Phthalocyanine Green G (PG7)is a dark green powder at room temperature, insoluble in water and common organic solvents. It is a fully chlorinated copper phthalocyanine compound with extremely stable chemical properties, exhibiting outstanding lightfastness (Grade 7-8), heat resistance (180-200°C), weather resistance, and resistance to acids and alkalis. Based on these exceptional properties, it is one of the most important high-performance green organic pigments. It is widely used in applications demanding high color durability, including the coatings (such as automotive paints), inks, plastics, rubber, synthetic fibers, as well as pigment printing pastes and stationery products.
