    摘要: Colloidally stable dispersions of a spectral sensitizing dye are formed directly in water without the use of an organic solvent. The process of the invention involves mixing the dye particles with water to form a slurry and then homogenizing or milling the slurry at an elevated temperature in the presence of a surfactant to form finely divided particles uniformly dispersed in the water.
