ABSTRACT:
Fluorocarbon dye dispersion comprising an organic disperse dye; a certain normally liquid fluorocarbon having a fluorine to carbon atom ratio of at least 1.5, a solubility parameter of not greater than 7.0 and a critical temperature of at least 135.degree. C., and, optionally, an effective amount of a compound having both surface activity and solubility in the normally liquid fluorocarbon, said dye dispersion being useful in the exhaust dyeing of disperse dyeable synthetic polymers, in the form of films, fibers or fabrics, by the process comprising contacting the polymer with the dye disperson at a temperature above the glass transition temperature of the polymer for a sufficient time to exhaust the dye onto the polymer.
