Abstract

PURPOSE: To increase the wearing properties by mixing the perphloro alkyl polyether and the prescribed aliphatic alcohol as the lubricant into the magnetic layer.
CONSTITUTION: The magnetic coating material composed of the magnetic powder and the binding agent is coated on the substrate such as the polyester film or the like to form the magnetic layer and then to obtain the magnetic tape and the like. Then the double-component system lubricant featuring, for example, 70:30W99.5:0.5 weight ratio between the perphloro polyether and the aliphatic alcohol of the carbon number 12W20 is mixed into the magnetic layer of the above mentioned magnetic tape. The wearing properties can be enhanced more by using the nonmagnetic powder featuring the Mohs' hardness of over 6 together. The quantity of the lubricant to be used is set preferably to 1W25 part by weight to 100 of the magnetic powder, and the nonmagnetic powder is set to 0.5W5wt% to the magnetic powder respectively.
