Abstract: Shaped structures such as fibres, flocks, fabrics, felts or foils, of linear aromatic polyesters are dyed or printed with a dyestuff of the formula:- in which X represents a halogen atom or an alkyl, alkoxy, aryl or cyano group and n one of the numbers 0, 1 or 2, at least one n being other than zero. Dyeing or padding may be effected at 80 DEG -100 DEG C. in the presence of carriers such as benzoic acid, o-hydroxybenzoic acid or their methyl esters, or diphenyl or its 2- or 4-hydroxy derivatives. Dyeing may also be effected at temperatures above 100 DEG C. under pressure. Prints are subsequently heated or steamed. Numerous examples are given. The dyestuffs are made by condensing phthalic acid or its anhydride, amide or imide with 2-methyl-3-hydroxy-quinoline and subsequently introducing the halogen atoms or the above specified groups into the condensate. Alternatively, one or both constituents of the condensation product may contain the halogen atoms or the above specified groups prior to condensation.
