Conductive polymer composition, substrate, and method for producing substrate

A conductive polymer composition which comprises:

• a composite comprising
• a π-conjugated polymer (A), and
• a polymer (B) shown by the following general formula (1);
• H2O (D) for dispersing the composite;
• and
• a water-soluble organic solvent (C), wherein the component (C) comprises an organic solvent (C1) having a boiling point of 120° C. or more and an organic solvent (C2) having a boiling point of less than 120° C. such that 1.0 wt % ≤(C1)+ (C2)≤50.0 wt % is satisfied relative to a total of the components (A), (B), and (D),
• wherein R1 represents a hydrogen atom or a methyl group;
• Z represents any of a phenylene group, a naphthylene group, an ester group, an ether group, an amino group, and an amide group;
• when Z is a phenylene group or a naphthylene group, R2 represents any of a single bond and a linear, branched, or cyclic hydrocarbon group having 1 to 12 carbon atoms optionally having one or both of an ester group and an ether group;
• when Z is an ester group, an ether group, an amino group, or an amide group, R2 represents any of a single bond and a linear, branched, or cyclic hydrocarbon group having 1 to 14 carbon atoms optionally having an ether group;
• “m” represents any one of 1 to 3;
• R3 and R5 each independently represent a hydrogen atom or a methyl group;
• R4 independently represents any of a single bond and a linear, branched, or cyclic hydrocarbon group having 1 to 12 carbon atoms optionally having one or both of an ether group and an ester group;
• X3 represents any of a single bond, a methylene group, an ethylidene group, an isopropylidene group, an ether group, an ester group, an amino group, an amide group, and a linear, branched, or cyclic hydrocarbon group having 1 to 12 carbon atoms optionally containing an ether group, an ester group, an amino group, an amide group, or a heteroatom, and the amino groups and the amide groups optionally contain any of a hydrogen atom and a linear, branched, or cyclic hydrocarbon group having 1 to 12 carbon atoms optionally containing a heteroatom;
• X1 and X2 each independently represent any of a single bond, a phenylene group, a naphthylene group, an ether group, an ester group, an amide group, and a linear, branched, or cyclic hydrocarbon group having 1 to 13 carbon atoms optionally having one or both of an ether group and an ester group;
• Rf1 and Rf2 each represent a linear or branched alkyl group having 1 to 4 carbon atoms with at least one or more fluorine atoms, or a phenyl group substituted with a fluorine atom and/or a trifluoromethyl group;
• and “a”, b1, and b2 satisfy 0<a<1.0, 0≤b1<1.0, 0≤b2<1.0, and 0<b1+b2<1.0.
