Abstract: 514,708. Printing textiles, etc.; ethers of thiocarboxylic acid amides. SOC. OF CHEMICAL INDUSTRY IN BASLE. May 13, 1938, Nos. 14331 and 14332. Convention dates, May 13, 1937 and April 22, 1938. [Classes 2 (iii) and 15 (ii)] [Also in Group XV] Textile fabrics and other materials, e.g., leather, paper, pasteboard or wood, are printed with the use, as an assistant, of a compound of the general formula wherein R1 represents a substituted or unsubstituted alkyl residue, R2 represents a substituted or unsubstituted alkylene residue and R3 and R4 each represent H or an alkyl or hydroxyalkyl residue. The uses of the preparations for book printing and for lithographic printing are referred to. Specified compounds are methyl-, ethyl- and #-hydroxyethyl-thioglycollic acid amides, ethylthioglycollic acid methyl, dimethyl-, ethyl-, diethyl- and #-hydroxyethyl-amides, butylthioglycollic acid amide and the condensation products from ethylene dimercaptan (1 mol.) and chloracetamide or alpha- or #-bromopropionic acid amide (2 mols.) or from methyl chloromethyl ether (1 mol.) and thioglycollic acid amide (1 mol.). They may be used in conjunction with other adjuvants, e.g., urea, benzylsulphanilic acid, resorcinol, sugar, salts of dimethylaminobenzoic acids, cymenesulphonamide, alkali salts of monobutyl phthalate, glycol monobutyl ether and glycerol. In examples; (1) cotton or regenerated cellulose is printed with an aqueous preparation containing helindone violet BB, potash thickening (containing wheat starch, tragacanth, British gum, potassium carbonate, glycerol and water), sodium hydrosulphide and ethylthioglycollic acid amide, dried, steamed, washed and soaped to obtain an intense violet pattern, (2) the dyestuff in (1) is replaced by 6 : 6<1>-diethoxytbioindigo or a brominated indigo, (3) the dyestuff in (1) is replaced by Cibanone violet R, (4) cotton is printed with an aqueous preparation containing the sulphuric acid ester of leuco-5 : 5<1>-dichloro-7: 7<1>-dimethylthioindigo, starch-tragacanth thickening, ammonium sulphocyanide, sodium chlorate, vanadium chloride, ammonia and ethylthioglycollic acid amide, dried, steamed, washed and soaped to obtain an intense pure violet pattern, (5) cotton or regenerated cellulose is printed with an aqueous preparation containing the diazoami to compound of 4-chloro-1-amino-2- methylbenzene and 4-sulpho-2-aminobenzoic acid, 2-acetoacetylamino-6-ethoxybenzthiazole, starch'tragacanth thickening, caustic soda and ethylthioglycollic acid amide or monomethylamide, dried, steamed in acid vapour, rinsed and soaped to obtain an intense yellow pattern, (6) cotton. is printed with an aqueous preparation containing the product of the action of m-benzoic acid sulphochloride on the azo' dyestuff, m-chloraniline # the anilide of 2 : 3- hydroxynaphthoic acid, starch tragacanth thickening, trisodium phosphate, urea and ethylthioglycollic acid amide, dried, steamed, passed through dilute sodium hydroxide, rinsed, soured, rinsed and soaped to obtain a fast brilliant orange pattern, (7) cotton is printed with an aqueous preparation containing the product of the action of benzoyl chloride-msulphonic acid on the azo dyestuff, 2:5- dichloraniline# the o-anisidide of 2 : 3-hydroxynaphthoic acid, starch tragacanth thickening, trisodium phosphate and methylthioglycollic acid amide, dried and further treated as in (6) to obtain a fast clear scarlet red pattern (8) cotton is printed with an aqueous preparation containing the product of the action of benzoyl chloride-m-sulphonic acid on the azo dyestuff, 4: 4<1>-dichloro-2-aminodiphenyl ether # the o-anisidide of 2 : 3-hydroxynaphthoic acid, starch tragacanth thickening, trisodium phosphate and #-hydroxyethylthioglycollic acid amide, dried and further treated as in (6) to obtain a fast clear red pattern, (9) cotton is printed with an aqueous preparation containing Indulin R base, acid starch thickening, acetic acid, tannin and ethylthioglycollic acid amide, dried, steamed, passed through tartar emetic solution, washed and soaped to obtain an intense dark blue pattern. Specifications 480,358 and 482,814 are referred to. Ethers of mercaptocarboxylic acid amides, above referred to, are obtainable (a) by reaction of an alkylthioglycollic acid ester with ammonia or an alkylamine, (b) by condensation of a halogenated alkyl carboxylic acid amide or mono- or di-alkyl-substituted amide with an - aliphatic mercaptan.
