The invention relates to a process for depositing a thin adhesive coating of polypyrrole on the surface of an article made of oxidizable metal, by electropolymerization of an aqueous or aqueous-alcoholic electrolytic solution of pyrrole and/or of one or more substituted pyrroles, in which the anode of the electropolymerization device consists of the article made of oxidizable metal, in which the solution contains ions selected from the ions of formula: ##STR1## in which X is selected from O, S and NH,

Process and bath for the electrolytic deposition of polypyrrole on an

The polymer films of the invention contain reactive groups and are obtained from phenols of the formula ##STR1## in which R denotes an acyl group with 1 to 7 carbon atoms, a hydroxy, carboxy, alkoxycarbonyl, amino, alkylamino or phenylamino group, and

An electroemissive component having variable emissivity is made up of a conductive substrate on which at least one continuous thin film of a solid organometallic compound has been formed by electrochemical deposition and of a conductive deposit constituted by at least one thin film and deposited on said organometallic film, the substrate and the conductive deposit being electrically connected respectively to the two poles of a variable-voltage source which controls the emissivity. The component is particularly well suited to the fabrication of electronic or optoelectronic devices such as electron tubes, luminescent cells, display panels, thin television screens, and brightness amplifiers.
