<p>1. Water-soluble monoazo compounds of the general Formula (1) see diagramm : EP0072557,P22,F3 in which D is a group of the Formula (2a) or (2b) see diagramm : EP0072557,P22,F4 see diagramm : EP0072557,P22,F5 in which M is a hydrogen atom or the equivalent of a monovalent, divalent or trivalent metal ; R**1 is a hydrogen atom, an alkyl group of 1 to 4 C-atoms, an alkoxy group of 1 to 4 C-atoms or a chlorine atom ; R**2 is a hydrogen atom, an alkyl group of 1 to 4 C-atoms or an alkoxy group of 1 to 4 C-atoms, the formula radicals R**1 and R**2 can have meanings which are identical to one another or different from one another, R is the methyl group, a carboxy group or a carbalkoxy group of 2 to 5 C-atoms, K is a phenyl radical or naphthyl radical, both of which can be substituted by 1, 2 or 3 substituents from the group consisting of sulfo, carboxy, sulfamoyl, carbamoyl, alkyl of 1 to 4 C-atoms, alkoxy of 1 to 4 C-atoms and chlorine, and optionally by a group of the formula -SO2 -Z in which Z represents the beta-hydroxyethyl group or a group Y of the meaning given below, Y is the vinyl group or an ethyl group containing in the beta-position a radical which can be eliminated as an anion under alkaline conditions, p represents the number zero or 1, but is mandatorily 1 if the formula radical K is not substituted by the group -SO2 -Y.</p> |
