Coating for the structured production of conductors on the surface of electrically insulating substrates

A method for producing a coated article comprising applying a layer of doped tin oxide by aerosol spray pyrolysis to an electrically insulating substrate at a surface temperature of 400.degree. C. to 600.degree. C., said layer having a thickness between 50 nm and 500 nm, and said doped tin oxide having a composition:

• Sn.sub.1-(y+z) A.sub.y B.sub.z O.sub.2
• wherein
• A represents at least one first dopant element selected from the group consisting of Sb and F, and
• B represents at least one second dopant element selected from the group consisting of In and Al, and
• wherein the proportions of the dopants satisfy the relationships:
• 0.02<y+z<0.11
• and
• 1.4<y/z<2.2.
