Abstract

PURPOSE:To constitute a magnetic recording tape with less friction in use and excellent in smooth running performance, by forming a thin film of a specific organic lubricant resin at the back of a base film at nonmagnetic substance layer side of a magnetic tape. CONSTITUTION:For example, at the back of a polyester film (smooth and 25mu thickness), urethane siloxane elastomer is coated as a lubricant resin in a uniform thickness (0.3mu). The urethane elastomer consisting of polyether polyol and including 3wt% siloxane bond in the molecules is excellent in the bonding and wear resistance and also lubricant performance. In comparing two types of magnetic tapes using the lubricant film and unprocessing base film, the surface coarseness is almost unchanged, the friction coefficient is lowered to 1/5-1/10, allowing to constitute a magnetic recording tape with excellent running performance.
