Abstract:
A bis-o-aminophenol or bis-o-aminothiophenol of the structure ##STR18## in which A.sup.1 to A.sup.3 are--independently of one another--H, CH.sub.3, OCH.sub.3, CH.sub.2 CH.sub.3, or OCH.sub.2 CH.sub.3,T is O or S,and Z is one of the following carbocyclic or heterocyclic aromatic radicals; ##STR19## where Q=C--A or N, and A=H, F, (CH.sub.2).sub.p CH.sub.3, (CF.sub.2).sub.p CF.sub.3, O(CH.sub.2).sub.p CH.sub.3, O(CF.sub.2).sub.p CF.sub.3, CO(CH.sub.2).sub.p CH.sub.3, CO(CF.sub.2).sub.p CF.sub.3 where p=0 to 8 (linear or branched chain), OC(CH.sub.3).sub.3, OC(CF.sub.3).sub.3, C.sub.6 H.sub.5, C.sub.6 F.sub.5, OC.sub.6 H.sub.5, OC.sub.6 F.sub.5, cyclopentyl, perfluorocyclopentyl, cyclohexyl or perfluorocyclohexyl,where, in the isolated aromatic rings, a maximum of 3 N-atoms may be present per ring and only 2 N-atoms may be adjacent, and, in the fused ring systems, a maximum of 2 N-atoms may be present per ring,M=a single bond, (CH.sub.2).sub.n, (CF.sub.2).sub.n, CH(CH.sub.3), CH(CF.sub.3), CF(CH.sub.3), CF(CF.sub.3), CH(C.sub.6 H.sub.5), CH(C.sub.6 F.sub.5), CF(C.sub.6 H.sub.5), CF(C.sub.6 H.sub.5), C(CH.sub.3)(C.sub.6 H.sub.5), C(CH.sub.3)(C.sub.6 H.sub.5), C(CF.sub.3) (C.sub.6 H.sub.5), C(CF.sub.3)(C.sub.6 F.sub.5), C(C.sub.6 H.sub.5).sub.2, C(C.sub.6 F.sub.5).sub.2, CO, SO.sub.2, ##STR20## provided that when Z= ##STR21## at least one Q group of the bis-o-aminophenol must be N or C--A where A is other than H, and when Z= ##STR22## with Q being C--F and M being a single bond, the amino groups of the bis-o-aminophenol must be positioned ortho or para to the oxygen bridge, provided further that, in the bis-o-aminothiophenol, when T in TH is S and Q is C--A with A being H, M when present is not (CF.sub.2).sub.n or CF(CF.sub.3).
