| 摘要 |
Viscous aqueous electroless plating solutions comprising ionic depositable metal species such as copper or nickel, metal complexing agent such as EDTA, metal reducing agent such as formaldehyde or hypophosphite and thickener such as xantham gum, silica or carboxymethylcellulose have a viscosity greater than 50 cp, for instance up to 20,000 cp. The viscous solutions are useful for electrolessly depositing metal onto moving or inclined catalytic substrates and as a component of kits for applying electrolessly deposited metal images to such surfaces. |
