    摘要: The invention relates to the preparation of photographic dispersions. The method of the invention consists in preparing a fluid dispersion of an additive in a colloid, congealing the resulting dispersion, subdividing the resulting congealed dispersion into particles, washing the resulting particles, and adding to them a solution of biocide. A dispersion is thus obtained that is protected against the proliferation of micro-organisms during storage.
