    Abstract: Photographic elements are disclosed comprising a silver halide emulsion layer having associated therewith a magenta coupler and a magenta dye stabilizer compound of the formula S-I: ##STR1## wherein R.sup.0 represents an aryl group or a heterocyclic group; L.sub.1 and L.sub.2 are independently linear alkylene or cycloalkylene linking groups; and R.sup.a and R.sup.b are independently selected substituent groups at least one of which has a .sigma.* value of at least 1.8. Compounds in accordance with formula S-I act as singlet oxygen quenchers and are effective stabilizers for magenta dye images. Photographic elements of the present invention upon exposure and photographic processing yield magenta dye images that have low fading when exposed to light.

    Abstract: A process for the development of color photographic light-sensitive material is described. The process comprises color developing an exposed light-sensitive material in the presence of a compound of the general formula: ##STR1## wherein M is a hydrogen atom, an alkali metal atom, NH.sub.4 or a protective group for the mercapto group which undergoes cleavage by the action of an alkali; R is a hydrogen atom or an alkyl group containing 1 to 3 carbon atoms; and R' is a hydrogen atom or an alkyl group containing 1 to 3 carbon atoms. This process prevents the formation of color development fog without seriously reducing sensitivity.
