Phthalocyanine Green

PG 7 Phthalocyanine Green: The controlled chlorination of phthalocyanine blue pigment yields very yellow to deep blue shade, which yields phthalocyanine green.  The maximum chlorination produces very yellow shade and as the chlorination is reduced the variety of yellow shade to blue shades are produced.   Inexpensive blue shade phthalocyanine greens can be produced by physically blending very small amounts of phthalocyanine blue with a very yellow shade phthalocyanine green but the cleanest blue shade green can be produced by controlled chlorination only.   This pigment group of pigment offers excellent light fastness & chemical resistance in masstone and tint.

PG 36 Phthalocyanine Green: Very clean shade yellow phthalocyanine green is produced by chlorination and bromination of phthalocyanine blue pigment.   Maximum bromination will produce a very yellow phthalocyanine green. This pigment group of pigment offers excellent light fastness & chemical resistance in masstone and tint.
