Abstract

1436448 Disazo pigments SANDOZ Ltd 9 Oct 1973 [13 Oct 1972] 47035/73 Heading C4P Novel disazo pigments of Formula I where each X, R 1 and R 2 is independently F, Cl or Br may be prepared (a) by condensing a compound of Formula II where R 3 is -COOH or a functional derivative thereof with a suitable 2,5-dihaloparaphenylenediamine or (b) by coupling a diazotized 2-halo-5- trifluoromethylaniline with a compound of Formula V The pigments of Formula I give red or bluishred shades when used for mass pigmentation of PVC and may also be used to mass pigment other synthetic polymeric materials, to colour surface coating materials, printing inks and viscose and cellulose acetate spinning solutions, for dyeing paper prior to sheet formation and for printing and coating textiles. The monoazo intermediate 1 - (2 - chloro - 5 - trifluoromethylphenylazo) - 2 - hydroxy - 3 - naphthoic acid is prepared by azo coupling.
