Abstract: This invention comprises dispersion comprising a solvent having dispersed therein a liquid-crystal forming dye of structural Formula I: [D-(X)m]-(Y)n wherein: D is a light-absorbing chromophore other than a cyanine dye or a barbituric acid oxonol dye; each Y contains an ionic or a nonionic solubilizing substituent or a group with a pKa value of less than 4 in water; each X is a nonionic substituent; n is 0 to 10; m is 0-10; and the resulting dye forms a liquid-crystalline phase in solvent. The dispersion is particularly useful in imaging and photographic elements.

Abstract: Disclosed is a photographic element having a reduced rate of crystal formation comprising a silver halide emulsion layer having associated therewith:(a) a phenolic cyan dye-forming "NB coupler";(b) a first high boiling solvent having Formula (IV):G--C--OO--R.sup.1 (IV)wherein:R.sup.1 is an alkyl or aryl groups; andG is an alkyl (including cycloalkyl and aralkyl) containing linking group; and(c) one or more second high boiling solvents selected from phosphates, phosphonates, phosphine oxides, sulfoxides, and carbonamides, said second high boiling solvent being present in amounts (by weight) sufficient to reduce crystal formation in a dispersion of the coupler compared to a dispersion of the same coupler in a dispersion where the second solvent is replaced with a like amount of the first solvent.

Abstract: This invention describes the coprecipitation of nanoparticulate pharmaceutical agent dispersion via a process that comprises the dissolution of the said pharmaceutical agent in combination with a crystal growth modifier (CGM) in an alkaline solution and then neutralizing the said solution with an acid in the presence of suitable surface-modifying surface-active agent or agents to form a fine particle dispersion of the said pharmaceutical agent, followed by steps of diafiltration clean-up of the dispersion and then concentration of it to a desired level. This process of dispersion preparation leads to microcrystalline particles of Z-average diameters smaller than 400 nm as measured by photon correlation spectroscopy. Various modification of precipitation schemes are described, many of which are suitable for large-scale manufacture of these agent dispersions.
