What are solvent dyes?
Solvent dye is a kind of dye that can be dissolved in organic solvents Dye is a very commonly used type of dye. It is insoluble in water and can only be dissolved in organic solvents or oils. Its ability to mix and dissolve with solvents is due to the non-polar nature of dye chemicals. The molecules of solvent dyes are usually non-polar or weakly polar, do not ionize, and they form colloidal solutions in solvents; they have poor (basic dyes) to good (Metal complex dyes) Lightfastness.
The ability of solvent dyes to completely dissolve is very important for the uniform dyeing of the dyed object. Importantly, solutions that easily dissolve in other chemicals are called solvents. Unlike other colorants, solvent dyes are not susceptible to ionization, which is the ability of a compound to change polarity by gaining or losing an electron from another compound. This is why solvent dyes are insoluble in water, a very polar substance.
