Photographic element with new singlet oxygen quenchers

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.
