Solvent Blue 122

Solvent Blue 122 is a high-performance synthetic dye belonging to the anthraquinone class. It is primarily used as a solvent dye for coloring non-polar organic solvents, hydrocarbon-based products, plastics, waxes, oils, and coatings. It offers excellent solubility in organic solvents and strong tinting strength, making it ideal for industrial applications requiring bright and stable blue coloration.

TRADE NAME:

Transparent Blue S-R,Solvent Navy Blue S-R

What Are the Core Characteristics and Advantages of Solvent Blue 122?

Solvent Blue 122 exhibits a series of excellent properties derived from its anthraquinone molecular structure (chemical formula: C₂₂H₁₆N₂O₄, molecular weight: 372.37) . Its primary advantages include:

• ‍Superior Color Performance: It presents a bright reddish-blue (navy) hue with high color purity and transparency. The color strength is stable at 100±1 (relative to the standard sample), and the color difference (△E) is controlled within ≤0.50, ensuring consistent coloring effects.
• Excellent Thermal and Light Stability: It has a melting point of approximately 210℃ and can withstand processing temperatures up to 300℃ in polystyrene (PS) and ABS plastics . Its light fastness reaches grade 7-8 in full-shade applications and grade 6-7 in tinted systems, meeting long-term outdoor use requirements.
• Good Solubility and Migration Resistance: Almost insoluble in water but highly soluble in organic solvents. In polymer systems, it shows minimal migration tendency, preventing dye bleeding or penetration into contact materials.
• Strong Chemical Stability: It demonstrates grade 4-5 resistance to 5% hydrochloric acid and 5% sodium hydroxide solutions, maintaining color stability in acidic and alkaline processing environments.
• Low Impurity Content: Compliant with HG/T 4410-2012 standard, its ash content ≤0.20%, moisture ≤0.30%, and DMF insoluble matter ≤0.20%, avoiding negative impacts on substrate performance.‍

Application:

main used for Wood stains, Aluminium, Polyester & metals foils, Printing inks, Stationery inks, Glass,Plastic & Metal coatings, Leather & Plastic coloration/finishing etc.

What Are the Specific Applications of Solvent Blue 122?

Benefiting from its comprehensive performance, Solvent Blue 122 is widely applied in plastics, fibers, inks, and other fields, with the following key application scenarios :

Plastic Coloring:

Preferred for engineering plastics and general-purpose plastics such as PS, ABS, PC, PET, and PMMA. It is especially suitable for transparent or semi-transparent plastic products like electronic device casings, automotive interior parts, and food packaging materials.

Synthetic Fiber Dyeing:

Mainly used for mass-coloring of polyester (PET) fibers, producing high-color-fastness textile materials for clothing, home textiles, and industrial fabrics.

Ink and Coating Industry:

Applied in solvent-based inks for packaging printing and automotive coatings, providing bright colors and excellent weather resistance.

Other Fields:

Used in coloring wax products, rubber, and certain industrial oils, expanding its application scope with stable performance.
