摘要： Adherent insoluble coating film of a phenolic resin is obtained by electrolysis of an alkaline-reacting aqueous electrolyte comprising phenol, a mono- or di-substituted phenol with substituent(s) in o- or m-position, and an alkylene diamine, in specific proportions. The current density shall never exceed 10 mA/sq.cm. The voltage is from 2.5 V to 10 V and is preferably kept constant. Coating thickness values exceeding 1 micron and up to about 25-30 microns are obtainable within a short time at the expense of 2-2.5 Faradays per mole deposited phenol. The substituted phenol is preferably o-chloro-phenol, and the diamine is preferably ethylenediamine.

摘要： Process for coating a conductive substrate used as the anode in an electrochemical cell, in which a direct electric current is passed from a cathode to the said anode through an electrolytic liquid containing a phenolic monomer in order to form a polymeric film of phenolic resin on the substrate.The electrolyte includes from 10 to 200 g/l of allylphenol or a mixture of such with other phenols, and from 5 to 200 g/l of an aliphatic amine, in solution in a mixture of water and alcohol. The polymeric film is deposited by using an electric current of a density not greater than 50 mA/cm.sup.2 of substrate, and the polymeric film so deposited is heated to a temperature of from 100.degree. to 200.degree. C. in order to induce the hardening of the said resin.
