摘要： The present invention relates to a composition comprising
i) at least one polythiophene selected from the group consisting of
- a polythiophene comprising monomer units of structure (I)

in which
*
indicates the bond to the neighboring monomer units,
X,Z
represent O or S,
R 1 -R 4
independently from each other represent a hydrogen atom or an organic residue R, with the proviso that at least one of residues R 1 to R 4 represents an organic residue R;

- a polythiophene which is characterized by its compatibility in PGME (1-methoxypropan-2-ol), demonstrated by an RF-value of at least 0.8;

iii) at least one ethylenically unsaturated compound;
iv) at least one organic solvent;
v) at least one radical initiator.
The present invention also relates to a process for preparing a layer structure, to a layer structure obtainable by this process, to a layer structure, to an electronic component and to the use of composition according to the present invention.
