Description

Aniline Blue (Spirit Soluble) is a synthetic triphenylmethane dye known for its solubility in alcohol and other organic solvents. This property makes it a versatile and essential colorant for applications where water-based systems are unsuitable. It is primarily utilized in industries requiring high-intensity coloration of non-aqueous materials, such as inks, lacquers, and specialized biological stains.

Application

• Ink Manufacturing: As a key pigment for spirit-based inks, stamp pad inks, and flexographic printing inks.
• Wood Stains & Lacquers: For coloring wood finishes, polishes, and transparent coatings where alcohol solubility is required.
• Biological Staining: Used in histology and microscopy as a component of specialized stains, such as Mallory's connective tissue stain.
• Plastics & Polymers: For coloring certain types of plastics and synthetic resins dissolved in organic solvents.
• Fuel & Oil Marking: As a dye for non-aqueous fluids like heating oil or industrial solvents for identification purposes.
• Paper Coatings: In specialty paper coatings and decorative finishes that utilize solvent-based systems.
