摘要： A low-specular-reflectance coating composition includes a binder, a solvent, and a plurality of substantially spherical particles having a multimodal particle size distribution. The multimodal particle size distribution has two or more modes, each mode having a peak defining an associated mode particle size, wherein the distribution function includes a first mode having a first peak corresponding to a first particle size, and a second mode having a second peak corresponding to a second particle size. A ratio of the second particle size to the first particle size is between 1.7-4.0. A smallest of the mode particle sizes is greater than or equal to 1.0 microns, and a largest of the mode particle sizes is greater than or equal to 3.0 microns.

摘要： A color toner image with a metallic effect can be prepared by forming one or more latent images and developing them with metallic dry toner particles and color toner particles. The developed color toner image can be transferred to a receiver material, and fixed to provide a color toner image with a metallic effect. The metallic dry toner particles have a polymeric binder phase and non-conductive metal oxide particles dispersed therein. Before fixing, the metallic dry toner particle has a mean volume weighted diameter (Dvol) 15-40 μm and the non-conductive metal oxide particles are present in an amount of at least 20-50 weight % based on total metallic dry toner particle weight. The ratio of the metallic dry toner particle Dvol to the average equivalent circular diameter (ECD) of the non-conductive metal oxide particles in the metallic dry toner particles is greater than 0.1 and up to and including 10.
