Abstract
An electroless metal plating solution is characterized by an elemental sulfur stabilizer, either in colloidal or soluble, non-ionic form. Elemental sulfur as a stabilizer is an improvement over prior art stabilizers as it can be used in substantially larger concentration than prior art divalent sulfur stabilizers which are catalytic poisons.
