摘要

Reactive azo dyes of formula (I), their salts and/or mixts. are new. In (I) R = H or 1-4C opt. substd. alkyl, a = 0 or 1; Z = Z1-Z4, Hal = F or Cl. In (II)-(VII) (left-hand N bound to triazine); m = zero or 1; B1 = 2-4C alkylene, (2-3C) alkylene-Q-(2-3C) alkylene, 3-4C alkylene monosubstd. by OH or (VIII) (joined either way round); Q = O or NR; R1 = H, 1-4C alkyl or alkoxy, COOH or SO3H; D=D1 = (IX), (X); X2 = (XI) or (XII); D3 = (XIII) or (XIV) each of R2 and R3 = H, halo, 1-4C alkyl or alkoxy, COOH or SO3H; R4 = 1-4C alkyl or alkoxy, OH, COOH or acetamido; p = 0-2 and q = 0 or 1, with p+q = 1 or 2; r = 0-2 and t= 0 or 1 with r+t = 1-3; b = 0 or 1; Zb = (XV); X = H, Cl or CN; Y (both the same) = F or Cl.
