Abstract (en)
[origin: WO0250330A2] The invention relates to a method for coating metal surfaces, excluding lithographic plates, which is characterized in that said method can be carried out in the following order: (a) a step (ii) involving mechanical and/or chemical roughening of the metal surfaces to be coated and (b) a step (iii) involving coating of the roughened surfaces, wherein a layer with a thickness ranging from 100 nm to less than 1 mm is applied or (c) introducing a secondary phase as step (ii) at the same time as coating step (iii), wherein a layer with a thickness ranging between 100 nm and less than 1 mu m is applied.
