DEFINITION
Classification: 252/301.4
INORGANIC LUMINESCENT COMPOSITIONS:
(under the class definition) Compositions which are constituted entirely of inorganic material and contain a component having the property of emitting light or analogous rays as a result of irradiation by wave energy radiated by some other source.
(1) Note. This and the indented subclasses also include compositions in the preparation of which a temporary organic vehicle, binder or adjuvant is employed and which is removed or destroyed in the course thereof.
