Abstract
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 (SR ) having a value which is higher than 10 &OHgr;/□, or more preferably higher than 10 &OHgr;/□. By heating selected areas of the polymer layer, the surface resistivity of these areas is reduced to SR /&Dgr; wherein &Dgr; is at least 10, preferably at least 10 and more preferable at least 10 . The electroconductive pattern thus obtained can be used as an electronic circuit for making an electric or semiconductor device such as a printed circuit board, an integrated circuit, a display, an electroluminescent device or a photovoltaic cell.
