Ftalocyaninegrood

Ftalocyaninegrood, commonly referred to as phthalocyanine red, is a class of synthetic organic pigment based on a copper phthalocyanine core that produces a red shade. It is part of the broader family of phthalocyanine pigments, which are prized for their brightness, lightfastness, and chemical stability. Red shade variants are widely used in art supplies and industrial coatings and are typically marketed under trade codes such as PR254 and PR255 in many color systems.

Chemical structure and origin: these pigments derive from copper phthalocyanine and are engineered with substitutions that shift their color toward red. The result is a pigment that combines high tinctorial strength with excellent resistance to light, heat, and many chemicals. The exact shade can vary from bluish-red to more neutral red depending on formulation and particle size.

Properties: phthalocyanine red pigments are typically transparent to semi-transparent with high tinting strength, allowing for strong color in thin layers. They exhibit exceptional lightfastness and weather resistance, making them suitable for outdoor and long-life applications. They are generally insoluble in water and most solvents, existing as pigment particles dispersed in a binder rather than as true chemical dyes.

Applications: these pigments are widely used in artist paints (oil, acrylic, and watercolor), printing inks, automotive and industrial coatings, and plastics. Their versatility, durability, and lower toxicity compared with many traditional red pigments have contributed to their broad adoption.

Safety and handling: as with most pigment powders, breathing dust should be avoided; standard safety practices apply during handling and processing. They are not considered highly toxic in typical use, but long-term exposure should still be managed.
