Abstract

Disclosed is a photographic element comprising a light sensitive silver halide emulsion layer having associated therewith a yellow dye-forming coupler having formula I: ##STR1## wherein PA1 each A is independently a divalent group selected from the divalent groups consisting of aryl and --C(R.sup.1)(R.sup.2)--, in which each R.sup.1 and R.sup.2 is independently selected from the group consisting of hydrogen, alkyl, alkoxy, aryloxy, heterocyclic, and aryl groups, and one A can be joined to form a ring with another A or with R.sup.3, and m is from 2 to 6; PA1 R.sup.3 is selected from the group consisting of hydrogen, alkyl, heterocyclic, and aryl groups, provided that R.sup.3 may form a ring with A or is a group joined to R.sup.4 to form a heterocyclic five- or six-membered ring; PA1 R.sup.4 is selected from the group consisting of aryl, heterocyclic, and alkyl groups and may form a heterocyclic ring bonded to R.sup.3 ; PA1 Y is selected from the group consisting of --SO.sub.2 --, --C(.dbd.O)--, --C(.dbd.O)NR.sup.9 R.sup.10 --, --C(.dbd.O)O--, and --P(.dbd.O)(OR.sup.9)(OR.sup.10 --) where R.sup.9 and R.sup.10 are independently H or an alkyl or aryl group; and PA1 the remaining substi…
