Abstract:
1. Solution for activating the surface of a substrate for the purpose of its subsequent covering with a metal layer deposited via an electroless route, said surface consisting exclusively of a polymer or comprising at least one area formed from a polymer and at least one area formed from an oxide, wherein the solution comprises: A) an activator formed from one or more palladium complex(es) selected from the group consisting of: palladium complexes of formula (I) in which: R1 and R2 are identical and represent H; CH or R1 represents H and R2 represents CH 2 CH 2 NH 2 ; or R1 represents CH 2 CH 2 NH 2 and R2 represents CH 2 CH 2 NHCH 2 CH 2 NH 2 ; or R1 represents H and R2 represents CH 2 CH 2 NHCH 2 CH 2 NHCH 2 CH 2 NH 2 ; X represents a ligand selected from the group consisting of Cl palladium complexes of formula IIa or IIb in which: R1 and R2 are as defined above and Y represents a counterion comprising two negative charges formed: B) a binder formed from one or more organic compounds selected from the group consisting of compounds comprising at least two glycidyl functions and compounds comprising at least two isocyanate functions; and C) a solvent system formed from one or more solvents capable of dissolving said activator and said binder.
