This invention provides compositions which comprise at least one aromatic secondary diamine having a Gardner color number no more than about 6. The aromatic secondary diamine either is in the form of one benzene ring having two secondary amino groups on the ring, or is in the form of two benzene rings connected by an alkylene bridge and having one secondary amino group on each ring. At least one N,N′-dihydrocarbylhydroxylamine is optionally present in the composition. Processes for producing such compositions are also provided.
