Abstract

1,220,304. Disazo dyes. UGINE KUHLMANN. 29 May, 1969 [30 May, 1968], No. 27275/69. Heading C4P. The invention comprises water-soluble disazo dyes of formula wherein X is H, SO 3 H or COOH, A is the residue of a 1-mono- or di-sulpho-phenyl-3-methyl-5- pyrazolone and B is the residue of a coupling component of the benzene, naphthalene, heterocyclic or N-acylacetylamino-aryl series. The dyes are prepared by the usual coupling reactions and the dyes wherein B is a resorcinol residue may be oxidized to give deeper shades. The dyes may be used to colour cotton, wool, silk and, in particular leather in orange or red shades; the oxidized dyes give brown shades on leather.
