Abstract
519,644. Dyes. I. G. FARBENINDUSTRIE AKT.-GES. Sept. 26, 1938, No. 28040. Convention date, Sept.,27 1937. [Classes 2 (iii) and 15 (ii)] Polyazodyes' are made by coupling a diazotized acidyldiamine or nitroamine of the benzene series or a derivative or sulphonic acid thereof with a 1-amino-2-alkoxynaphthalene or a sulphonic acid, thereof, further diazotizing the aminoazo dye thus obtained, coupling with an aminobenzoylated J acid, diazotizing, coupling with resorcinal and converting the acidylamino group or the nitro group into, the amino group. They yield clear green dyeings on cotton which may be after treated with formaldehyde. In examples the following dyes are described : 1-amino-4- oxalylaminobenzene - 3 - sulphonic acid# 1-amino - 2 - ethoxynaphthalene # 2 - (31- or 41 - aminobenzoylamino) - 5 - naphthol - 7 - sulphonic acid or 2-(3<11>-aminobenzoyl-3<1>-aminobenzoylannno) - 5 naphthol - 7 - sulphonic acid or the corresponding p-m- or p-p aminobenzoylaminobenzoyl compounds# resorcinol, the oxalylamino group being saponified to the amino group by means of caustic soda. The Specification as open to inspection under Sect. 91 comprises the use of any acidyldiamine or nitroamine as first component.. This subjectmatter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to German Specification 276,140.
