ABSTRACT:
A composition consisting of (A) an aromatic amine of the formula R--NH.sub.2 wherein R is a monosubstituted or disubstituted phenyl radical in which one substituent group is an alkoxy group of 1 to 4 carbon atoms in one of the positions ortho and para to the NH.sub.2 group and the other substituent is an alkyl group of 1 to 4 carbon atoms or a chlorine atom in any position on the benzene ring, the former substituent group is present when the radical is both monosubstituted and disubstituted while the latter substituent is present only when the radical is disubstituted, (B) from about 0.001 to about 0.20 percent by weight of a heterocyclic compound containing 2 to 8 carbon atoms, 2 to 3 sulfur atoms, 1 to 2 heterocyclic nitrogen atoms, at least 2 hydrogen atoms and a single heterocyclic ring with 2 or more carbon atoms, 1 to 2 nitrogen atoms and 1 to 2 sulfur atoms with the substituents on the nitrogen atoms being restricted to hydrogen atoms, and (C) from about 0.001 to about 0.02 percent by weight of a metal complexing agent selected from the group consisting of aliphatic, cyclicaliphatic and aromatic compounds of no more than about 22 carbon atoms and containing at least two carboxyl groups.
This invention also comprises the composition consisting of components (A), (B) and (C) combined with (D) from about 0.05 to about 0.5 percent by weight of a compound selected from the group consisting of compounds of the formula R'R"N--NH.sub.2 and R'NH--NHR" wherein R' and R" can be the same or different and are selected from the group consisting of hydrogen atoms and alkyl groups of 1 to 4 carbon atoms.
