    摘要: Magnetic printing apparatus for forming on a substrate a colored print of an original colored design, said apparatus comprising a ferromagnetic printing means which is imposed on an electrically conductive support; means for forming on the ferromagnetic printing means a magnetic image of a photocolor-separated film positive of the original colored design; means for developing the magnetic image on the ferromagnetic printing means with a toner comprising a ferromagnetic component, a dye and a resin; means for transferring the developed image to the substrate, and means for neutralizing static electricity on said toner. Optionally, the apparatus may include: means for transferring the developed image from one substrate to another; means for fixing said dye on and/or in an ultimate substrate; and/or means for removing said ferromagnetic component and said resin.

    摘要: A process for reproducing graphic information wherein a magnetic image is formed in a premagnetized layer of acicular chromium dioxide by heating the chromium dioxide selectively to above its Curie point. Uncharged ferromagnetic toner particles are then applied uniformly to the chromium dioxide layer, but adhere only in the magnetized areas. The toner particles are then transferred electrostatically to a substrate.
