Abstract
1289638 Monoazo dyes CIBA-GEIGY AG 30 Jan 1970 [13 Feb 1969] 4726/70 Heading C4P [Also in Division G2] Monoazo dyes have the general formula wherein G denotes a naphthalene residue which in the 1-position contains an azo group, in the 2-position contains an optionally substituted phenylamino group and in the 8-position contains an OH group, as well as at least one sulphonic acid or sulphonic acid amide group; E denotes a mono- or bi-cyclic aromatic residue which contains at most 2 sulphonic acid groups or sulphonic acid amide groups, such that the residues G and E together contain 1-4 sulphonic acid or amide groups; M denotes a phthalic acid imide residue bonded to E via the imide nitrogen atom or denotes a residue of formula -NH-X-D bonded via the nitrogen atom, each of X and Y independently denote a residue -CO- or -CONH-, with the nitrogen atom being bonded to D or Q; each of D and Q denotes a mono- or bi-cyclic aromatic residue; Z denotes a residue of formula -CO- or -CONH- with the nitrogen atom bonded to A or an -SO 2 – residue; A denotes an unsubstituted aliphatic residue or an optionally substituted aromatic or heterocyclic residue and m and n each denote 1 or 2. The dyes may be prepared by reacting a compound of formula G-N = N-E-(M-) m-1 (NH-Y-Q) n-1 (NH 2 with a compound of formula A-T where T is a -OCN, -CO-Hal or -SO 2 -Hal where Hal is a halogen atom or with the anhydride of an aliphatic or aromatic mono- or di-carboxylic acid. The dyes are used as image dyestuffs for the silver dyestuff bleaching process.
