Description

Stosowanie barwików nitrozoamino- wych równoczesnie z innemi barwikami, np. taninowemi lub chromowemi, albo z czernia anilinowa, w wielobarwnym druku bylo dotychczas niemozliwe, po¬ niewaz barwiki nitrozoaminowe, t. zw. mieszaniny nitrozoaminów i naftoli, nie znosza nawet krótkiego zaparzania, tra¬ cac przytem, albo wydatnie na sile i blednac, lub zmieniajac ton, przyczem np., barwa czerwona przechodzi w ca- chou i brunatna.Zrobiono spostrzezenie, ze dodanie neutralnych chromianów, lub innych soli metalicznych, np. weglanu alkaljo-glino- wego, boranu glinowego, albo soli so¬ dowej kwasu wanadynowego, a wiec zwiazków, które z azobarwikami tworza odporne na zaparzanie laki, do barwi¬ ków nitrozoaminowych sprawia, ze oma¬ wiane nitrozoaminowe barwiki sa w do¬ statecznej mierze odporne na zaparzanie, tak ze przy uzyciu takich nitrozoamino¬ wych farb drukarskich udaje sie, takze po zaparzaniu, wywolac barwik w pelnej sile i w czystym tonie.Takie nitrozoaminy, zawierajace neu¬ tralne chromiany, lub wspomniane sole, moga byc zaparzane w Matherplacie, lub innych urzadzeniach, z równoczesnie wydrukowanemi innemi barwikami; nie okazuja sie przytem wspomniane wyzej ujemne strony, jak to mialo miejsce w dotychczasowych sposobach.Jako naftole wchodza tu pod uwage wszystkie oxynaftaliny, zdolne do two¬ rzenia azobarwików, wiec prócz samych naftoli takie ich pochodne, jak arylidyi hydrazydy oxynaftoesowego kwasu, aminonaftole, acidyloaminonaftole, albo ciala podobne.Znane sa sposoby rezerwowania in- dygo zapomoca nitrozoaminobeta-nafto- lowych barwików, przy równoczesnem uzyciu chromianów, obok innych takze i obojetnego chromianu alkaljów.Jednak nie mozna bylo przewidziec, ze przy dodaniu monochromianów do nitrozoaminowych barwików, mozna do¬ brze wywolac barwik takze po zaparzaniu.Przedlozony sposób przedstawia waz¬ ny postep techniczny, poniewaz dzieki niemu mozna wykonac w drukarstwie wiele nowych kombinacyj i, co dotych¬ czas bylo niemozliwem, równoczesnie z barwnikami nitrozoaminowemi, druko¬ wac barwiki taninowe, chromowe, siar¬ kowe i kadziowe.Sposób ten mozna tak przeprowadzac, ze drukuje sie na bialym towarze bar¬ wiki, wymienione w nizej podanych przykladach, potem suszy, zawiesza, za¬ parza 5 do 10 minut w Matherplacie i wywoluje w gotujacej kapieli octowo- glauberskiej, lub octowo-dwuchromiano- wej, przyczem przy barwikach tanino- wych dodaje sie jeszcze sól antymonowa.A.

PLThe use of nitrosamine dyes simultaneously with other dyes, for example tannin or chrome or aniline black, has hitherto been impossible in multi-colored printing, because nitrosamine dyes, i.e. mixtures of nitrosamines and naphtholes, can not tolerate even a short brewing, thereby losing either significantly in strength and fading or changing the tone, for example, the red color changes into whole and brown. Observed that the addition of neutral chromates, or other metal salts, for example, aluminum-alkali carbonate, aluminum borate, or sodium vanadic acid, i.e. compounds which form steep-resistant lacquers with azo-aromas, for nitrosamine dyes, makes the talked nitrosamine dyes are reasonably resistant to scalding, so that with such nitrosamine inks it is possible, even after infusion, to develop the dye in full strength and in a pure tone. Such nitrosamines containing neural chromate or the mentioned salts can be brewed in Matherplat or other devices, with other colors printed at the same time; The disadvantages mentioned above do not appear, as was the case with the methods used so far. As naphtholes, all oxynaphthalines capable of forming azobarvides are considered here, so apart from naphthols themselves, such derivatives as oxynaphthalic acid arylides and hydrazides, aminonaphthols, acidylaminonaphthols There are methods of reserving indigo with nitrosaminobeta-naphthol dyes, while using chromates, along with others, also inert alkali chromate. However, it could not be predicted that when adding monochromates to nitrosamine dyes, it was possible to add It is very important to develop a dye even after brewing. The presented method represents an important technical advance, because thanks to it it is possible to make many new combinations in printing and, which was not possible until now, simultaneously with nitrosamine dyes, to print tannin, chromium, sulfur dyes. and vat; this method can be done so that it is printed on white The barwiki goods mentioned in the examples below are then dried, suspended, brewed for 5 to 10 minutes in Matherplata and developed in a boiling vinegar-glauber or acetic-dichromate bath, and additionally added with tannins. antimony salt A.
