Summary:The invention relates to a non-color shifting multilayer structure and protective coating on the same, and specifically, provides a color pigment of an omni-directional structure comprising a protective coating. The segment comprises a first layer of a first material and a second layer of a second material, and the second layer extends accross the first layer. In addition, when the segment is exposed to wide-band electromagnetic radiation and is observed at the angle of 0-45 degrees, the segment reflection has reserved full width at half maximum (FWHM) of below 300nm and an electromagnetic radiation band of reserved color shifting of below 30 degrees. The segment comprises a weathering coating which covers the external surface of the segment and makes the relative photocatalytic activity of the segment reducing at least 50%. 本发明涉及无色移的多层结构及其上的保护涂层。具体地，提供了具有保护涂层的全向结构的色颜料。所述颜料具有第材料的第层和第二材料的第二层，所述第二层延伸横过第层。此外，当将颜料暴露至宽频电磁辐射并由介于0°和45°之间的角度对所述颜料进行观察时，所述颜料反射具有小于300nm的预定半峰全宽(FWHM)和小于30°的预定色移的电磁辐射频带。所述颜料具有覆盖其外表面并使所述颜料的
