DEFINITION

Classification: 427/255.31

Metal and chalcogen containing coating (e.g. metal oxide, metal sulfide, metal telluride, etc.):

(under subclass 255.29) Process wherein the coating includes chalcogen and metal.

(1) Note. Metal compounds containing chalcogen are proper for placement in this subclass.
