Description
Wykryto, ze mozna otrzymac cenne barwniki jednoazowe, sprzegajac dwuazo- wany kwas 4-nitro-/-aminobenzeno-2-sul- fonowy z takiemi kwasami 2-alkylo-ami- nonaftaleno-sulfonowemi, których reszta alkylowa zawiera 3-5 atomów wegla. Barw¬ niki te—obok dobrej jednostajnosci krycia —wyrózniaja sie bardzo dobra odpornoscia w foluszu, jak równiez sa odporne na pra¬ nie i na dzialanie swiatla. Przy druku za- pomoca wytrawiania na welnie, barwni¬ ki otrzymane wedlug wynalazku zapew¬ niaja czyste biale efekty wytrawien o wy¬ bitnej odpornosci na dzialanie swiatla.Przyklad, 235 cz. 4-nitro-/-amino- benzeno-2-sulfonianu amonowego dwuazu- je sie jak zwykle i sprzega w roztworze kwasnym (przy próbie wzgledem kongo) z 279 cz. kwasu 2-i-butyloamino-naftale- no-7-sulfonowego. Po skonczonej reakcji wytwarzania sie barwnika, zwiazek ten przeprowadza sie w sól sodowa, wysala, odsacza i suszy.Otrzymany barwnik barwi welne w ka¬ pieli kwasnej na fioletowo w odcieniu niebieskim; zabarwienia te sa odporne na pranie, folusz i dzialanie swiatla.Zastepujac kwas 2-i-butyloamino-naf- taleno-7-sulfonowy kwasem 2-n butyloa- mino-fraftaleno-7-sulfonowym, otrzymuje sie barwnik dajacy mocniejsze czerwone zabarwienie, o takich samych pozostalych wlasnosciach jak wyze]; podobne barwni¬ ki powstaja przy stosowaniu kwasów 2-butylo- lub 2-amyloaminonaftaleno-6-sul- fonowego. # PLIt has been found that valuable monoazo dyes can be obtained by combining 4-nitro - / - aminobenzene-2-sulfonic acid with diazotium with such 2-alkyl-amino-naphthalene-sulfonic acids, the alkyl moiety of which contains 3-5 carbon atoms. These dyes - apart from good uniformity of hiding - are distinguished by very good resistance in the foil, and they are also resistant to washing and light. When printing with wool etching, the dyes obtained according to the invention provide a pure white etch effect with excellent lightfastness. Example, 235 parts Ammonium 4-nitro - / - aminobenzene-2-sulfonate is diazotized as usual and refluxed in an acidic solution (congo test) with 279 parts of 2-i-butylamino-naphthalene-7-sulfonic acid. After the dye formation reaction is complete, this compound is converted into the sodium salt, salted, drained and dried. The dye obtained dyes wool in an acid bath in a violet shade of blue; These colors are resistant to washing, foil and the action of light. By replacing 2-i-butylamino-naphthalene-7-sulfonic acid with 2-n butylamino-naphthalene-7-sulfonic acid, the result is a dye giving a stronger red color, the same other properties as the above]; similar dyes are produced when 2-butyl or 2-amylaminonaphthalene-6-sulfonic acids are used. # PL
