The four-layer structure angle-dependent pigments with compositions of Mica/TiO2 /Al2O3/Fe2O3, Mica/TiO2/Al2O3/Cr2O3 and Mica/TiO2/Al2O3/Co2O3 were firstly prepared by the wet-chemical coating method, respectively. The as-prepared pigments were performed by precipitating different metal ions, such as Cr3+, Fe3+, Co2+and Al3+, on the pretreated substrates, mica titanium. The optical effects of four-layer structure pigments were investigated in detail by using the five angles’ spectrophotometer. The angle-dependent spectral reflectance and color changes can be quantitatively measured, and the results show that the angle-dependent effects for the as-prepared pigment were improved by the increasing coated Al2O3 layers.
