Solvent Dyes “ Description

Solvent dyes are a class of non-polar dyes that are soluble in organic solvents but generally insoluble in water. They are widely used for coloring oils, waxes, plastics, hydrocarbons, and other non-polar materials. These dyes provide bright, transparent colors and are known for their excellent solubility and good heat stability.

Key Characteristics of Solvent Dyes:

• Solubility: Soluble in organic solvents (e.g., alcohol, ether, hydrocarbons) but not in water.

• Color Range: Available in a wide spectrum of vivid colors such as yellow, red, blue, orange, and green.

• Transparency: Produce transparent shades, which are useful for certain plastic and ink applications.

• Heat Resistance: High thermal stability, making them suitable for high-temperature processing like in plastic molding.

• Lightfastness: Varies depending on the specific dye; generally moderate to good.
