摘要： A conductive polymer dispersion including:
(a) at least one oligo- or polythiophene obtained by copolymerization of at least one monomer according to Formula I and at least one monomer according to Formula II,

wherein
A represents a substituted or unsubstituted C 1 to C 5 alkylene bridge;
R is selected from the group consisting of a linear or branched substituted or unsubstituted C 1 -C 18 -alkyl group, a substituted or unsubstituted C 5 -C 12 -cycloalkyl group, a substituted or unsubstituted C 6 -C 14 -aryl group, a substituted or unsubstituted C 7 -C 18 -aralkyl group and a hydroxyl group;
s represents an integer from 0 to 8;
Ra and Rb are independently from each other selected from the group consisting of hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted alkaryl group and a substituted or unsubstituted aryl or heteroaryl group;

(b) a polymeric polyanion wherein at least 75 mol% of the monomeric units of the polymeric polyanion are functionalized with a functional group selected from the group consisting of a sulfonic acid or salt thereof, a phosphonic acid or salt thereof, a phosphate ester or salt thereof, a sulfate ester or salt thereof and a carboxylic acid or salt thereof,
characterized in that a weight ratio of the monomer according to Formula I to the monomer according to Formula II is from 75/25 to 25/75.
