Abstract

To estimate the gonioapparent properties of metallic and pearlescent paint finishes, samples of metal-flake and pearl-mica pigmented paint surfaces were prepared. For these samples, spectral reflectance factors for various geometric conditions were measured by gonio-spectrophotometer. From these spectral reflectance factors, colorimetric values were calculated. Furthermore, spectral reflectance factors were treated by principal component analysis, and flake orientation in the paint layer was supposed.
