A solvent dye is a dye soluble in organic solvents. It is usually used as a solution in an organic solvent. [1] 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.

The pure dyes found in modern liquid petroleum dyes are longer alkyl side chain forms of traditional dyes and normally multiple chain length variations of the chromophore are found within a typical commercial liquid petroleum dye. For instance, Sudan Red 462 is a form of Solvent Red 19, with the ethyl side chain replaced by either a 2 ...
Solvent Red 26, also known as Oil Red EGN or C.I. 26120, is a purplish red synthetic azo dye.It is soluble in oils and insoluble in water. Its main use is as a standard fuel dye in the US mandated by the US IRS to distinguish low-taxed or tax exempt heating oil from automotive diesel fuel, and by the EPA to mark fuels with higher sulfur content; it is however increasingly replaced with Solvent ...
Solvent dyes, for wood staining and producing colored lacquers, solvent inks, coloring oils, waxes. Contrast dyes, injected for magnetic resonance imaging, are essentially the same as clothing dye except they are coupled to an agent that has strong paramagnetic properties.

This is illustrated by Reichardt's dye, as shown in the image. Negative solvatochromism corresponds to a hypsochromic shift (or blue shift) with increasing solvent polarity. An examples of negative solvatochromism is provided by 4-(4 ′-hydroxystyryl)-N-methylpyridinium iodide, which is red in 1-propanol, orange in methanol, and yellow in water.
