Abstract
507,274. Dyes ; dyeing. I. G. FARBENINDUSTRIE AKT.-GES. Aug. 29, 1938, No. 25310. Convention date, Aug. 30, 1937. [Classes 2 (iii) and 15 (ii)] Water-insoluble azo dyes are made in substance or on a substratum by coupling a diazo compound of an amine of the general formula with 1 - (2<1> : 3<1> - hydroxynaphthoylamino) - 4- ethoxybenzene. They yield orange shades fast to light and weather and may be used in the manufacture of lakes. In examples describing the preparation of a dye in substance and on cotton yarn, the methylsulphone is used as the diazo component; the ethyl and butylsulphones are also specified. Specifications 6379/12, [Class 2 (iii)], 17279/13, [Class 15 (ii)], and 457,687 are referred to. The Specification as open to inspection under Sect. 91 refers to the preparation of the above dyes by printing methods. This subjectmatter does not appear in the Specification as accepted.
