- 3. A 2:1 chrome-complexed yellow dye developer as defined in claim 1 which is represented by the structural formula ##STR35## wherein Y is a hydroquinonyl group.
- 4. A 2:1 chrome-complexed yellow dye developer as defined in claim 1 which is represented by the structural formula ##STR36## where R.sup.3 is hydrogen, hydroxyl, alkyl having from 1-6 carbon atoms or ##STR37## (alkyl having 1-6 carbon atoms) and, --alkylene-- has from 0-6 carbon atoms and R.sup.4 is hydrogen or lower alkyl.
- 5. A 2:1 chrome-complexed yellow dye developer as defined in claim 1 which is represented by the structural formula ##STR38## where n.sup.1 is the integer 1-8; m.sup.1 is the integer 1 or 2 and B is the radical: Serial No. 930,152 ##STR39## where R.sup.5 is hydrogen or hydroxy or, B is the radical; ##STR40## where R.sup.3 is hydrogen, hydroxy, alkyl having from 1-6 carbon atoms or ##STR41## (alkyl having 1-6 carbon atoms); w is the integer 0 or 1; M is ##STR42## and, --alkylene-- has from 0-6 carbon atoms and R.sup.4 is hydrogen or lower alkyl.
