The invention relates to a process for the dispersion of hydrophobic photographic additives, in particular for the dispersion of hydrophobic color couplers in aqueous gelatin or other hydrophilic binders. The aim of the invention is an improved process for the dispersion of hydrophobic photographic additives. According to the invention, the object is achieved in that the high-boiling solvents alkylsulfonic acid dialkylamides and / or alkylsulfonic acid monoalkylamides of the general formula ## STR1 ## be used, where R & ind1 !, R & ind2 !, R & ind3! Hydrogen, an alkyl group having preferably 4 to 10 carbon atoms or a cyclic group, R & ind3 !, R & ind4! Represent hydrogen, an alkyl group having preferably 1 to 8 carbon atoms or a cyclic group. The dispersions are characterized by an improved storage stability and reduced recrystallization tendency of the dissolved additives. The method is suitable for the production of silver halide-containing color materials. |
