摘要:
This invention relates to a composition of matter comprising a functionalized mordant polymer comprising a cationic polymer having an adsorbed metal-ion sequestrant, wherein the metal-ion sequestrant has a stability constant greater than 1010 with iron (III). It further relates to an article comprising said composition and a method of removing target metal-ions from an environment comprising contacting the environment with said composition.

Disclosed is a color silver halide photographic element comprising a support bearing: (1) a light sensitive silver halide emulsion layer; (2) a nitrogen heterocycle with a minimum of three heteroatoms that does not react with oxidized developer, does not contain free thiol substituents, and has a ClogP sufficient to increase the photographic speed of said element compared to the same element without the compound, said heterocycle compound located either in said light sensitive layer or in a layer adjacent to it; and (3) a light reflecting silver halide material; provided that the heterocycle compound and the light reflecting material are located either (a) in different layers of the element located close enough to each other so that a super-additive speed increase is realized or (b) in the same light sensitive layer. The invention provides improved light sensitivity.
摘要:
An x-ray detector, detection assembly, and method of using the detector and detection assembly. The detector is used with an x-ray source and has a converter including a mass of prompt emitting radiographic phosphor particles and a photoconductive binder. The mass of particles is dispersed and embedded in the binder. The phosphor absorbs x-rays emitted by the source and emits longer wavelength actinic radiation responsive to the x-rays. The photoconductive binder absorbs the actinic radiation and produces electron-hole pairs responsive to the actinic radiation.

Disclosed in this specification is an aqueous dispersion for treating a textile. The dispersion generally includes surface-functionalized inorganic oxides in combination with a fluorochemical. Significantly lower concentrations of fluorochemicals are present in comparison to prior art dispersions.
摘要:
A method for inhibiting growth of microbes in a liquid having a pH equal to or greater than about 2.5 by using a filter bed assembly or filter for filtering the liquid having a metal-ion sequestering agent for removing designated metal ion from the liquid. The liquid is passed through the filter bed or filter for a sufficient time so as to substantially reduce the designated metal ion from the liquid.
