ABSTRACT:
The present invention is concerned with the use of aniline derivatives of the general formula: ##STR1## wherein R.sub.1 is a hydrogen atom or a lower alkyl or aryl radical, R.sub.2 is a hydrogen atom or a lower alkyl radical which can be substituted by hydroxyl, amino, carboxyl, lower alkoxycarbonyl, lower alkanoylamido, aryl lower alkyl or aryl or by a group of the structure: ##STR2## in which R.sub.5 and R.sub.6 have the meanings given hereinafter, R.sub.3 is a hydrogen or halogen atom or a carboxyl group, R.sub.4 and R'.sub.4, which can be the same or different, are hydrogen or halogen atoms, carboxyl groups or lower alkoxy radicals or lower alkyl radicals which are preferably in the m-position and R.sub.1 and R.sub.4 or R.sub.2 and R.sub.4 or R.sub.4 and R'.sub.4, when the two substituents are ortho to one another, can together form a saturated or unsaturated hydrocarbon chain containing 2 to 6 carbon atoms which can be substituted by hydroxyl or oxo groups, R.sub.5 is a hydrogen atom or a lower alkyl radical and R.sub.6 is a hydroxyl group or a lower alkoxy, lower alkyl or aryl radical; and of the salts thereof with acids and bases
