X for Hor an optionally substituted alkyl group; m and n are each 0 or 1, and the sum of m and. n is at least 1'; rings A, B and D may each bear one or more further substituents and the molecule is free from sulphonic acid groups. These compounds may be obtained by condensing 1 mole of a compound of formula where Hal is Cl or Br with I mole of an amine of formula and 1 mole of'an amine of formula</p> |
