Introduced: January 1980
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 > in which the coupling component is a bis-(aceto-acetyl amide) or a bis-(benzoyl-acetylamide)
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 > in which the coupling component is a bis-(aceto-acetyl amide) or a bis-(benzoyl-acetylamide)
No child classifications to compare. This is a leaf node in both IPC and CPC.
