ABSTRACT:
Photographic coupler solvents which are solid at ordinary temperature are described for incorporation in photographic emulsions and elements. The solvents are employed in combination with a cyan dye forming coupler of the specific phenol type and a discoloration inhibitor of the dihydroxybenzene ether type to improve long-term preservability of the developed cyan dye particularly by exposure to mild heat and humidity.
