PROCESS FOR THE PREPARATION OF ABRASION RESISTANT NONDUSTING AND WATER-SOLUBLE DYESTUFF PARTICLES IN A FLUIDIZED BED

摘要

Abrasion-resistant, non-dusting, water-soluble dye particles are prepared by spraying dye solution, which optionally contains formulation auxiliaries, onto dye particles in a fluidised bed. The stream of gas required to create the fluidised bed must be able to take up moisture.
