Title:
PLATING CATALYST AND METHOD
Document Type and Number:
Japanese Patent JP2013155437
Kind Code:
A
Abstract:
To provide a colloidal catalyst system simultaneously attaining bath stability, adsorption ability, and the balance of catalytic activity.
A solution containing noble metal ions and a polymer having a carboxyl group and a nitrogen atom is prepared, and a reducing agent is added to the solution while stirring the solution, and thus, a catalyst solution containing the polymer having the carboxyl group and the nitrogen atom and noble metal nanoparticles is produced. This invention is useful for electroless plating metal on a non-conductive surface without an acceleration process.
