DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) The dyes I (X, Y = H, Cl, Br, SO2Me, NO2, OMe; Z = NO2, SO2Me; R1 = H, Me, OMe, Cl, amido; R2 = C2-4 alkyl, optionally halogenated; R3 = C1-4 alkyl, optionally halogenated; R4 = H, OMe), useful in transfer printing on textiles, are prepd. by suitable diazotization and coupling. Thus, stirring nitrosylsulfuric acid (from 7.2 g NaNO2 and 113 g H2SO4) and 20.7 g 2,6-dichloro-4-nitroaniline [99-30-9] 2 h at 20-5.degree., adding 260 g ice, 200 mL H2O, and, over 30 min, 21.3 g N-(2-chloroethyl)-N-ethyl-m-toluidine [22564-43-8] (prepd. from the hydroxyethyl compd. and POCl3 at 90-5.degree.), neutralizing with NaOH, and heating 1 h at 90-5.degree. gives I (X, Y = Cl; Z = NO2; R1 = Me; R2 = ClCH2CH2; R3 = Et; R4 = H) [63741-10-6], dyeing polyamide and polyester fibers and cellulosics in brown shades. .
