Abstract

The invention comprises disperse dyestuffs having the general formula <FORM:1037377/C4-C5/1> wherein R denotes an alkyl, aryl or cycloalkyl group which may contain substituents other than sulpho groups and carboxyl groups; and Ar is either a benzene nucleus, which may contain substituents as above, the nitrogen atoms being linked to two adjacent carbons of the benzene nucleus, or a naphthalene nucleus which may be substituted as above, the nitrogen atoms being linked to two carbon atoms of the naphthalene nucleus in ortho or peri relationship. The novel dyestuffs may be made by heating a compound of formula <FORM:1037377/C4-C5/2> wherein X denotes a halogen atom, or sulphogroup or an alkali metal salt thereof with a compound ROH in the presence of a base, preferably in a temperature range of 60-150 DEG C.
