[Preparation and spectra characterization of optically variable pigments with four symmetrical configurations].
The optically variable pigments with four symmetrical configurations were obtained by using the mica titanium as the host materials, which was pretreated in acid and alkaline condition. The reflection differences between the host materials and the coatings were increased by optimizing the number of layers and the arrangement order. The optically variable effect was investigated by X-Rite MA86II five angles spectrophotometer. The impact of symmetrical configurations on improving the color travel effect was studied, and the influence of different coating materials on the hue and the color travel effect was researched. The results show that the reflection rate and the color travel effect of the pigment were improved by coating another material on three symmetrical configurations.
