The vibrant world of industrial inks relies heavily on the quality and performance of its constituent colorants. Solvent Black 5, a well-established nigrosine dye with CAS number 11099-03-9, stands out as a preferred choice for manufacturers seeking deep, rich black coloration. Understanding its key properties is crucial for optimizing ink formulations and ensuring consistent print quality. As a dedicated supplier of fine chemicals from China, we aim to provide insights into why this dye is indispensable for many ink applications.

The Chemical Profile of Solvent Black 5
Solvent Black 5 is characterized by its excellent solubility in alcohols and other organic solvents, which is fundamental to its use in solvent-based ink systems. Its chemical structure allows for efficient dispersion, leading to stable ink formulations that resist settling and agglomeration. The dye's high purity, typically 98% or more, directly contributes to the intensity and clarity of the black color produced, preventing dullness or unwanted undertones that can occur with lower-grade colorants.

Critical Properties for Ink Formulation
For ink manufacturers, the performance attributes of Solvent Black 5 are paramount:

  • Color Strength and Depth: The high concentration of chromophores in our Solvent Black 5 ensures a profound, opaque black, essential for applications like printing inks for packaging, labels, and specialty markers.
  • Solvent Compatibility: Its solubility in alcohols and other organic solvents allows for easy integration into a wide range of ink bases, including lacquers and solvent-borne coatings. This compatibility ensures smooth application and excellent film formation.
  • Thermal Stability: With a melting point well above 300°C, Solvent Black 5 can withstand the moderate heat encountered during some printing processes and drying stages without degrading, maintaining its color integrity.
  • Lightfastness: While specific ratings vary by formulation, nigrosine dyes generally offer good to moderate lightfastness, suitable for many indoor and some outdoor applications.
  • Dispersion Properties: Fine particle size and excellent dispersibility prevent clogging of printing nozzles and ensure uniform color distribution on the substrate.
