For the coloring of paints, inks, plastics and rubber, etc. There are 160 kinds of commercial dosage forms of the pigment. Compared with CuPc of other crystal forms, the unstable α-crystal form CuPc gives stronger red light, has higher tinting strength and low cost. It is mainly used for offset printing ink packaging and metal decorative printing ink. Under normal conditions, it is stable to organic solvents. When stored in aromatic hydrocarbons, the crystal form and shade change; when plastic is colored, it is resistant to migration and has excellent light fastness. Under 200 ℃, it can be converted into β-type by further increasing the temperature; it is also suitable for polyurethane foam and rubber; the pure and bright shade makes it suitable for water-based paint and paper coloring and paint printing color paste.
