    摘要： An ink jet printing method comprising the steps of: a) providing an ink jet printer that is responsive to digital data signals; b) loading the printer with an ink jet recording element comprising a substrate having thereon an image-receiving layer comprising an inorganic, anionic pigment, an organic, anionic binder and an organic, cationic mordant, and a porous overcoat layer located over the image-receiving layer, the porous overcoat layer comprising an inorganic pigment and an organic, anionic, binder, wherein the refractive index of the inorganic pigment in the overcoat layer is at least 0.05 refractive index units less than the refractive index of the inorganic, anionic pigment in the image-receiving layer; c) loading the printer with an ink jet ink composition; and d) printing on the recording element using the ink jet ink in response to the digital data signals.

    摘要： A process for the preparation of nanoscale particulate material is described comprising: (i) combining one or more functional material to be precipitated as nanoscale particles and one or more surface active material in a compressed CO2 phase with a density of at least 0.1 g/cc, where the functional material is substantially insoluble in the compressed CO2 in the absence of the surfactant, the surfactant comprises a compressed CO2-philic portion and a functional material-philic portion, and the compressed CO2 phase, functional material and surfactant interact to form an aggregated system having a continuous compressed CO2 phase and a plurality of aggregates comprising surfactant and functional material molecules of average diameter less than 10 nanometers dispersed therein; and (ii) rapidly depressurizing the compressed CO2 phase thereby precipitating the dispersed functional and surfactant materials in the form of composite particles of average diameter from 0.5 to less than 10 nanometers.
