3D structural siliceous color pigments |
摘要 |
The invention relates to particles with opalescent effect-especially 3-D structural color pigments-based on solid colloidal crystals of monodispersed spheres and the manufacturing processes suitable for large-scale production of such solid colloidal crystal products. The particles with opalescent effect contain a sphere based crystal structure (or super-lattice) built up by monodisperse spheres and one or more secondary types of much smaller colloidal particles occupying partially or completely the empty spaces between the monodisperse spheres.
