Solvent Dyes are characterized by their solubility in organic solvents or plastics. When used with an organic solvent, the dyeing process takes place in a solution. The molecules of solvent dyes are non-polar (or have a small amount of polarity). This means that the dying process does not take place through ionization (as is the case with other types of colorants like acid dyes). For this reason, solvent dyes are typically insoluble in water.
The naming of solvent dyes has been standardized, following the pattern of the color of the dye (and a distinguishing number) coming after the word “solvent.” For example, multiple shades of red solvent dyes are differentiated by the number at the end of the name (i.e. “Solvent Red 1,” Solvent Red 49,” Solvent Red 24,” Solvent Red 111,” etcetera).
