Abstract
A composition which is useful for preparing a magnetic recording medium is prepared by homogeneously mixing components comprising a magnetic powder, a resin binder and a partial hydrolyzate of an organosilicon compound which contains at least two silicon-bonded hydrolyzable groups and at least one carbon-bonded amino group. When conventionally applied to a substrate to provide the magnetic recording media, the compositions of this invention provide a magnetic layer which is more durably attached to the substrate. Improved magnetic recording media, such as magnetic tapes, are thereby provided.
