Phthalocyanine Blue (CAS#147-14-8)
quality
Pigment Blue 15:3 is a widely used organic pigment, also known as thicker Danyu blue. It is a blue-blue powdery solid with good tinting and covering power. Here are some of its main properties:
1. Color: Blue 15:3 presents a vivid cyan blue with high chromaticity and transparency. It is often used in pigments to prepare blue and green color palettes.
2. Chemical stability: Blue 15:3 has good chemical stability and is able to maintain its color and properties under different environmental conditions. It is light-resistant, heat-resistant, and less susceptible to chemicals.
3. Solubility: Blue 15:3 has certain solubility in conventional organic solvents, such as alcohols, ketones, esters and aromatic hydrocarbons. But it hardly dissolves in water.
4. Durability: Blue 15:3 has good durability and is not susceptible to problems such as oxidation, pigment decay and fading. It is often used to make products with high requirements for weather resistance, such as coatings, inks and plastics.
It is worth noting that blue 15:3 is a chemically synthesized organic pigment, which may have certain residues or environmental pollution problems compared with natural pigments. Relevant safety operation guidelines should be followed during use, and waste should be disposed of properly. Uses and synthesis methods
Pigment Blue 15:3, also known as Phthalocyanine Blue, is a commonly used organic pigment. Its main use is as a pigment for coloring products such as paints, plastics, inks, rubber, and textiles. It has good hiding properties, lightfastness and weather resistance, and is widely used in various pigment products.
Synthesis method, blue 15:3 is generally obtained by the synthesis of phthalocyanine dyes. The specific steps include:
1. Synthesis of pentaminophthalocyanine metal salt: First, 1,4-dicarbamoylbenzene is reacted with phthalide to obtain diamine compounds. It is then reacted with metal salts under acidic conditions to obtain pentaminophthalocyanine metal salts.
2. Synthesis of phthalocyanine metal salts: pentaminophthalocyanine metal salts are reacted with metal salts such as lithium oxide or titanium tetrachloride to obtain phthalocyanine metal salts.
3. Formation of blue 15:3: The phthalocyanine metal salt is reacted with reagents such as aluminum chloride or sulfur chloride, and under appropriate conditions, a cyclization reaction occurs to form blue 15:3.
This method of synthesis of pigments has been widely used in the chemical industry, and there have been many improved and optimized methods.
Application
Phthalocyanine Blue (C.I. Pigment Blue 15, Copper Phthalocyanine, CuPc, CAS 147-14-8) is a synthetic organic pigment renowned for its exceptionally brilliant blue hue, unrivaled tinctorial strength, and outstanding durability. Introduced commercially in the 1930s, this macrocyclic complex has become the dominant blue pigment across global industries, largely supplanting all other blue colorants in coatings due to its superior performance profile.
In the coatings and paints sector, Phthalocyanine Blue is indispensable for formulating high-performance automotive OEM finishes, industrial paints, powder coatings, and marine coatings. It exhibits excellent lightfastness (rated 7–8), remarkable weather and chemical resistance, and high heat stability, ensuring long‑term color retention even under severe outdoor exposure. Within the printing ink industry, the pigment is a staple for offset inks, water‑based flexo inks, solvent‑based gravure inks, and UV‑curable systems, where it delivers high transparency, excellent rheology, and low viscosity for high‑speed printing. For plastics and polymers, PB15 is widely used to color polyolefins (PP, PE), PVC, PS, ABS, and EVA for applications ranging from toys and household containers to automotive parts and engineering masterbatches, where its non‑migratory nature and high heat stability are critical.
Beyond traditional coloration, Phthalocyanine Blue serves as a high‑purity organic semiconductor in advanced electronics. Copper(II) phthalocyanine functions as a p‑type semiconductor and is incorporated as an electron‑donor layer in organic photovoltaic (OPV) cells, as a charge‑transport layer in organic field‑effect transistors (OFETs), and as a hole‑ or electron‑blocking layer in organic light‑emitting diodes (OLEDs) to enhance device efficiency and lifetime. In textile applications, the pigment is used for dyeing synthetic fibers (polyester, polyamide) and pigment printing on cotton and blends, offering excellent wash fastness and light resistance. In cosmetics, its safety profile permits use in eyeshadows, nail polishes, and other decorative products. The pigment is available in several crystal modifications—α‑phase (red‑shade, PB15:0, PB15:1, PB15:2) and β‑phase (green‑shade, PB15:3, PB15:4)—to meet specific shade, dispersion, and stability requirements.
