摘要

1398215 Composite green pigment CHEMETRON CORP 14 June 1973 [14 June 1972] 28355/73 Heading C4A [Also in Division C3] A composite green pigment comprises 56- 82% by wt. of one of the organic yellow pigments Pigment Yellow 3 or Pigment Yellow 4, 2-41% beta copper phthalocyanine, and 2- 30% Ferrite Yellow, the spectral reflectance curve of the pigment having one major inflection in the wavelength range 460-700 nanometers. The pigment has a low oil absorption value and can be used as a substitute for chrome green in paints and lacquers.
