Abstract

A process for the production of a conductive layer on a substrate, said conductive layer comprising a network of crystal needles of conductive radical cation salts based on tetrathiotetracenes, tetraselenotetracenes or tetratellurotetracenes and chlorine, bromine, iodine or copper dichloride, and said network is embedded in a polymer matrix, by coating at least one side of said substrate with a) a suspension of crystal needles of the radical cation salts of formula I in an inch solvent which may additionally contain a thermoplastic polymer or at least one starting compound for a thermosetting polymer, or b) a solution (b1) of a tetrathiotetracene, tetraselenotetracene or tetratellurotetracene, (b2) of a monomeric, oligomeric or polymeric organic compound which contains chlorine, bromine or iodone and, when heated with these tetracenes, forms a radical cation salt, or of anhydrous CuCl.sub.2, a CuCl.sub.2 aquo complex or a CuCl.sub.2 solvent complex, and (C3) of a thermoplastic polymer or at least one starting compound for a thermosetting polymer, in an inert solvent, and subsequently evaporating the solvent, which process comprises applying said layer by spraying the suspension a) …
