Abstract
강자성 분말, 카본블랙, 연마제, 결합제 및 기타 첨가제를 포함하는 자성층을 비자성 지지체 상에 형성시킨 자기기록매체에 있어서, 하기 구조식을 갖는 아인산 화합물을 폴리염화비닐계 결합제에 대한 열안정제로서 사용함으로써 내구성 및 전자변환특성을 향상시킨 자기기록매체와 그의 제조방법.In a magnetic recording medium having a magnetic layer comprising ferromagnetic powder, carbon black, an abrasive, a binder, and other additives formed on a nonmagnetic support, durability by using a phosphorous acid compound having the following structural formula as a heat stabilizer for a polyvinyl chloride binder And a magnetic recording medium having improved electron conversion characteristics and a method of manufacturing the same.
(상기식에서, R1, R2, 및 R3은 각각 탄소수 3 내지 12의 포화탄화수소기를 나타낸다.)(In the formula, R 1 , R 2 , and R 3 each represent a saturated hydrocarbon group having 3 to 12 carbon atoms.)
