DEFINITION

Classification: 526/120

(under subclass 90) Subject matter wherein (1) the specified material contains a transition metal compound which is in admixture with a compound containing a heavy metal atom and which heavy metal is other than a heavy metal atom directly bonded to a carbon atom or to a hydrogen atom; or (2) wherein a transition metal containing compound additionally contains at least one heavy metal atom in the same molecule, which heavy metal atom is not directly bonded to a hydrogen or carbon atom (e.g., mercuric tungstate, or a mixture of NiCl₂ and ZnCl_{2[end subscrpt], etc.).}
