Zusammenfassung:Disazo compounds of formula (I) are new; in which B = a bridging group of formulae (IIa-c); R, R' = 1-4 carbon (C) alkyl, 1-4 C alkoxy, halogen or sulpho (-SO3H); R1, R1', R2, R2' = hydrogen (H) or optionally substituted 1-4C alkyl; R3 = 1-6C hydroxyalkyl; R4 = H or 1-4 C alkyl; alk = 2-12C alkylene; alk' = 2-4 C alkylene; X1, X2 = halogen, 3-carboxypyridin-1-yl or 3-carbamoylpyridin-1-yl; Y, Y' = vinyl or -CH2-CH2-U; U = a labile group; m, n = 0, 1 or 2; p, q = 0 or 1; r = 1, 2 or 3.
