Abstract
A substrate has an abrasion-resistant diffusion barrier layer system having: a hard base layer including a coating composition based on a polymer containing reactive surface groups; and a nanostructured topcoat obtained by applying a nanoscale composition comprising sol particles and/or particulate solids to the basecoat and then curing it. The system features good abrasion resistance and diffusion barrier effect, and is particularly suitable as a protective coat for plastic substrates.
