ABSTRACT:
Silver halide photographic light-sensitive elements comprising a support having coated thereon a coupler dispersion containing layer comprising phenolic cyan dye forming couplers of Formula I and a high boiling organic solvent of Formulas II-V as defined in the specification, wherein the weight ratio in said layer of solvent of formulas II-V relative to coupler of formula I is from 0.1 to 0.5. Such elements provide relatively high cyan coupler reactivity to obtain satisfactory cyan dye density upon processing of the photographic material. ##STR1##
