【摘要】 |
|
An optically variable pigment was produced by wet chemical method, where TiO2-coated mica with interference colors acted as the substrate materials. The structure of the pigment was characterized by X-ray diffraction (XRD), and its optically variable effect was investigated by X-Rite MA86 II five angles spectrophotometer. The impact of different interference substrate materials for improving the color travel effect was studied, and the influence of white and black background on the hue and the color travel effect were studied. Results showed that optically variable pigments can be prepared by coating Cr2O3 on the surface of the pretreated TiO2-coated mica. The color travel effect was sensitive to the change of substrate materials, and different backgrounds can influence the hue and the color travel effect of the pigment. |
