    摘要： A method of forming a color filter is provided. The method includes providing a mixture of a color filter material and a compressed fluid; providing at least a partially controlled environment for retaining a substrate, the at least partially controlled environment being in fluid communication with the mixture of the color filter material and the compressed fluid; providing a shadow mask in close proximity to the substrate retained in the at least partially controlled environment; and chargably releasing the mixture of the color filter material and the compressed fluid into the at least partially controlled environment, wherein the color filter material becomes free of the compressed fluid prior to contacting the substrate at locations defined by the shadow mask thereby forming a patterned deposition on the substrate.

    摘要： A process for the preparation of a radiation-sensitive silver halide emulsion comprised of high chloride cubical silver halide grains containing from 0.05 to 3 mole percent iodide, based on total silver, where the iodide is incorporated in the grains in a controlled, non-uniform distribution forming a core containing at least 50 percent of total silver, an iodide free surface shell having a thickness of greater than 50 Å, and a sub-surface shell that contains a maximum iodide concentration is disclosed, the process comprising: (a) providing in a stirred reaction vessel a dispersing medium and host high chloride silver halide cubical grains comprising a speed enhancing amount of iodide, and (b) precipitating silver halide onto the host grains by introducing at least a silver salt solution into the dispersing medium at a rate such that the normalized molar addition rate, Rn, is above 3.0×10−2 min−1, Rn satisfying the formula: Rn=[Qf×Cf]/M where Qf is the volumetric rate of addition, in L/min, of silver salt solution into the reaction vessel; Cf is the concentration, in moles/L, of the silver salt solution; and M is total moles of silver halide in the host grains in the reaction vessel at the precise moment of addition of the silver salt solution. In a further aspect, this invention is directed towards a photographic recording element comprising a support and at least one light sensitive silver halide emulsion layer comprising silver halide grains prepared as described above. The advantages of the invention are generally accomplished in accordance with the discovery that when the exterior portion of profiled silver iodochloride grains are grown under specific conditions of high molar addition rates, iodochloride emulsions of enhanced sensitivity and photographic curve shape are produced, as speed can be increased while keeping fog to a low level.

    摘要： A process for the deposition of particulate material of a desired substance on a surface includes: (i) charging a particle formation vessel with a compressed fluid; (ii) introducing into the particle formation vessel a first feed stream comprising a solvent and the desired substance dissolved therein and a second feed stream comprising the compressed fluid, wherein the desired substance is less soluble in the compressed fluid relative to its solubility in the solvent and the solvent is soluble in the compressed fluid, and wherein the first feed stream is dispersed in the compressed fluid, allowing extraction of the solvent into the compressed fluid and precipitation of particles of the desired substance; (iii) exhausting compressed fluid, solvent and the desired substance from the particle formation vessel at a rate substantially equal to the rate of addition of such components to the vessel in step (ii) through a restrictive passage to a lower pressure whereby the compressed fluid is transformed to a gaseous state and a flow of particles of the desired substance is formed; and (iv) exposing a receiver surface to the exhausted flow of particles of the desired substance and depositing a uniform layer of particles on the receiver surface.
