Abstract

Transfer films consist essentially of a support film, a release layer and a transfer layer detachable from this release layer and composed of two magnetic layers and said transfer films may have, on the second magnetic layer, an adhesive layer which serves for fixing the transfer layer to a substrate, the two magnetic layers each containing a magnetizable material having a different coercive force.
