    摘要: The present invention relates to magnetic toners and processes for producing them. The toner materials that are produced have the color of the magnetic material substantially obscured while still maintaining the high percentages of magnetic materials necessary for many types of magnetic printing processes. Further, the toners may be provided with a desired shade or color with dyes or pigments. The process of production preferably involves the coating of the individual magnetic particles with low-density essentially opaque polymeric particulate material having an affinity for the magnetic particles, thereby obscuring the color of said magnetic particles. The resulting coated particles may be intermixed with dyes, pigments, binders and other material as desired to produce toners which are useful for a variety of purposes, including multi-color reproduction techniques.
