Polymer Dyes are characterized by their solubility in organic solvents or plastics. The molecules of polymer 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, Polymer dyes are typically insoluble in water.Solvent dyes are fairly versatile and used in various applications. Polymer is commonly used in various plastics, petrol,hydrocarbons, oils, candles, waxes, automotive,ink and inkjets, wood staining and coating industries.
