摘要

Monoazo dyes of formula D-N=N-K-NR3-Y-COOR (I) are new: D = diazo component: K = (II)-(IV) R = CHR4.COOR5, CH2CF3 or CH2CF2CF2H; R6 = H or OH; R1 = H, Cl, 1-4C alkyl or alkoxy, or acylamino; R2 = H, 1-4C alkoxy, 1-4c alkoxyethoxy, Cl or Br; R3 = H; 1-6C alkyl; 3-4C alkenyl (opt. substd. by Cl or Br); 3-4C alkynyl; 1-4C alkyl substd. by phenyl, 1-4C alkoxycarbonyl, 3-4C alkenyl- or alkynyloxy-carbonyl; phenoxy (2-4C) alkyl; CH2CHR8.CH2R9; or 2-4C alkyl substd. by 1-3 of halo, CN, 1-4C alkoxy, 1-4C alkylcarbonyloxy or 1-4C alkoxycarbonyloxy, R2 and R3 may together be asterisk CHMe.CH2CMe2 with the atom marked asterisk attached to K1; R4 = H, phenyl or 1-4C alkyl; R5 = phenyl (opt. substd. by 1-3 of 1-4C alkyl, alkoxy or alkoxycarbonyl or halo, or by one of CHO, CN, thiocyanato, phenyl, benzyloxy, 1-4C alkoxycarbonyl (1-2C) alkoxy, 1-4C alkylcarbonylamino, 1-4C alkylcarbonyloxy or NO2); 1- or 2- naphthyl, phenyl (1-4C) alkyl or 1-phenyl-propen-3-yl (in the last 2 opt. ring substd. by 1 or 2 halo, 1-4C alkyl or alkoxy, or by one NO2 or 1-4C alkoxycarbonyl); or R5 = (halo)allyl, methallyl, propargyl, tetrahydrofuryl-2-methyl, tetrahydropyranyl-2-methyl, 2-4C chloroalkyl, 2-4C bromoalkyl or (VI); R7 = H or 1-4C alkyl; R8 = OH, 1-4C alkyl- or alkoxy-carbonyloxy; R9 = Cl, 1-4C alkoxy, phenoxy, allyloxy or 1-4C alkylcarbonyloxy; R10 = H or 1-4C alkyl; R11 = H, halo, 1-4C alkyl or alkoxy, or NO2; Y = 2-3C alkylene; n = 0 or 1; when K is other than K1, R3 is H; mixts. of (I) are included.D is of the phenyl, thienyl, (benz) thiazolyl, (benz) isothiazolyl, thiadiazolyl, pyrazolyl, imidazolyl or triazolyl series; K = K1.
