Abstract
A process is provided for the pattern dyeing of textile materials wherein dye migration may be controlled by the in-situ formation of a water-insoluble polymeric skin around individual dye droplets when the dye solution is applied to the textile material. The skin is formed by the ionic interaction of an anionic, water-soluble, organic component with a cationic, water-soluble, organic component. Either or both of the components may be a polymeric material.
