Abstract
A process is described for dyeing a textile material, comprising the steps of: forming a latent magnetic image in a magnetic imaging member comprising a ferromagnetic material on an electrically conductive support; developing the magnetic image by applying thereto a ferromagnetic toner comprising a ferromagnetic component, a dye component containing a dye which is substantially sublimable at from 160.degree. C. to 215.degree. C., and a resin, which substantially encapsulates the ferromagnetic component and the dye component; transferring the developed image to a first surface of a thermally stable sublimable-dye-permeable polymeric film; bringing the polymeric film on a second surface thereof into contact with a textile material to be dyed; heating the textile material and polymeric film to thereby transfer the dye image from the first surface of the polymeric film through the polymeric film to form a dye image in the textile material.
