A dyestuff is a colourful material that, when applied to a substrate in aqueous solution, has an affinity for that substrate. Dyes come in two varieties: natural and synthetic. Although natural dyes were mostly used in the past, synthetic dyes now make up a larger portion of the Dyestuff sector. Azo dyes, cyanine dyes, nitroso dyes, anthraquinone dyes, and others are examples of many forms of synthetic dyestuff. The insoluble substance known as dye has uses in paper, paints and coatings, food, leather, metals, and textiles.
A colourful substance known as Dyestuff includes both dyes and pigments. A dye is a coloured chemical, either natural or artificial, that is typically applied in an aqueous solution to give fabrics their hues. The textile, leather, and paper sectors utilise dyes the most. These substances are soluble, and when they come into contact with something else, their crystal structure is momentarily disrupted by adsorption and mechanical retention due to the creation of ionic or covalent bonds.
