Abstract:
The dust-free coated dye-containing pellet is a granulated carrier material that is encapsulated with a dye-containing coating material. The dye-containing coating material contains a mixture of a water-soluble or water-dispersible film-former with at least one direct dye and/or at least one oxidation dye precursor. Preferred carrier materials include dextrose, oligosaccharides and cellulose compounds. The dust-free coated dye-containing pellet is preferably made by granulating the carrier material together with optional antioxidants and auxiliary agents, heating the resulting granulate at no more than 34° C., subsequently coating the granulate by spraying it with a solution or dispersion of the coating material and optionally drying as needed.
