To improve the light stability of dyestuff by incorporating the coupler for forming the magenta dye having a ballasting group possessing phenylsulfonyl-phenoxy group in an silver halide emulsion layer.
This photographic element is provided with the silver halide emulsion layer containing the dye-forming coupler represented by formula I in which X is and H is atom or a group releasable by coupling; R' is a tertiary alkyl group; and R" is a group represented by formula II, and in formula II, each of R1-R3 is, independently, an alkyl group and optional 2 of them may combine with each other to form a ring; R4 is an H atom or a substituent and when R4 is a substituent, R3 and R4 may combine with each other to form a ring; and W is a substitutent of formula III in which each of Ra and Rb is an H atom or an alkyl or aryl group; Rc is a substituent; each of Rd and Re is, independently, a substituent; and each of (s) (t) is an integer of 0-4.
