Abstract

PURPOSE:To obtain a magnetic layer which has superior dispersibility, surface smoothness and magnetic characteristics, by mixing a titanium coupling agent with a magnetic paint. CONSTITUTION:To a magnetic paint consisting of ferromagnetic powder and a binder, a 0.1-10wt% titanium coupling agent shown by the formula and based upon the magnetic powder is added, and a base is painted with the resulting mixture to obtain a magnetic recording medium.
