DIFF Subgroup
C09B 33/02 Disazo dyes
Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Disazo or polyazo dyes of the types A → K ← B, A → B → K ← C, or the like, prepared by diazotising and coupling > Disazo dyes
CPC:
Disazo and polyazo dyes of the types A->K<-B, A->B->K<-C, or the like, prepared by diazotising and coupling > Disazo dyes
IPC and CPC are identically structured here. All 7 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
