Abstract

551,434. Dyes and dyeing ; artificial silk : cellulose derivative compositions. ARGYLE, C. S. July 23, 1941, No. 9299. [Classes 2 (ii), (iii) and 15 (ii)] Azo dyes are obtained by coupling a diazotized 2-aminothiazole with . a mono-acidvl-mphenylenediamine. Specified diazo components are 4-methyl-2-aminothiazole, 2-amino-benzthiazole and its 6-methyl, 6-methoxy, 6- ethoxy, 6-chloro, 6-acetylamino and 6-benzoylamino derivatives and 2-amino-4:5-benzobenzthiazole, and specified coupling components are m-amino-acetamilide and its N- diethyl, N-di-(#-hydroxyethyl) and N-ethyl-N- #-hydroxyethyl derivatives, N-dimethyl-maminopropionanilide, 3-dietliylamino-4-methylacetanilide, 3-diethylamino-4-methoxy-acetanilide, N-diethyl-m-amino-stearanilide and N- diethyl-m-amino-benzanilide. The products give dischargable brilliant red shades on cellulose ester or ether materials and are applicable also for colouring synthetic linear superpolyamide materials. They may also be incorporated in cellulose ester or ether lacquers or spinning solutions. The dyestuffs containing diazotizable amino groups may be diazotized upon the materials and developed, e.g. with N-diethylaniline, N-di-(#-hydroxyethyl)-m-toluidine, N-diethyl-m-amino acetanilide or N-ethyl-1-naphthylamine. Examples relate to the production of the dyestuffs, (1) 2-amino-benzthiazole # N-diethyl-mamino-acetanilide or N-diethyl-m-amino-stearanilide, (2) 6-ethoxy-2-amino-benzthiazole - m-amino-acetanilide, which gives on cellulose acetate yarn, from an aqueous dispersion, bright bluish red dyeings capable of diazotization on the fibre and development with N-diethylaniline, N-di-(#-hydroxyethyl)-m-toluidine or N-diethyl-m-amino-acetanilide, (3) 6-acetylamino-2-amino-benzthiazole # N-di-(#- hydroxylethyl)-m-amino-acetanilide. An example is also given of the dyeing of a cellulose acetate knitted fabric with the azo dye of (1) above. Specification 440,113 is referred to. 6- Acetylamino-2-aminobenzthiazole and 6- benzoylamino-2-aminobenzthiazole are obtained by adding bromine to solutions of p-aminoacetanilide and p-aminobenzanilide respectively in glacial acetic acid containing ammonium thiocyanate. N-diethyl-m-amino-stearanilide and N-diethyl-m-amino-benzanilide are obtained by the action of stearic acid chloride and benzoyl chloride respectively on 3-diethylaminoaniline.
