A series of experiments was carried out to investigate
the relationship between the microstructure and the
appearance of coated materials using confocal laser
microscopy and optical scattering metrology.
Microstructural properties such as surfaces roughness,
pigment particle size and size distribution affect
optical scattering distribution of the sample, resulting
in different appearances. In this presentation,
preliminary research on two pigmented coating systems -
TiO2 and metallic-flake pigmented coatings - are
presented. By integrating measurements and modeling, a
methodology for predicting the appearance of a coating
from its microstructure and constituents is proposed.
