History:
In 1935, Scottish chemists at Imperial Chemical Industries (ICI) stumbled upon phthalocyanine compounds while researching industrial dyes. In 1938, PG7 hit the market as a stable, mass-produced alternative to unreliable natural greens.
