Abstract
This invention involves dispersions comprising ionic liquids and a non-ionic surfactant, optionally further comprising a photographically useful compound such as a dye-forming coupler. Such dispersions form coatings that are relatively free of physical defects, and show reduced problems such as crystallization of components like the couplers or ion pairs.
