DEFINITION

Classification: 252/301.16

(under the class definition) Compositions which contain an organic substance having the property of emitting light or analogous rays as a result of irradiation by wave energy radiated by some other source.

(1) Note. In this subclass are placed patents directed to compositions which contain ingredients which require excitation to become fluorescent or phosphorescent.

SEE OR SEARCH THIS CLASS, SUBCLASS:

62.51+, for luminescent magnetic compositions.

301.1, for luminescent compositions containing substances which are spontaneously radioactive.

700, for chemiluminescent compositions.

SEE OR SEARCH CLASS 250, Radiant Energy,

302, for radiation tracer methods including fluorescent and phosphorescent tracer materials, subclasses 361+ for invisible radiant energy responsive signalling devices which include a fluorescent or phosphorescent detector responsive to the invisible radiation, subclass 458.1 for methods and apparatus to irradiate fluorescent and phosphorescent devices, and subclass 483.1 for fluorescent and phosphorescent devices.

260, Chemistry of Carbon Compounds, appropriate subclasses for luminescent organic compounds, per se.

313, Electric Lamp and Discharge Devices,

92, for cathode ray tubes having a fluorescent or phosphorescent screen or target, and subclasses 483+ for electric lamps and space discharge devices which include a fluorescent or phosphorescent substance as a part thereof.

362, Illumination,

84, for illuminating devices in combination with fluorescent or phosphorescent material.

427, Coating Processes,

157+, for processes of making a luminescent coating.

110+, for lubricating oils containing fluorescent ingredients.

520, Synthetic Resins or Natural Rubbers, appropriate subclasses, particularly Class 523,

161, for a composition containing a synthetic resin or natural rubber having utility as an invisible, ballpoint, or typewriter ink or to processes of preparing said composition.
