Zusammenfassung:	Acid disazo benzene dyes of formula (I), which contain 7-(4-amino-3-sulphophenylamino)-4-hydroxy-2-sulpho-3-naphthyl groups, are new; where A = 7-amino- or 6-acylamino-4-hydroxy-2-sulpho-3-naphthyl group of formula (IIA; Y = H) or (IIB); Ac = acetyl or propionyl or a benzoyl group, optionally substituted by methyl (Me), methoxy (OMe) or carboxyl (COOH); m, n, p, q = 0 or 1; m + p = 1; R = H or benzoyl, optionally substituted by Me, OMe or COOH; with the proviso that R is not H if m = 1, n = 0 and q = 0.
