SOLVENT DYE
solvent dye is a dye soluble in organic solvents. It is usually used as a solution in an organic
solvent.
Solvent dyes are used to color organic solvents, hydrocarbon fuels, waxes, lubricants, plastics,
and other
hydrocarbon-based nonpolar materials. Fuel dyes are one use of solvent dyes. Their
molecules are typically nonpolar or little polar, and they do not undergo ionization. They are
insoluble in water. They form a colloidal solution in solvents. They have poor (basic dyes) to
good (metal complex based) light fastness.
Red and yellow solvent dyes are often azo dyes, green and blue ones tend to
be anthraquinone dyes.
Solvent dyes are used for gold imitation (and other transparent metallic effects) of metallized
polyester films. Also used in marking inks, inkjet inks, glass coloration, and so on.
