Abstract
Azo dyes are made on the fibre by coupling diazotized 2-aminodiphenylsulphone with an arylide of the formula: <FORM:0392012/IV/1> in which x = alkyl or alkoxy and y = hydrogen or alkoxy or chlorine in such a manner that x and y are different from each other and y is only hydrogen when x = alkoxy. Orange shades are obtained. In an example the following coupling components are used: the o-anisidide, the 2-methoxy-4-chloranilide, the 2-methyl-4-methoxy- and 2-methyl-4-chloranilides. Specifications 6379/12, [Class 2 (iii), Dyes &c.], and 17279/13, [Class 15 (ii), Dyeing, Processes &c. for], are referred to. The Specification as open to inspection under Sect. 91 comprises also the manufacture of the above azo dyes in substance. This subject matter does not appear in the Specification as accepted.
