摘要

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, to 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-CH2-CH(OH)-(CH2)m-S-CH2-C(R1) (R2)-CH2-S-(CH2)n-CH(OH)-CH2-OH, wherein R1 and R2 are independently H, -OH or alkyl, and n and m are independently 1, 2 or 3; compounds according to formula (II): HO-(CH2)p-S-CH2-S-(CH2)q-OH, 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-alkylbenzimidazole compounds.
