A silver halide photographic element comprising a light sensitive silver halide containing layer which also contains a 2-equivalent pyrazolone magenta coupler, a thiomorpholine dioxide compound which has an alkoxy substituted aryl group substituent on the ring nitrogen, a compound of formula (I) below, and a hydroquinone compound of formula (R) below: ##STR1## wherein: R.sub.3, R.sub.4 and R.sub.31 are independently an alkyl group or H; R.sub.11, R.sub.12 and R.sub.21 are alkyl groups. The presence of the compound (I) when used with the two-equivalent pyrazolone magenta coupler and compounds (R) and (S), can result in a photographic element with low printout and/or thermal discoloration problems.
