In this subclass, it is desirable to add the indexing codes relating to ingredients of compositions classified in the mixture groups of groups C 11 D 1/00 to C 11 D 10/00. The indexing codes, which are chosen from groups C 11 D 1/00 to C 11 D 9/00, with the exception of groups C 11 D 1/37, C 11 D 1/645 to C 11 D 1/655, C 11 D 1/825 to C 11 D 1/86, C 11 D 1/94, C 11 D 3/065 to C 11 D 3/075, C 11 D 7/56, C 11 D 7/60 and
C 11 D 9/60, have the same numbers as the classification symbols, but a colon is used instead of the oblique stroke, and should be linked. |
