PRETREATMENT PROCESS OF ELECTROLESS PLATING MATERIAL

摘要

PROBLEM TO BE SOLVED: To form a plated film showing an excellent adhesion, without subjecting a resin material to surface roughening. SOLUTION: The resin material having an unsaturated bond is brought into contact with an ozone-containing solution to perform ozone treatment. The surface of the ozone-treated resin material is stabilized through stabilizing treatment and subsequently subjected to electroless plating. It is considered that the stabilizing treatment decomposes unstable ozonides at the surface of the resin material and generates methylol or carbonyl groups. Therefore, the plated film exerts a high adhesion immediately after electroless plating. COPYRIGHT: (C)2003,JPO
