DEFINITION

Classification: 514/515

With an additional active ingredient:

(under subclass 514) Subject matter wherein the organic active ingredient contains a compound having the group -CNX or -XCN and an additional organic active ingredient.

(1) Note. Synergistic and potentiating agents are considered active ingredients.

(2) Note. The starting solid polymer may be subjected to a number of aftertreating steps the sequence or numbers of which will not affect classification. The important criteria is that every reaction be considered proceeding from the starting solid polymer to the final product. This is consistent with the classification rules set out in the Class 520 Series.
