Abstract
A layer configuration on a support, the layer configuration comprising a layer containing a polymer containing optionally substituted 3,4-alkylenedioxythiophene structural units, in which the two alkoxy groups may be the same or different or together represent an optionally substituted oxy-alkylene-oxy bridge, and a compound selected from the group consisting of polyphosphoric acids, polyphosphoric acid salts, thia-alkanedicarboxylic acids, cyclohexadiene compounds and polyhydroxy-compounds selected from the group consisting of tetronic acid derivatives; ortho-dihydroxybenzene compounds with at least one sulpho group, compounds according to formula (I):HO—CH—CH(OH)—(CH)—S—CH—C(R)(R)—CH—S—(CH)—CH(OH)—CH—OH  (I)wherein Rand Rare independently H, —OH or alkyl, and n and m are independently 1, 2 or 3; compounds according to formula (II):HO—(CH)—S—CH—S—(CH)—OH  (II)wherein p and q are independently 2, 3 or 4; compounds hydrolyzable to tetronic acid derivatives; compounds hydrolyzable to compounds according to formula (I); and sulpho-substituted 2-thia-alkyl-benzimidazole compounds.
