Abstract

Coated magnetic carrier materials for electrostatic copying prods. having adequate breakdown strength and propensity for electrostatic charging are prepd. by coating iron powder with a uniform 2-8 micron layer of gamma-aminopropyl -triethoxy-silane from a mixed solvent-aq. phase soln. The single uniform polymer layer on the surface of the magnetic particles ensures a favourable dipole system for the developer dyes in copying technology.
