| titleOfInvention | METHOD OF DISPERSING HYDROPHOBIC YELLOW COUPLERS |
| abstract | The invention relates to a process for the dispersion of hydrophobic yellow couplers which are used for the production of photographic silver halide color materials. The object and the object of the invention are a method for the mechanical dispersion of yellow couplers with aliphatic ballast group, the storage-stable dispersants provides that no Truebungserscheinungen, z. As by recrystallization of the coupler, and its constituents do not affect the absorption of the image dye formed during photographic processing. The process according to the invention consists in carrying out the dispersion of the yellow coupler dissolved in a low-boiling solvent in the presence of an aminogenic surfactant and an aminopolycarboxylic acid (formula s, claim 1). As the surfactant, a hydrophilic yellow coupler is advantageously used. |
