Resuspension optimization for photographic nanosuspensions

摘要

A method for storing nanoparticulate suspensions of photographically useful compounds is disclosed that comprises the steps of: providing a suspension of nanoparticulate photographically useful chemical substance in the form of a solid particle dispersion; providing a hydrodynamically optimized container for storing nanoparticulate suspensions comprising a base portion and a body portion unitary with said base portion, said portions defining an interior storage chamber hydrodynamically optimized for the resuspension of sedimented nanoparticulate suspensions, said body portion further comprising a body wall with interior and exterior surfaces; placing said solid particle dispersion in said container; sealing said container and storage chamber against the ambient atmosphere to form a sealed container; storing said sealed container; opening said sealed container; and using a portion of said solid particle dispersion stored in said container to form a coating composition for a light-sensitive element.
