Abstract
The present invention relates to decorative coatings for plastic substrates, the decorative coatings ideally being stable and durable coatings that are spectrally tunable to permit the selection of a variety of appearances, and ideally providing a decorative metal finish. More particularly the present invention provides for a plastic substrate having a decorative coating including a spectrally controlling system and a stress controlling system. The spectrally controlling system includes alternating absorbing layers and transparent layers, and the stress controlling system controls the overall residual stress of the decorative coating to within a desired range.
