摘要：
Disclosed is a photographic element comprising at least one light sensitive silver halide emulsion layer having associated therewith: (A) a phenolic cyan dye-forming "NB coupler";(B) a high boiling solvent having Formula (II):R.sup.3 OO--C--(--G--)--C--OO--R.sup.4 (II) wherein:R.sup.3 and R.sup.4 represent independently selected alkyl or aryl groups; andG represents an alkyl (including cycloalkyl and aralkyl) containing linking group; and(C) a stabilizer having Formula (III): ##STR1## wherein each Y is an independently selected substituent and m is 0 to 4; andeach T is an independently selected substituent and p is 0 to 4.
