Abstract
1,262,653. Incorporating couplers into photographic emulsions. ILFORD Ltd. July 16, 1969 [July 24, 1968], No.35339/68. Heading G2C. Photographic colour couplers which contain a carboxylic acid group, or a group capable of yielding such a group and of forming an alkalimetal salt, are incorporated into gelatino-silver halide emulsions by reacting a solution of the alkali-metal carboxylate salt of the coupler with a solution of water-soluble calcium, barium, strontium or magnesium salt in the presence of gelatine or a colloid compatible with gelatine, e.g. polyvinyl alcohol, to form a dispersion of the Ca, Ba, Sr or Mg salt of the coupler in the colloid medium and incorporating said dispersion into the emulsion. Phenol may be present during the reaction. Couplers capable of yielding a carboxylic group include those containing a phthalimide or succinimide ring which opens in alkali.
