MAGNETIC TONER MATERIALS Proposed Classification

mt. CI. G03g 9/00

Magnetic toner materials having low~bulkdensities may be obtained by depositing a magnetically attractable metal in the presence of 1ow~bulkdensity silica particles from solution phase thermal decomposition of transition metal carbonyls. The

particles are then preferably overcoated with an insulating polymer. The magnetic toner particles may be employed in electrostatographic development of latent images, in inks, ferro~fluids, to develop magnetic tape or film and to form a magnetic master.
