(1) Note. The meaning to be given to the various "art" terms appearing in this class, but which have not been included in the Glossary below, is the same as that generally accepted or in common usage. However, certain terms employed in this class, which are included below, have been assigned definitions tailored to meet the needs of this class and therefore those may be more restricted or less limited or even altogether different from those in common usage.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

A. COMPOUND, COMPOSITION, AND MATERIAL CLASSES.

2. Composition or Material

a. The rules for determining Class placement of the Original Reference (OR) for claimed chemical compositions are set forth in the Class Definition of Class 252 in the section LINES WITH OTHER CLASSES AND WITHIN THIS CLASS, subsection COMPOSITION CLASS SUPERIORITY, which includes a hierarchical ORDER OF SUPERIORITY FOR COMPOSITION CLASSES.

b. A composition disclosed for forming an image by a Class 430 process as one of plural uses but is not claimed as having a Class 430 imaging use is placed as an original in another class based on its general utility and crossed to Class 430. See References to Other Classes below, for related art areas: chemistry: electrical and wave energy; compositions; and synthetic resin classes

c. A composition which is not an imaging composition but which is disclosed or claimed as useful as a part of a Class 430 product is classified in Class 430 only when claimed in conjunction with a Class 430, imaging composition or layer. Otherwise such composition, per se, is classified on some other basis depending on its ingredients or function. See References to Other classes, below for related art areas: specialized metallurgical process; compositions, coating or plastic; compositions; synthetic resins or natural rubbers; organic coupounds.

d. A composition solely disclosed or claimed for radiation imagery is classified in Class 430.

e. For a general search of Composition or Material classes, see References to Other Classes, below.

B. LINES WITH AND SEARCH NOTES TO ARTICLES OR PRODUCT CLASSES.

2. Class 430, Radiation Imagery Chemistry: Process, Compositions, or Product Thereof, provides for a product (article) which is (a) imaged and defined by its composition, (b) radiation sensitive and limited by claims or disclosure for use in radiation imagery, and (c) products of radiation imagery not elsewhere classified.

3. An article or product defined by section 2 combined with significant structure for another class will be classified in the class providing for the structure and crossed to Class 430.

4. Cases involving multiple claimed subject matter, i.e., claims for both Class 430 and class(es) mentioned in section 3 will be classified in Class 430 and crossed to the other class(es). See References to Other Classes, below.

C. LINES WITH AND SEARCH NOTES TO PROCESS AND APPARATUS CLASSES.

1. General Relation With Process And Apparatus Classes.

Class 430, Radiation Imagery Chemistry: Process, Composition, or Product Thereof, is the residual class for forming an image by use of radiation or finishing such image by post imaging treatment, and the process of making a composition or product solely disclosed or claimed for use in radiation imagery.

Also see References to Other Classes, below.

2. Relation With Special Classes Involving Radiation Imagery.
