Abstract: A composite color toner image can be enhanced in a printed receiver material by having a separate fluorescing magenta toner image applied over it to provide a “pinkish” fluorescing effect. This separate fluorescing magenta toner image is obtained using visible fluorescing dry magenta toner particles, each of which has a polymeric binder phase and a visible fluorescing colorant that emits at one or more peak wavelengths of from 510 nm and to and including 590 nm. The covering power of the fused visible fluorescing magenta toner particles in the enhanced composite color toner image is at least 350 cm2/g to and including 1100 cm2/g, and the covering power of each of the non-fluorescing cyan, non-fluorescing yellow, non-fluorescing magenta, and non-fluorescing black toner particles in the enhanced composite color toner image is at least 1500 cm2/g to and including 2300 cm2/g.

Abstract: A method is used to provide a toner image with a metallic effect. After forming a latent image, it is developed with metallic dry toner particles to form a developed toner image that is transferred and fixed to a receiver material. Each metallic dry toner particle consists essentially of a polymeric binder phase and non-conductive metal oxide particles. Before fixing, the metallic dry toner particle has a mean volume weighted diameter (Dvol) of at least 15 ?m and up to and including 40 ?m. The non-conductive metal oxide particles are present in an amount of 20-50 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, before fixing, is greater than 0.1 and up to and including 10.

Abstract: A fluorescing dry toner particle comprises a polymeric binder phase comprising a non-fluorescing binder polymer and a polymeric fluorescing colorant dispersed within the non-fluorescing binder polymer. The polymeric fluorescing colorant comprises a fluorescing moiety that is covalently attached to a colorant polymer that is the same or different than the non-fluorescing binder polymer, but the polymeric fluorescing colorant is blendable with the non-fluorescing binder polymer to form a homogeneous polymeric binder matrix, and is present in an amount of at least 1 weight % and up to and including 40 weight %, based on the total fluorescing dry toner particle weight. These fluorescing dry toner particles can be used in various dry developers to provide fluorescing toner images with or without non-fluorescing color toner images.

Abstract: Images produced by electrophotography are often subjected to harsh conditions, such as high temperature and high relative humidity conditions. Prints when subjected to face-to-face stacking under these conditions tend to stick and are difficult to separate without damage. Ethylene-bis-stearamide is incorporated in a protective toner formulation employing a toner binder having a higher glass transition temperature than that of the conventional CYMK colored image toners employed to provide a protective layer in fused images. Further, ethylene-bis-stearamide does not interfere with typical oil release additives used in fuser rollers. By combining ethylene-bis-stearamide with polyalkane waxes having a weight average molecular weight of equal to or greater than 2000 and a poly dispersity of less than 2.0, addition protection can be realized.

Abstract: When color images are printed on a substantially transparent substrate, such as a transparency film, or on a highly colored substrate, the color properties of image may be compromised. When color images are printed on a substantially transparent substrate, the images do not have the maximum possible color saturation because a large portion of the incident light is not reflected back. As a result, images appear to be dull and lower in contrast. When color images are printed on highly colored substrates, the color properties of the image are also influenced by the color of the substrate. In order to enable printing on such substrates, an opaque toner was developed which comprises predispersed inorganic filler with a refractive index of greater than 1.75.
