Abstract
The present invention relates to preprimed metal substrates suitable for use in formed metal applications. The preprimed metal substrate is coated with, as primer layer, (1) a first coating layer applied onto the metal substrate, the first coating layer being based upon a particular hydroxyl group-containing block copolymer, and (2) at least one flexible subsequent coating layer applied onto the first coating layer. The preprimed metal substrates are especially useful in automotive applications.
