Diphenylamines having the formula ##SPC1## Wherein: Y represents a member selected from the group consisting of a hydroxy and amino, R.sub.1 and R.sub.3, each independently, represent a member selected from the group consisting of hydrogen, halogen, lower alkyl, lower alkoxy, a ureido residue, and -NHCOR wherein R is lower alkyl, R.sub.2 represents a member selected from the group consisting of hydrogen, halogen, lower alkyl, lower alkoxy, a ureido residue, -NHCOR wherein R is lower alkyl, and --NHR.sub.8 wherein R.sub.8 represents a member selected from the group consisting of hydrogen, lower alkyl, lower hydroxyalkyl and carbamyl lower alkyl, with the proviso that when R.sub.2 is --NHR.sub.8, R.sub.3 is not hydrogen R.sub.4, R.sub.5, R.sub.6, and R.sub.7 each independently represent a member selected from the group consisting of hydrogen, halogen, lower alkyl and lower alkoxy, with the proviso that when Y is hydroxy, R.sub.2 is not hydrogen, halogen, lower alkyl or alkoxy and that when Y is amino, at least two of R.sub.1, R.sub.2 and R.sub.3 are other than a hydrogen and R.sub. 2 is not hydrogen when R.sub.4, R.sub.5, R.sub.6 and R.sub.7 are all hydrogen and the acid addition salts of said diphenylamines.
