A metal sheet, inclusive of a metal strip, having a front side and a back side, both the front side and the back side comprising a first coating having an average thickness in the range from 0.5 to 10 &#x3bc;m, wherein the first coating of the front side contains particles, which release divalent or multivalent metal ions upon the action of an acid, in such an amount that a self-depositing coating agent forms, upon contact with the front side, a second coating thereon, whereas this is not the case for the first coating of the back side. The first coating of the front side can be overcoated with a self-depositing coating agent. Cut edges that do not have a first coating can be covered with the self-depositing coating agent. Correspondingly coated metal sheets, as well as a method for the manufacture thereof, are furthermore within the scope of the invention.
