摘要： The present invention provides a method for the preparation of a UV curable electrostatographic toner. The process includes the steps of dispersing a polymeric material and a UV curable material and a UV photoinitiator in an organic solvent to form an organic phase. The organic phase is dispersed in an aqueous phase containing a particulate stabilizer to form a dispersion. The dispersion is homogenized and the organic solvent is removed from the dispersed particles in the dispersion which are then recovered.

摘要： The present invention is a method for the preparation of electrostatographic toner including the following steps. A polymer material is dissolved in an organic solvent to form an organic phase. The organic phase is dispersed in an aqueous phase that includes a particulate stabilizer and a salt including an anion selected from chloride, oxychloride, sulfate, perchlorate, nitrate, dihydrogen phosphate, lactate, trifluoromethylsulfonate, and trifluromethylhydrate and a cation selected from aluminum, iron (III), tin (II) and zirconium (IV), to form a dispersion. The dispersion is homogenized. The organic solvent is evaporated from the dispersion and the resultant product is recovered, washed and dried. In an alternate method the salt is added directly to the dispersion.

摘要： The present invention provides a method of printing which includes providing a substrate having an inked surface. The inked surface is typically achieved using an offset lithographic printing press. A thermoplastic polymer powder is applied to the inked surface. The surface is then fused. An advantage of the prepared substrate is that there is reduced contamination of electrostatographic fusing systems when fused by heat and pressure fixing. Another aspect of the invention further provides a method of fusing a substrate having an inked surface wherein a thermoplastic powder has been applied to the inked surface prior to stacking the uncured offset prints.

摘要： A composite color toner image can be enhanced by applying a separate fluorescing toner image over it to provide an enhanced color toner image having a “pinkish” fluorescing effect. This separate fluorescing toner image is obtained using visible fluorescing dry magenta toner particles. Each of these toner particles consists essentially of a polymeric binder phase and a visible fluorescing colorant that emits at one or more peak wavelengths of at least 510 nm and up to and including 590 nm and that is dispersed within the polymeric binder phase.

In the method, a continuous layer of the dry toner is applied to a substrate in a desired shape of an antenna via an electrophotographic printing process, and subsequently the toner is fused to the substrate by heating the toner above its glass transformation temperature. The dry toner for use in producing an antenna for an RFID device comprises toner particles having a resistance allowing triboelectric charging or a resistance allowing inductive charging. The toner particles comprise a polymeric binder and metallic particles, wherein said metallic particles are nanoparticles having a mean particle size below approximately 500 nm in at least one direction.
