Process for catalyzation in electroless plating |
摘要 |
There is disclosed a novel process for catalyzation for trapping of a catalyst metal involved with the adhesion of an electroless plating to a substrate. The process is carried out by employing neither the sensitizing-activating method nor the catalyst-accelerator method. Specifically, in forming an electroless plating on the surface of a non-conductive substance as a substrate, the surface of the non-conductive substance is coated with a treatment liquid containing at least chitosan or a chitosan derivative before the steps of catalyzation and electroless plating to form a hydrophilic coating film on the surface of the non-conductive substance.
