Patent number: 6444400Abstract: A method of making an electroconductive pattern on a support is disclosed. The support is provided with a polymer layer containing a polythiophene, a polyanion and a di- or polyhydroxy organic compound. Said layer is characterized by an initial surface resistivity (SRi) having a value which is higher than 104 &OHgr;/□, or more preferably higher than 106 &OHgr;/□.
