DEFINITION

Classification: 523/136

Composition sensitive to or resistant to radioactive material or cathode rays (e.g., electron bombardment, etc.) or process of preparing:

(under subclass 1) Subject matter wherein a composition which is resistant to, yet does not absorb radioactive materials or cathode rays is claimed or solely disclosed or to processes of preparation thereof.

(1) Note. For an explanation of patent placement referring to claimed or solely disclosed, see (in the class definition) the section of SEARCH THIS CLASS, SUBCLASS that refers to this subclass.

(2) Note. A composition which is not solely disclosed as being resistant to radioactive materials or cathode rays is placed as appropriate in Classes 523 and 524 hereinbelow.

250, Radiant Energy,

515.1, for methods of using and apparatus for X-ray shields which absorb energy propagated in the form of electromagnetic waves or traveling subatomic, atomic, or molecular particles.

252, Compositions, for special use compositions of that class

containing a synthetic resin and see in particular 582, 589 for compositions specialized for use as optical filters including those which filter ray energy outside the visible spectrum, such as ultraviolet, infrared, or X-rays; subclasses 301.16+, especially subclass 301.35 for optical brighteners or organic luminescent compositions containing a synthetic resin; subclass 478 for shielding compositions which may contain a synthetic resin designed to prevent the passage of X-ray radiation and alpha, beta, or gamma rays and other energy sources which are released in nuclear transformation; and subclasses 600+ for compositions which do not contain a synthetic resin but are responsive to radiation.

424, Drug, Bio-Affecting and Body Treating Compositions,

4+, for a X-ray contrast composition; and subclasses 59+ for a sun or radiation screening composition to be applied to a living body, such as sun lotion.

427, Coating Processes,

160, for coating processes wherein the coating has X-ray properties.

430, Radiation Imagery Chemistry: Process, Composition, or Product Thereof, appropriate subclasses, and see in particular

269+, and 495.1+ for compositions which are affected by radiation to form an image and for processes of making images from compositions affected by radiation, and the resultant products thereof.
