Résumé : |
Pigments based on the layer-substrate interference principle are the most important types of pearlescent pigments today. Most of them consist of metal oxide layers coated on mica, a sheet layer silicate mineral. But mica pigment characteristics are limited to the thickness. Two new synthetic materials could be used in place of mica as substrates for effect pigments. New coloristic effects can be realized by suitable combination of silica flakes or alumina flakes as carrier and coating with relatively high index metal oxides such as titanium dioxide and iron oxide. |
