Reaction Steps

Proceeding in a manner analogous to Example 5 but replacing for the ground dyeing the 12 parts of dyestuff C.I. Acid Green 106 by a mixture of 2.2 parts of dyestuff C.I. Acid Brown 298, 0.7 parts of dyestuff C.I. Acid Green 106 and 8.24 parts of dyestuff C.I. Acid Blue 80 (K'pH6 -value=9), and for the local printing the mixture of C.I. Acid Yellow 151, C.I. Acid Yellow 127 and C.I. Acid Orange 127 by a mixture of 2 parts of dyestuff C.I. Acid Orange 156 (K'pH6 -value=2.5) and 0.4 parts of dyestuff C.I. Acid Blue 40 (K'pH6 -value=2), similar good results are obtained.
