摘要： An iron oxide pigment having a coating of a silane of the formulaR.sub.n Si(OR').sub.4-nwhereinR is an, in some cases, branched or oxygen-bridge-containing alkyl or alkenyl moiety of 1 to 18 carbon atoms, or an aryl moiety,R' is an, in some cases, branched and, in some cases, oxygen-bridge-containing alkyl moiety of 1 to 8,N=1 to 3,Or a hydrolysis product thereof; a magnetic tape containing such coated iron oxide pigment and a process for coating such iron oxide pigment. There is particularly disclosed the treatment of iron oxide magnetic pigments to thereby improve their wear resistance and dispersibility in organic mediums.
