Abstract

To prepare a transfer metallization film which is metallized on one side, the first application of a metal layer to one side of the film web is preceded by a one-sided electric corona discharge applied to the other, not-to-be-metallized, side of the film web. The second and any further application of a metal layer on the same side of the film are not preceded by a corona discharge step.
