The invention relates to a method for introducing water-insoluble or poorly water-solublenphotographic ingredients in aqueous colloidal solutions, in particular a method of preparationnstable, finely divided dispersions which are added to a halide silver-containing photographic emulsionncan. The introduction of the water-insoluble or poorly water-soluble photographic ingredientsntakes place without the use of energy-intensive high-speed dispersing and there are only small amountsnused on surfactants and no other stabilizing additives. According to the inventionnbecomes the organic solution of the water-insoluble or sparingly water-soluble photographic ingredients,ncontaining at least one simultaneously oil and water-soluble compound, with the aqueous colloid solutionnbrought into contact so that at least one of the solutions in vorzerteilter form under trainingncurved boundary surfaces voriiegt. |
