Abstract

1455877 Magenta azo dyes and aqueous inks containing them AGFA-GEVAERT AG 28 Nov 1973 [1 Dec 1972] 55089/73 Headings C4A and C4P [Also in Division B6] Magenta dyestuffs of the formula (wherein X is alkyl or alkylamino; R 1 is H or alkyl; R 2 is H or optionally substituted alkyl; R 3 is H, alkyl or alkoxy; m is zero or 1; and n is 1 or 2) are prepared by coupling diatotized p-nitroaniline sulphonic acids with 2-amino-8- hydroxynaphthalene sulphonic acids, reducing the products and then acylating, e.g. with phosgene or isocyanates, the amines thusproduced. The are of use in the ink jet process (see Heading B6F) for which they are made up into aqueous inks optionally and preferably containing moisture-retaining agents such as hydroxyalkyl formamides and aliphatic polyols and their alkyl ethers.
