Description

Wykryto, ze otrzymuje sie latwo roz¬ puszczalne w wodzie zasadowe barwniki trójfenyloinetanowe O' bardzo dobrej od¬ pornosci na dzialanie swiatla i dajace czy¬ ste zabarwienia, kondensujac w ilosciach czasteczkowych czterohydro - oksyalkylo - dwuaminobenzofenony, podstawione lub riiepodstawione, z p - alkoksy- lub p - al- kylo - dwufenyloaniina.Przyklad L Kondensujac w sposób zwykly jedna czasteczke 4,4* - czterohy- droksyetylodwuaminobenzofenonu z jedna czasteczika 4 - etoksydwufenyloaniiny w o- becnosci tlenochlorku fosforu, otrzymuje sie barwnik, bardzOi dobrze rozpuszczajacy sie w wodzie, który barwi bawelne, trak¬ towana tanina, welne i jedwab na jaskra¬ we odcienie niebieskie o wybitnej trwalo¬ sci na dzialanie swiatla i który posiada wzór nastepujacy:HOH4C^ HOH.C/ N: CMiOH / x N-C2H4OH CI C I I NH I I OCH, Przyklad II. Przez kondensacje jed¬ nej czasteczki 4,4' - czterohydroksyetylo- dwuamino - 2,2' - dwumetylo - benzofeno- nu z jedna czasteczka 4 - metylodwufeny- loaminy w obecnosci tlenochlorku fosforo¬ wego otrzymuje sie barwnik niebieski, bar¬ dzo dobrze rozpuszczajacy sie w wodzie, który posiada bardziej zielona barwe, niz barwnik, przytoczony w przykladzie I, i który, posiadajac taka sama odpornosc, odpowiada wzorowi nastepujacemu: HOHAC^ HOHtCo N- \ CH, C C2ff40r7 / N-CiHfili Cl CH2 NH CH.A — 2 — PLIt has been found that water-soluble basic triphenylethane dyes of very good light fastness and a pure color are obtained by condensing in molecular amounts tetrahydro - oxyalkyl - diaminobenzophenones, substituted or disubstituted, or with p - alkoxy p-Alkyl-diphenylanin. Example L Condensing in the usual manner one molecule of 4,4 * - tetrahydroxyethyl diaminobenzophenone with one molecule of 4-ethoxydiphenylanin in the presence of phosphorus oxychloride, a dye is obtained which is very and well soluble in water. cotton, treated tannin, wool and silk, bright blue shades with outstanding lightfastness and which has the following formula: HOH4C ^ HOH. C / N: CMiOH / x N-C2H4OHCII NH II OCH, Example II. By condensation of one molecule of 4,4'-tetrahydroxyethyl-diamino-2,2'-dimethyl-benzophenone with one molecule of 4-methyldiphenylamine in the presence of phosphorus oxychloride a blue dye is obtained, which dissolves very well in water, which has a greener color than the dye in example I, and which, while having the same resistance, corresponds to the formula: HOHAC ^ HOHtCo N- \ CH, C C2ff40r7 / N-CiHfil Cl CH2 NH CH.A - 2 - PL
