Abstract

Use of metal complex compounds of formula[LnMemXp]zYq,  (1)wherein Me is manganese, titanium, iron, cobalt, nickel or copper, wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, R10 and R11, are each independently of the others hydrogen; unsubstituted or substituted C1-C18alkyl or aryl; cyano; halogen; nitro; —COOR12 or —SO3R12 wherein R12 is in each case hydrogen, a cation or unsubstituted or substituted C1-C18alkyl or aryl; —SR13, —SO2R13 or —OR13 wherein R13 is in each case hydrogen or unsubstituted or substituted C1-C18alkyl or aryl; —N(R13)—NR′13R″13 wherein R13, R′13 and R″13 are as defined above for R13; —NR14R15 or —N⊕R14R15R16 wherein R14, R15 and R16 are each independently of the other(s) hydrogen or unsubstituted or substituted C1-C18alkyl or aryl, or R14 and R15 together with the nitrogen atom bonding them form an unsubstituted or substituted 5-, 6- or 7-membered ring which may optionally contain further hetero atoms;
