Variation of aluminum flake orientation in wet metallic films with time has been determined using a newly-developed noncontact-type colorimeter equipped with a light source and two detectors at properly selected angles. In spray application, aluminum flakes are oriented parallel to the film surface during spraying and drying. During spraying, the flakes are oriented by the paint droplet flow only when the droplet containing the flakes is large enough to penetrate the wet film as a buffer layer and spread out on the substrate surface. During drying, the flakes are oriented by the shrinkage of the film thickness caused by the evaporation of volatiles.
