Abstract
Azo dyes are produced in substance, on the fibre, or in the form of lakes, from diazotized alkyl-, aryl-, or aralkyl-amides of an alkyloxy-m-amidobenzoic acid and arylamides of 2 : 3-oxynapthoic acid. The products are red and the process can be used for the production of alizarin pink shades. Examples are given in which diazotized m-amido-p-methoxy-benzoic anilide is coupled with 2 : 3-oxynaphthoic-o-toluidide, and in which the same diazo compound is coupled with the 5-chlor-2-toluidide in presence of barium sulphate. Pink shades are produced on the fibre by impregnating with 2 : 3-oxynaphthoic-o-toluidide, or 4-chlor-2-anisidide, and dyeing or printing with diazotized m-amido-p-methoxybenzoic anilide. Other diazo components, substituted in the acid amide substituent, may be used. Specifications 6379/12 and 17279/13, [Class 15 (ii), Dyeing, Processes &c. for], are referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of substituted amides of aryloxy- or aralkyloxy-m-amido-benzoic acids as diazo components; this subject-matter does not appear in the Specification as accepted. Alkyl-, aryl-, or aralkylamides of alkyloxy-m-amidobenzoic acids are obtained by converting a m-nitro-alkyloxybenzoic acid into the acid chloride and condensing with primary or secondary amines.ALSO:Azo dyes are produced on the fibre from diazotized alkyl-, aryl-, or aralkylamides of an alkyloxy-m-amidobenzoic acid and arylamides of 2 : 3-oxynapthoic acid.
