This study describes in a quantitative manner the relationships between coating structure and optical properties. Scattering coefficient, gloss and pore volume were measured after applying different blends of polystyrene spheres using various amounts of binder to transparent Mylar film. The coatings were prepared using four proportions of two sizes of polystyrene spheres and varying amount of two binders, starch and latex respectively. Optical properties of coatings were related to changes in coating structure. A scanning electron microscope was used to observe the structure and to facilitate void size measurement. The void size distribution correlated very well with the scattering and gloss values. Micrographs of the coating surface showed an apparent increase in pigment particle size at low levels of binder addition. The coatings with latex had higher gloss than with starch..
