PURPOSE:To form a layer having superior adhesive strength and preventing blister or peeling on polyester resin by performing etching treatment for pretreating with a soln. of a heterocyclic carbonate and a soln. of a fluorine compound before plating the resin. CONSTITUTION:When a molded article of polyester resin is electroplated through a electroless plating stage, the surface to be plated is pretreated. The article is first degreased and washed by a conventional method, and it is etched. The etching is carried out by bringing the article into contact with a soln. of a heterocyclic carbonate such as heterocyclic alkylene carbonate or water a lower alcohol such as methanol or ethanol and succesively with an aqueous soln. of hydrofluoric acid, acidic ammonium fluoride or the like having 100-300g/l concn. The article is then sensitized and activated as usual, and it is electroplated through an electroplating stage. A high quality layer having superior adhesive strength can be formed by plating. |
