ABSTRACT:
1,3-Disulfonylcycloalkanes substituted in the 2-position with at least one hydrogen atom are employed as silver halide complexing agents in both conventional and diffusion transfer photography. Preferred compounds are those possessing an S-containing moiety substituted in the 2-position and particularly those containing 6, 7 or 8 members in the cyclic ring and substituted in the 2-position with R.sup.2 -S--CH.sub.2m wherein R.sup.2 is a hydrocarbon radical and m is a whole number 0 to 5. The latter thioether-substituted 1,3-disulfonylcycloalkanes comprise the novel compounds of the present invention.
