All pigments undergo input control for the main parameters in the company's laboratory using modern equipment. Phthalocyanine pigments have been in practice since 1935. It is one of the most important classes of organic pigments. Phthalocyanine pigments have high molar and technical properties - bright and rich color, high coloring power. In countries that are the main suppliers of organic pigments, phthalocyanine pigments account for about 50% of the production of organic pigments. Phthalocyanine pigments form a group of blue and green pigments and are derivatives of phthalocyanine, where the central hydrogen atom can be replaced by a metal. The copper-containing blue phthalocyanine pigment (pigment blue 15) is polymorphic. Five of its crystalline modifications are known: α, β, γ, δ and ε, while the green phthalocyanine pigment has only one crystalline modification. The thermodynamic stability of blue pigment depends on the type of crystalline modification and decreases in the following order: β> ε> δ> α ≈ γ, that is, the greatest stability is characteristic of the β-modification, the least for the α-modification. Phthalocyanine pigments are among the most chemically stable pigments. The high strength of phthalocyanine pigments is based on the symmetrical structure of the molecule. Phthalocyanine pigments have excellent lightfastness and high thermal stability, they are completely insoluble in water, almost insoluble in organic solvents and unusually resistant to chemical reagents. Phthalocyanine pigments are resistant to acids, alkalis and reducing agents. ST. PETERSBURG , 196084, Russia, St. Petersburg, st. Kievskaya, 6, building 1, lit.
