摘要： The present invention relates to a process for obtaining a multilayer composition, to a composition obtainable via such method and to an article comprising said composition. The process comprises at least the following: i. providing a polymeric layer (L1) comprising an aromatic polymer selected from the group consisting of poly(aryl ether sulfone) polymer (P1) and a polyarylene sulphide (P2), and having at least one surface (S1); ii. treating at least the surface (S1) of (L1) with a radio-frequency glow discharge process in the presence of an etching gas medium comprising a nitrogen-containing gas to obtained an etched surface (52); iii. optionally, contacting the etched surface (S2) obtained in step ii. with a composition (LC3) comprising a surfactant to obtain at least a pre-treated surface (S2a); iv. contacting the etched surface (S2) obtained in step ii. or the pre-treated surface (S2a) obtained in step iii. with a liquid composition (LC1) comprising at least a metal (MC) in ionic form and having a pH not less than 9.0, so as to provide an article having at least one surface (S-3) treated with a composition containing metal (MC) in ionic form; v. reducing metal (MC) in ionic form on (S-3) to its metallic form by contacting (S-3) with a liquid composition (LC2) containing a reducing agent; vi. forming by electroless deposition a layer (L2) onto the at least one treated surface obtained in step v., said layer (L2) comprising at least one metal compound (M1) and metal (MC) in ionic form; vii. applying an additional layer (L3) comprising a metal (M2), equal to or different from (M1), directly on layer (L2); and, optionally, viii. applying an additional layer (L4) of a metal (M2) on (L3).
