FIELD: electroplating, possibly application of gloss silver coating out of cyan free electrolytes.
SUBSTANCE: electrolyte contains soluble compound of silver, comlexing agent 5,5 - dimethylhydantoin, electrically conducting salt of alkali metal, alkali reagent, glossing additive 3 -pyridinesulphonic acid, depassivating additive N - alkylpyrrolidon having 2 - 5 C atoms in alkyl radical. Coating is applied from aqueous solution of electrolyte with pH 9.5 - 11.5.
EFFECT: possibility for applying stable high quality mirror coating during long period of electrolyte operation while using soluble silver anode.
