Abstract
A process is described for printing dyes onto 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 which is substantially sublimable at less than 215.degree. C., and resin which substantially encapsulates the ferromagnetic component and the dye component; transferring the developed image to a substrate comprising a continuous belt comprising a thermally stable, dielectric, non-dye-receptive material; transferring the developed image by heat and pressure to film of a thermally stable resin which is permeable to said dye component laminating paper or a film to the image bearing side of the film, and bringing the laminated film into contact with a textile material to be dyed while the film and fabric are rotated upon a heated drum, to thereby transfer said dye component from the film or films to the textile material. In a preferred aspect of the invention another film is laminated to the side of the film supporting the image and the dye is simultaneously sublimed to two textile materials several times.
