Preparing color toner images with metallic effect
Abstract:
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.
