    Abstract: A process for the manufacture of non-dusting dye granules from an aqueous formulation of highly dispersed water-insoluble dyes by spraying the formulation, which contains adhesive compounds, into a fluidized bed of pulverulent dispersing agent, dye or mixture thereof. The resulting granules possess excellent redispersibility, which is important in using them.
