    摘要： The present invention is an imaging element which includes a support, an image forming layer superposed on the support; and an antistatic layer superposed on the support. The antistatic layer includes electrically conductive particles at a 10-60 volume percent and microgel particles. The microgel particles are composed of 25 to about 80 weight percent of an oleophilic monomer, 5 to about 45 weight percent of a hydrophilic monomer, and 0 to 20 weight percent of a crosslinking monomer having at least two addition polymerizable groups. In an alternative embodiment the antistatic layer also includes a binder.

    摘要： A stable aqueous dispersion of magnetic particles contains a dispersant having an HLB number of at least 8. The dispersion is prepared by milling an aqueous slurry of magnetic particles until there are substantially no agglomerates of magnetic particles present. The dispersion can be used to prepare magnetic recording elements and, in particular, photographic elements having a transparent magnetic recording layer.

    摘要： Semi-permeable particle can be used to facilitate chemical reactions such as catalytic reactions. The semi-permeable particles are permeable to molecules having a molar mass of 1000 Daltons or less and have a mode particle size of at least 1 μm. The semi-permeable particles have multiple discrete cavities containing an aqueous solution or suspension of an organic catalytic material. The semi-permeable particles are also impermeable to the organic catalytic materials so they are retained within the multiple discrete cavities, and the semi-permeable particles can be reused multiple times for the same or different chemical reaction.

    摘要： Crosslinked organic polymeric porous particles have a crosslinked organic solid phase and discrete pores dispersed within the crosslinked solid phase which pores are isolated from each other. These porous particles are prepared using one or more water-in-oil emulsions containing a polyfunctional reactive compound, a reagent that causes crosslinking, optionally an ethylenically unsaturated polymerizable monomer, and optionally an organic solvent, and can include various marker materials.
