Pre-treatment solution for catalyst application of the electroless plating, the pre-processing method using a liquid, non-electrolytic plating film, and it was prepared using a method (or) plating covering body

摘要

PROBLEM TO BE SOLVED: To provide pretreatment solution for providing catalyst for electroless plating, and a pretreatment method using the solution.;SOLUTION: The pretreatment solution comprises a silver colloidal solution containing, as essential components, at least the following components (I), (II) and (III): (I) silver colloidal particles, (II) one or two or more kinds of ions selected from ions of a metal having an electric potential capable of reducing silver ions to metal silver in the solution and/or ions oxidized at the time of reduction of the silver ions, and (III) one or two or more kinds of ions selected from hydroxycarboxylate ions, condensed phosphate ions and/or aminocarboxylate ions, the silver colloidal particles in (I) produced by the ions of the metal having an electric potential capable of reducing silver ions in (II) to metal silver. When an object to be plated is pretreated, effective catalyst for electroless plating is provided thereby.;COPYRIGHT: (C)2004,JPO&NCIPI
