Abstract
PURPOSE: To provide a magnetic paint containing soybean lecithin and a phosphoric acid ester, and giving a magnetic tape having high coercive force, max. magnetic flux density and squareness ratio, and excellent gloss.
CONSTITUTION: The objective paint is prepared by adding soybean lecithin and a phosphoric acid ester to a magnetic paint. For example, soybean lecithin is dispersed in a mixture of magnetic powder and a solvent; a binder and other optional additives are added and mixed to the dispersion; and finally a phosphoric acid ester is added to the mixture.
EFFECT: Suitable for the mass production of magnetic tape at low cost. Resistant to gelation.
