Silver plating bath
lized with a light beam emitted by an extimer laser; the second step consisting of immersing the irradiated plastic piece in at least one autocatalytic bath containing metal ions and without palladium, said immersion inducing the deposit of metal ions onto the irradiated surface area to form a metal film resulting in the selective metallization of the surface; and the third step consisting of thermally processing the metallized plastic piece to induce diffusion of the deposited metal film into the polymer plastic material.
