ABSTRACT:
An effective bath for plating platinum or platinum alloys contains a complexed platinum (II) salt in which the anion component is a group or radical derived from an organic acid or inorganic acid other than a hydrohalic acid, in alkaline aqueous solution. The bath is more efficient and stable than known baths and permits good plating deposits to be achieved.
