Abstract

A magnetic recording medium is disclosed in which dispersion characteristics of magnetizable particles in a magnetic paint is improved which results in improved saturation magnetic flux density and squareness ratio. The dispersion characteristics is improved by the treatment of magnetizable particle with a titanium alcoholate compound having at least one group easy to be hydrolyzed and at least one oleophilic group hard to be hydrolyzed in an organic solvent.
