Abstract

The invention comprises asymmetrical dyes of the formula <FORM:0961465/C4-C5/1> and their salts, where Ar is an aryl group not having an arylamino substituent in the 4-position, R1 is an optionally substituted alkyl, aryl, aralkyl, alkaryl or heterocyclic group other than -R2SO3H and R2 is an arylene group bound to the nitrogen atom directly and to the sulphonic acid group either directly or through an amino-sulphonylphenyl or an oxyalkyl radical, provided that when R2 is p-phenylene, R1 and Ar are not both phenyl. The dyes are made by reacting at an elevated temperature a dye of the formula <FORM:0961465/C4-C5/2> where Ar and R2 are as above and R3 is an alkoxy group, with an amine of the formula R1-NH2, where R1 is as above, preferably in the presence of benzoic acid. The dyes are blue to green to greenish-yellow shades. Specification 961,466 is referred to.
