    摘要： Polymeric porous particles have a continuous solid phase and at least two different internal pores that are isolated from each other within the continuous phase. At least one set of discrete pores contains a marker material, and some instances, each set of discrete pores contain different pores marker materials that are isolated from each other. These marker materials are detectably different from each other. The porous particles can be spherical or non-spherical and can be used in any situation where the detectably different marker materials can be evaluated.

    摘要： Crosslinked polymeric organic porous particles have a crosslinked organic solid phase and discrete pores dispersed within the crosslinked organic solid phase, which discrete pores are isolated from each other. The crosslinked organic porous particles are prepared using one or more water-in-oil emulsions containing a polyfunctional reactive compound and a reagent that causes crosslinking, and can be incorporated into or applied to various articles for many purposes. If marker materials are incorporated into the crosslinked organic porous particles, these marker materials can be detected using appropriate instruments.

    摘要： A surface decorated particle including a core particle phase having an outer surface; and fine inorganic particles on the outer surface of the core particle phase; wherein the fine inorganic particles have hydrophobic groups covalently bonded primarily on portions of surfaces of the fine inorganic particles positioned away from the core particle phase. Such surface decorated particles are obtainable by a method including stabilizing dispersed hydrophobic phase particles in an aqueous phase with fine inorganic particles having a relatively hydrophilic surface; and treating the stabilized dispersed hydrophobic phase particles with a hydrophobic group containing reactant to form hydrophobic groups covalently bonded to surfaces of the fine inorganic particles. In a particular embodiment, such surface decorated particles are obtainable by a limited coalescence process for preparing binder polymer particles using inorganic stabilizer particles that provide a plurality of surface bonding sites and reacting such sites with a plurality of alkoxy silane moieties that contains pendant hydrophobic groups.

    摘要： An electrophotographic method for producing fused toner images on a receiver medium comprising the steps of: forming an electrostatic image pattern on an image forming member; developing the image pattern on the image forming member with fusible toner particles thereby forming a toner image thereon; transferring the toner image to the receiver medium; and heating the toner image to form a fused toner image on the receiver medium, wherein an amount of a plasticizer is added to the toner particles of the toner image after formation of the toner image on the image forming member and prior to or concurrent with fusing of the transferred toner image on the receiver medium, further wherein the amount of plasticizer added is effective in lowering the Tg of the toner below that of the toner under prevailing ambient conditions in the absence of the added plasticizer. The current invention overcomes the limitations of the prior art because the plasticizer is added immediately before fusing, thus avoiding toner clumping upon storage, as well as eliminating the high cost associated with a custom manufactured receiver that already contains plasticizer.
