    摘要: A mild activation process for the adhesion-activation of polyamide mouldings for electroless metallization comprises treating the substrates, successively or simultaneously, with the solution of a mixture of CaCl.sub.2, LiCl and/or MgCl.sub.2 with AlCl.sub.3, FeCl.sub.3 and/or TiCl.sub.4 in a lower alcohol and with an activator solution based on inorganic complex compounds of the formulaM.sup.n+ [E.sup.m+ Hal.sub.z.sup.- ]in whichM represents two hydrogen or alkali metal atoms or one alkaline earth metal atom,Hal represents a halogen, preferably Cl, andE represents a noble metal atom of the 1st or 8th subgroup of the periodic table, having the valency m and the coordination number z (z-m=n),or with customary colloidal or ionic systems of these noble metals.
