Abstract
1409254 Disperse monoazo dyes HOECHST AG 10 Nov 1972 [10 Nov 1971] 52052/72 Heading C4P New disperse monoazo dyes of formula wherein X is Cl or Br, R 1 is a C 1-4 alkyl group and each of R 2 and R 3 which may be the same or different is a CH 3 or C 2 H 5 group are prepared by coupling a diazotized 2,4-dinitro-6-haloaniline with an appropriate substituted aniline.
