Title

Titles differ between systems:

IPC: containing acid groups, e.g. —COOH, —SOH, —POH, —OSOH, —OPOH; Salts thereof

CPC: containing acid groups, e.g. —CO2H, —SO3H, —PO3H2, —OSO3H, —OPO2H2; Salts thereof

Full titles differ between systems:

IPC:

Disazo or polyazo dyes of the type A → B → C, A → B → C → D, or the like, prepared by diazotising and coupling > Disazo dyes > from a coupling component "C" containing a directive hydroxy group > Phenols > containing acid groups, e.g. —COOH, —SOH, —POH, —OSOH, —OPOH; Salts thereof

CPC:

Disazo and polyazo dyes of the type A->B->C, A->B->C->D, or the like, prepared by diazotising and coupling > Disazo dyes > from a coupling component "C" containing a directive hydroxyl group > Phenols > containing acid groups, e.g. —CO2H, —SO3H, —PO3H2, —OSO3H, —OPO2H2; Salts thereof
