摘要： 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.

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： 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.
