Abstract

The invention relates to a multilayer coating consisting of a conversion layer which is located on a metal and a layer with a dyeing effect which is located on said conversion layer; and to the use thereof. According to the invention, the conversion layer has pores and the second layer located on the conversion layer is obtained by applying a solution containing at least one alkoxysilane compound and a dye which is soluble in a polar solvent, then polymerising and/or cross-linking the alkoxysilane compound.
