Abstract

PURPOSE:To obtain a squeal-free magnetic recording medium while lessening a secular change during magnetic paint adjustment, by using a specific setting component and a surface active agent. CONSTITUTION:Magnetic paint containing a setting component, such as isocyanate containing 20-80wt% isoholodiisocyanate, and a surface active gant consisting of fatty acid monoglyceride shown by the right general formula (where R is an alkyl group) is applied onto a base and dried to obtain a magnetic recording medium.
