A MAGNETIC RECORDING MEDIUM An improved dispersant composition for magnetic media, comprising the reaction product of a phosphate ester and a silicon compound, is described. The silicon compound may be selected from diphenysilanediol or a trialkoxysilane having alkyl, alkenyl, haloaikyl, acryloxypropyl, methacryloxypropyl or phenyl functionality. A magnetic coating composition and a process for producing a magnetic recording medium having improved magnetic properties, which employ the above dispersant composition, are also disclosed. |
