Abstract
PURPOSE: To simply obtain a pretreating liquid for increasing the adhesion between a plated layer and the surface of a substrate by adding an alkali metal hydroxide, a metal complexing agent and a reducing agent to water.
CONSTITUTION: To water are added an alkali metal hydroxide such as sodium hydroxide or potassium hydroxide, a metal complexing agent such as EDTA, its salt, tartaric acid or its salt and a reducing agent such as formalin or trioxane. The amount of the hydroxide added is adjusted to 0.5W20wt% to the total amount of the resulting treating fluid, that of the complexing agent to 1W20wt%, and that of the reducing agent to 0.1W10wt%. A substance to be plated is dipped in the fluid for a fixed time, washed, and dipped in a chemically plating bath.
