    摘要: A photographic element comprises a support having thereon a layer containing a hydrophilic vehicle having dispersed therein a particulate polymeric material encapsulated with a chelating or already chelated polymer, said element, when the polymer is not already chelated, comprising a source of metal ions. The elements are useful in diffusion transfer processes, and particularly useful with chelating acid dyes or dye-forming materials to provide a metallized dye image.

    摘要: The invention provides new crosslinked vinyl polymer particles, new coating compositions containing such particles, new liquid electrographic developers containing such particles, new electrographic elements containing one or more layers comprising such particles, and new electrographic records containing toner images and/or layers comprising such particles.The polymeric particles of the invention are characterized in that each particle has an average diameter less than one micrometer and comprises a crosslinked vinyl addition copolymer obtainable by aqueous emulsion polymerization of a mixture of monomers wherein:1.5-15 percent by weight of the mixture of monomers comprises polyfunctional vinyl addition-polymerizable monomers in order to form crosslinking structural units in the copolymer;85-98.5 percent by weight of the mixture of monomers comprises monofunctional vinyl addition-polymerizable monomers selected such that:A. 0-98.5 percent by weight of the mixture of monomers comprises monofunctional monomers, the homopolymers of which would be insoluble in but swellable by an isoparaffinic hydrocarbon liquid;B. from 0 to less than 85 percent by weight of the mixture of monomers comprises monofunctional, monomers, the homopolymers of which would be soluble in the isoparaffinic hydrocarbon liquid; andC. 0-60 percent by weight of the mixture of monomers comprises monofunctional monomers, the homopolymers of which would be insoluble in and not swellable by the isoparrafinic hydrocarbon liquid;with the provisos that:I. if more than 0 percent by weight of the mixture of monomers comprises the monomers of part C., above, than more than 0 percent by weight of the mixture of monomers comprises the monomers of part B., above;II. if more than 9 percent by weight of the mixture of monomers comprises the monomers of part C., above, then less than 10 percent by weight of the mixture of monomers comprises the monomers of part A., above; andIII. all of the polyfunctional and monofunctional monomers and amounts thereof are selected such that the copolymer would be insoluble in the isoparaffinic hydrocarbon liquid but would be swellable by that liquid.
