ABSTRACT:
A process is described for printing dyes onto 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 a ferromagnetic toner comprising a ferromagnetic component, a dye component which is substantially sublimable at from 160.degree. C. to 215.degree. C., transferring the developed image to a substrate comprising a continuous belt comprising a thermally stable, dielectric, non-dye-receptive material; covering the developed image with a layer of a thermally stable resin which is permeable to said dye component bringing the continuous belt into contact with a textile material to be dyed while the belt and fabric are rotated upon a heated drum, with the textile material facing the covering layer of resin of the continuous belt, to thereby transfer said dye component from the continuous belt to the textile material; washing and drying the continuous belt.
