Abstract
The invention comprises yellow vat dyestuffs of the formula:- <FORM:0867160/IV(c)/1> in which one or more halogen atoms or alkoxy groups may be present in the 3-, 4-, 31- or 41-position and A is a phenylene radical which may be substituted by one or more halogen atoms. The invention further comprises a process for making the dyestuffs by heating together 2 to 2,2 mols of one or more 1 : 2-diaminoanthraquinones which may have one or more halogen atoms or alkoxy groups in the 3- and/or 4-position with one mol of a compound of the formula X1-A-X2 where X1 and X2 each represents a <FORM:0867160/IV(c)/2> group (Y being a chlorine or a bromine atom and R being an alkyl, aralkyl or aryl radical) and where A has the meaning given above. The dyestuffs colour natural or regenerated cellulose and linear polyamides.
