摘要：
The present invention provides a method of forming a dispersion of solid particles of a dye in a gelatin medium which includes the steps of milling the solid dye in the present of a glycerophospholipid dispersant in an aqueous medium and diluting the resulting dispersion with an aqueous solution containing a gelatin. In addition, a photographic element is provided comprising a support having coated thereon at least one silver halide emulsion layer and at least one additional gelatin layer that contains a dispersion of solid particles of a dye and a glycerophospholipid dispersant.
