Abstract

본 발명은 베이스 필름위에 자성분을 함유한 자성도료가 도포되어 있는 비디오용 자기 기록 매체에 있어서, 하기 일반식(I)로 표시되는 알킬 아릴 설포네이트 화합물계 커플링제가 자성분에 대하여 0.1∼2.0중량% 함유되어 있는 비디오용 자기 기록 매체이며, 알킬 아릴 설포네이트 화합물계 커플링제가 자성분 표면에 있는 수산기와 자발적인 재배열 화학결합을 하여 이차적인 자성도료 제조시 투입되는 우레탄 결합제와도 상용성이 좋아져 테이프 내구성 및 분산성을 향상시킨다.The present invention relates to a magnetic recording medium for a video coated with a magnetic paint containing a magnetic component on a base film, wherein the alkyl aryl sulfonate compound-based coupling agent represented by the following general formula (I) is 0.1 to 2.0 with respect to the magnetic component. It is a magnetic recording medium for video that contains by weight%, and the alkyl aryl sulfonate compound coupling agent is compatible with the urethane binder used in the manufacture of the secondary magnetic paint by spontaneous rearrangement chemical bonding with the hydroxyl group on the magnetic surface. Improves tape durability and dispersibility.
