The present invention relates to decorative coatings for plastic substrates, the decorative coatings ideally being stable and durable coatings that are spectrally tuneable 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. Further provided are methods for applying to a plastic substrate a decorative coating having a spectrally controlling system and a stress controlling system. 本发明涉及用于塑料基材的装饰涂层，所述装饰涂层理想地是稳定的且耐用的涂层，其是光谱可调的以允许选择多种外观，并且理想地提供装饰金属表面处理。更特别地，本发明提供具有包括光谱控制系统和应力控制系统的装饰涂层的塑料基材。所述光谱控制系统包括交替的吸收层和透明层，所述应力控制系统将所述装饰涂层的整体残余应力控制在理想的范围内。进步提供具有光谱控制系统和应力控制系统的装饰涂层应用至塑料基材的方法。
