DEFINITION

Classification: 430/495.1

Radiation sensitive product:

(under the class definition) Compositions or elements which are affected by radiation to form an image. An element is a complete self-sustaining product which can be mechanically handled and is in a state ready to be used in an imaging apparatus to produce an image by a process of this class.

(1) Note. An element may be classified in an appropriate composition subclass if no previously appearing subclass is proper.

516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting,

9+, for continuous liquid phase colloid systems (e.g., foams, emulsions, suspensions, dispersions); subclasses 98+ for colloid systems of continuous or semicontinuous solid phase with discontinuous liquid phase (gels, pastes, flocs, coagulates) or agents for such systems or making or stabilizing such systems or agents; in each instance, when generically claimed or when there is no hierarchically superior provision in the USPC for the specifically claimed art.

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

136, for a composition containing a synthetic resin which is resistant to, yet does not absorb, radioactive materials or cathode rays or to processes of preparing said composition.
