Description

Wykryto, ze mozna otrzymywac cenne, nierozpuszczalne w wodzie barwniki azo¬ we, sprzegajac amidy kwasu acetyloocto- wego, w których atom wodoru grupy ami¬ dowej jest zastapiony reszta benzotiazolu wzglednie podstawionego benzotiazolu, ze skladnikami dwuazowania, niezawierajace- mi grup, które czynia zwiazki te rozpu- szczalnemi w wodzie.Barwniki, otrzymywane w ten sposób, barwia naogól w odcieniach zóltych, a wy¬ tworzone zabarwienia odznaczaja sie bar¬ dzo dobra odpornoscia na dzialanie swiatla i chloru.Przyklad I. 6 g acetooctowokarboylo- 2'-amino-6'-etoksy-benzotiazolu rozpuszcza sie w 5 cm3 lugu sodowego o 38°Be oraz 10 cm3 czerwonego oleju tureckiego i dopelnia woda do litra. 50 g przedzy bawelnianej zaprawia sie tym roztworem, dodajac soli kuchennej, i wywoluje wybarwienie roztworem, zawie¬ rajacym 1,42 g dwuazowanego l-a.mmo-2- metylo-5-chlorobenzenu i zobojetnionym octanem sodowym, nastepnie plócze i na¬ mydla. Otrzymuje sie jasna zólcien o bar¬ dzo dobrej trwalosci.Przyklad II. 50 g przedzy bawelnianej zaprawia sie roztworem, opisanym w przy¬ kladzie I. Przez wywolywanie wybarwienia roztworem, zawierajacym 1,52 g dwuazo¬ wanego ^-amino-2-nitro-4-metylobenzenu i zobojetnionym octanem sodowym, otrzy¬ muje sie, po wyplókaniu i namydleniu prze-dzy, zólcien o czerwonym odcieniu i o bar¬ dzo dobrej trwalosci.Przyklad III. 50 g przedzy bawelnianej zaprawia sie, jak w przykladzie L Przez wywolywanie wybarwienia roztworem, za¬ wierajacym 1,42 g dwuazowanego ./-amino- 2-imetylo-4-chlorobenzenu i zobojetnionym octanem sodowym, otrzymuje sie, po wy- plókaniu i namydleniu przedzy, piekna zól¬ cien.Przyklad IV. Przedze bawelniana za¬ prawia sie wedlug przykladu I, wywoluje wybarwienie roztworem, zawierajacym 1,27 g dwuazowanej o-chloro-aniliny i zobojet¬ nionym octanem sodowym. Po wyplókaniu i namydleniu przedzy otrzymuje sie jasna zólcien o odcieniu zielonym i o dobrej trwa¬ losci. PLIt has been found that it is possible to obtain valuable water-insoluble azo dyes by coupling acetoacetic acid amides in which the hydrogen of the amide group is replaced with a benzothiazole residue of a relatively substituted benzothiazole, with diazotization components not containing the groups that make the compounds These are water-soluble. The dyes obtained in this way dye generally in shades of yellow, and the colors produced have a very good resistance to the action of light and chlorine. Example I. 6 g acetoacetocarboylo-2'-amino- The 6'-ethoxy-benzothiazole is dissolved in 5 cm3 of sodium liquor at 38 ° Be and 10 cm3 of Turkish red oil and made up to one liter with water. 50 g of cotton yarn is seasoned with this solution, with the addition of common salt, and the color is developed with a solution containing 1.42 g of diazotized 1-a.mmo-2-methyl-5-chlorobenzene and neutralized sodium acetate, then fluff and soapy. A light yellow with a very good durability is obtained. Example II. 50 g of cotton yarn is seasoned with the solution described in Example I. By developing a dye with a solution containing 1.52 g of diazotized β-amino-2-nitro-4-methylbenzene and neutralized sodium acetate, it is obtained after softening and soaping of yellows with a red tint and very good durability. Example III. 50 g of cotton yarn are seasoned, as in Example L. By developing a dye with a solution containing 1.42 g of diazotized amino-2-imethyl-4-chlorobenzene and neutralized sodium acetate, it is obtained, after spinning and soaping yarns, beautiful yellow. Example IV. The cotton yarn is repaired according to Example 1, and develops a color with a solution containing 1.27 g of diazotized o-chloroaniline and neutralized sodium acetate. After washing and soaping, the yarn is light yellow with a green tinge and good durability. PL
