| (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. |

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; composiitions; synthetic resins or natural rubbers; organic coupounds.
d. A composition solely disclosed or claimed for radiation imagery is classified in Class 430.
