Abstract

본 발명은 분산제가 필요없는 자성층을 구성하는 것으로서 자성층 구성 결합제 성분중에서 -SO3H, -COOH 및 -OH기로 구성되는 군으로부터 선택된 관능기를 말단에 4 내지 6몰% 함유하는 결합제를 전체 결합제 100중량부당 20 내지 30중량부 포함하는 것이며 이로부터 수득하는 자기기록매체는 전자특성, 내구성 및 물리적특성이 우수하다.The present invention constitutes a magnetic layer that does not require a dispersant, and includes a binder containing 4 to 6 mol% at the end of a functional group selected from the group consisting of -SO 3 H, -COOH, and -OH among the magnetic layer constituent binder components, and 100 wt% of the total binder. 20 to 30 parts by weight of the magnetic recording medium obtained therefrom is excellent in electronic properties, durability and physical properties.
