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.

Oil or solvent dye is used in applications such as foil printing, printing inks, marking pens, ball point pens, candles and other waxes, polishes, leathers, wood stains, acrylic resins, varnishes and shellacs. They are used in signaling smoke and in the pyrotechnics industry. These dyes are also used to color lubricants in the automotive and industrial cutting industries. However, the most frequent application of solvent dyes is in the plastics industry. Within the industrial plastics community, solvent-based dyes are used to color a variety of solid materials, such as acetates, nylon, polyester, acrylics, PVC, PMMA, PETP, polystyrene and styrene monomers. In addition, many solvent dyes are used as components by the biological stain manufacturing community to produce stains that will identify various cell structure components in medical diagnostics and scientific research.
