  • Patent number: 10975474
    Abstract: A process for depositing metal or metal alloy on a substrate including treating the substrate surface with an activation solution comprising a source of metal ions so the metal ions are adsorbed on the substrate surface, treating the obtained substrate surface with a treatment solution containing an additive selected from thiols, thioethers, disulphides and sulphur containing heterocycles, and a reducing agent suitable to reduce the metal ions adsorbed on the substrate surface selected from boron based reducing agents, hypophosphite ions, hydrazine and hydrazine derivatives, ascorbic acid, iso-ascorbic acid, sources of formaldehyde, glyoxylic acid, sources of glyoxylic acid, glycolic acid, formic acid, sugars, and salts of aforementioned acids; and subsequently treating the substrate surface with a metallizing solution comprising a source of metal ions to be deposited such that a metal or metal alloy is deposited thereon.
