Patent ID: 7147936

Claim:
A layer configuration on a support, said layer configuration comprising a layer containing a polymer containing optionally substituted 3,4-alkylenedioxythiophene structural units, in which said 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 2 —CH(OH)—(CH 2 ) m —S—CH 2 —C(R 1 )(R 2 )—CH 2 —S—(CH 2 ) n —CH(OH)—CH 2 —OH (I) wherein R 1 and R 2 are independently H, —OH or alkyl, and n and m are independently 1, 2 or 3; compounds according to formula (II): HO—(CH 2 ) p —S—CH 2 —S—(CH 2 ) q —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.
