Abstract: A latex used for the preparation of toner particles by emulsion aggregation is prepared, using a controlled addition of anionic surfactants, without the use of a nonionic surfactant. Such a process comprises preparing an aqueous phase using a limited amount of anionic surfactant; preparing an emulsion of monomers in water with additional anionic surfactant and without a nonionic surfactant; adding a portion of the emulsion to the aqueous phase to initiate seed polymerization, in the presence of an initiator, to form seed polymer; and adding the remaining monomer emulsion to the composition to complete polymerization to form a latex polymer.

Abstract: A lithographic printing plate for use on a printing press, with minimal or no additional processing after exposure to actinic radiation, comprises a printing plate substrate, a polymeric resist layer capable of imagewise photodegradation or photohardening, and a plurality of microencapsulated developers capable of blanket-wise promoting the washing out of either exposed or unexposed areas of the polymeric resist. The microencapsulated developers may be integrated into the polymeric resist layer, or may form a separate layer deposited atop the polymeric resist layer, or may be coated onto a separate sheet support capable of being brought into face-to-face contact with conventional printing plates.

Abstract: The continuous process for manufacturing toners disclosed herein includes continuously feeding components of a toner composition into a feed section of a screw extruder at a controlled rate. The continuous process for manufacturing toners may include feeding the components of a toner composition into the feed section of a screw extruder without performing an external or secondary dispersion step. That is to say, the components of the toner composition may be fed directly into the extruder without using dispersions of individual components as used in batch processes. Rather, the toner components are added to the extruder in dry form, melt-mixed, and may be dispersed in aqueous form in the extruder. The process may produce micron-sized toner particles, thus no further size reduction may be necessary.

Abstract translation: 本文公开的用于制造调色剂的连续方法包括以受控的速率将调色剂组合物的组分连续进料到螺杆挤出机的进料段中。 用于制造调色剂的连续方法可以包括将调色剂组合物的组分进料到螺杆挤出机的进料部分中，而不进行外部或二次分散步骤。 也就是说，调色剂组合物的组分可以直接进料到挤出机中而不使用分批方法中使用的各个组分的分散体。 相反，调色剂组分以干燥形式加入到挤出机中，熔融混合，并且可以以水性形式分散在挤出机中。 该方法可以产生微米级的调色剂颗粒，因此不需要进一步的尺寸减小。

Abstract: A process for making toner particles is provided. In embodiments, a suitable process includes melt mixing a resin in the absence of an organic solvent, optionally adding a surfactant to the resin, adding to the resin at least one colorant and other optional toner additives, adding to the resin a basic agent and water to form a mixture, and subjecting the mixture to acoustic mixing at a suitable frequency to form to form an emulsion. A phase inversion may then be performed to create a phase inversed emulsion including a disperse phase comprising molten resin and the optional ingredients of the toner composition, at which time toner-sized droplets may be solidified from the disperse phase into toner particles, which can be recovered for use.
