Sulphosol liquid dyes are developed from the Sulphol Dyes by a solubilisation process and are characterized by their complete solubility in water, whilst maintaining the many advantages of the conventional Sulfur dye. It has negligible free sulfides content. In water solution they are virtually non-substantive, a property which makes them useful for many specialized dyeing techniques.
