Opacity improvement in films can be derived from kaolins by three mechanisms: 1 particle packing allowing air-filled voids to affect enhanced light scatter; 2 reduced calendaring to achieve high gloss. Thus the coating is not compacted to eliminate air-filled voids; 3 increased light scatter affected by large differences in refractive indices of components.
