What is phthalocyanine blue crude?
Phthalocyanine Blue BN, also called copper phthalocyanine (CuPc) and many other names, is a bright, crystalline, synthetic blue pigment from the group of phthalocyanine dyes. Its brilliant blue is frequently used in paints and dyes.
Is phthalocyanine blue the same as Phthalo blue?
Winsor Blue is made of an organic synthetic pigment, copper phthalocyanine. Alternative names are phthalo blue, monastral and intense blue.
How is phthalocyanine blue made?
Phthalocyanine blue is prepared by heating a mixture of phthalic anhydride, urea, and copper chloride. It then becomes copper-phthalocyanine but is not conditioned as a pigment until it is dissolved in concentrated sulfuric acid and carefully washed in excess water and filtered.
What is phthalocyanine dye?
Phthalocyanine is an intensely blue-green-colored aromatic macrocyclic compound that is widely used in dyeing and the first phthalocyanine (Pc) was synthesized accidentally in 1907 as an unidentified blue compound when o-cyanobenzamide was heated at high temperature and that substance is currently known to be the metal …
How do you mix phthalocyanine blue?
There is no exact color combination that is able to make phthalo blue due to it being a synthetically created, high chroma color. That said, you can mix colors with either french ultramarine blue or cerulean blue hue and get a very similar look with minimal effort or expense required on your part.

What is Phthalogen Dye IBN (GK 161)?
The dye derived from cobalt phthalocyanine and an amine is Phthalogen Dye IBN. 1,3-Diiminoisoindolene, the intermediate formed during phthalocyanine manufacture, used in combination with a copper salt affords the dye GK 161. Phthalocyanine Blue BN is also used as a source material for manufacture of Phthalocyanine Green G .
What is Sulfonated phthalocyanine and why is it dangerous?
