DEFINITION

Classification: 522/11

Contains compound containing keto group not part of a ring and nonspecified rate-affecting material other than mere photoinitiator or photosensitzer:

(under subclass 7) Subject matter wherein one rate-affecting material containing at least one organic keto group not part of a ring, as below at the end of this definition, and the other rate-affecting material is one wherein none of the chemical atoms can be deduced from the claim with certainty and wherein the rate-affecting material which is not chemically stated is other than a photoinitiator or phtosensitizer.

(1) Note. A material having a keto group as part of a ring may still be proper for this subclass if in fact an additional keto group is present which is not part of a ring, e.g., as shown in the second illustration, above.

(2) Note. Ring as used in this subclass includes heterocyclic rings.

(3) Note. See Class 520, the Glossary, for a definition of the term "Ketone".

8+, for a system containing a specified rate-affecting material containing at least one keto group not part of a ring in combination with a rate-affecting material designated merely as a "photoinitiator" or "photosensitizer".
