<p>A composition (C1) comprises at least one polythiophene (a) containing recurring units; at least one polymer (b) that is different from (a) and which contains sulfonate salt or carboxylate salt; and at least one polymer (c) that is different than (a) and (b) and which contains sulfonate salt or carboxylate salt and is selected from partially fluorinated polymer and/or perfluorinated polymer. A composition (C1) comprises at least one polythiophene (a) containing recurring units of formula (I); at least one polymer (b) that is different from (a) and which contains SO 3 ->M +> or COO ->M +>; and at least one polymer (c) that is different than (a) and (b) and which contains SO 3 ->M +> or COO ->M +> and is selected from partially fluorinated polymer and/or perfluorinated polymer. A : optionally substituted 1-5C alkylene; R : linear or branched 1-18C alkyl, 5-12C cycloalkyl, 6-14C aryl, 7-18C aralkyl, 1-4C hydroxyalkyl or hydroxyl; x : 0 - 8;and M : H, Li, Na, K, Rb, Cs or NH 4. An independent claim is included for an electroluminescent (EL) arrangement comprising either at least one layer selected from hole-injecting layer and hole-transporting layer where hole-injecting layer and hole-transporting layers each containing (C1); or a substrate, at least two electrode layers, at least one emitter layer and at least one hole-injecting layer where at least one electrode layer abuts the substrate, the emitter layer is interposed between two electrode layers and at least one hole-injecting layer is interposed between one of the electrode layers and the emitter layer and further the hole-injecting layer containing (C1).
