Es <SEP> wurde <SEP> gefunden, <SEP> dass <SEP> ein <SEP> wertvoller,

<tb> Konstitution <SEP> entsteht, <SEP> wenn <SEP> man <SEP> den <SEP> aus
<tb> einem <SEP> Gemisch <SEP> von <SEP> diazotierter <SEP> 2,5- <SEP> und <SEP> 2,8 Naphtylaininsulfosäure <SEP> und <SEP> Resorcin <SEP> erhält lichen <SEP> 1Ionoazofarbstoff <SEP> bei <SEP> Gegenwart <SEP> von
<tb> wässeri",rn <SEP> Ammoniak <SEP> mit <SEP> Oxydationsmit teln, <SEP> vorzugsweise <SEP> mit. <SEP> Luft, <SEP> behandelt.
<SEP> Der
<tb> neue <SEP> Farbstoff <SEP> stellt <SEP> ein <SEP> dunkles <SEP> Pulver <SEP> dar,
<tb> Idas <SEP> sich <SEP> in <SEP> Wasser <SEP> mit <SEP> gelbbrauner. <SEP> in <SEP> kon entrierter <SEP> Schwefelsäure <SEP> mit <SEP> rotbrauner
<tb> ;Farbe <SEP> löst. <SEP> Im <SEP> Gegensatz <SEP> zum <SEP> Ausgangs farbstoff <SEP> färbt. <SEP> er <SEP> Wolle <SEP> und <SEP> Seide <SEP> kaum
<tb> mehr <SEP> < in, <SEP> dagegen <SEP> erzeugt <SEP> er <SEP> auf <SEP> Leder <SEP> ein
<tb> schönes, <SEP> sattes <SEP> Braun, <SEP> dessen <SEP> Farbton <SEP> von
<tb> dem <SEP> Grade <SEP> der <SEP> Oxydation <SEP> abhängig, <SEP> ist.
<tb> Diese <SEP> Lederfärbungen <SEP> sind <SEP> ausgezeichnet

<tb> <I>Beispiel:
</I>
<tb> Eine <SEP> Lösung <SEP> von <SEP> 24 <SEP> Teilen <SEP> des <SEP> aus <SEP> einem

Die anfänglich gelborange Lösung wird bald tiefbraun. Die Oxydation ist beendet, wenn Nuance und Stärke der Lösung sich nicht mehr ändern, was nach einigen Stunden der Fall ist.
Als dann wird mit Salzsäure angesäuert. mit Kochsalz gefällt. filtriert und getrocknet. Der Farbstoff kann auch direkt durch Ein dampfen der ammoniakalischen Lösung ge wonnen werden. ,
Process for the preparation of a coloring reaction product obtained from an ionoazo dye.
EMI0001.0005
<SEP> was found <SEP>, <SEP> that <SEP> is a <SEP> valuable,
<tb> brown <SEP> dye <SEP> from <SEP> still <SEP> unknown
<tb> Constitution <SEP> arises, <SEP> when <SEP> man <SEP> the <SEP>
<tb> a <SEP> mixture <SEP> of <SEP> diazotized <SEP> 2.5- <SEP> and <SEP> 2.8 naphtylainin sulfonic acid <SEP> and <SEP> resorcinol <SEP> obtainable <SEP> 1ionoazo dye <SEP> in <SEP> presence <SEP> of
<tb> watery ", rn <SEP> ammonia <SEP> treated with <SEP> oxidizing agents, <SEP> preferably <SEP> with. <SEP> air, <SEP>.
<SEP> The
<tb> new <SEP> dye <SEP> represents <SEP> a <SEP> dark <SEP> powder <SEP>,
<tb> Idas <SEP> <SEP> in <SEP> water <SEP> with <SEP> yellow-brown. <SEP> in <SEP> concentrated <SEP> sulfuric acid <SEP> with <SEP> red-brown
<tb>; Color <SEP> solves. <SEP> In the <SEP> contrast <SEP> to the <SEP> output dye <SEP> colors. <SEP> he <SEP> wool <SEP> and <SEP> silk <SEP> hardly any
<tb> more <SEP> <in, <SEP> on the other hand <SEP> generates <SEP> er <SEP> on <SEP> leather <SEP>
<tb> beautiful, <SEP> rich <SEP> brown, <SEP> its <SEP> color <SEP> from
<tb> the <SEP> grade <SEP> of the <SEP> oxidation <SEP> depends, <SEP> is.
<tb> These <SEP> leather colors <SEP> are <SEP> certified
<tb> dureb <SEP> excellent <SEP> authenticity <SEP> against <SEP> light
<tb> and <SEP> alkaline <SEP> fatty liquor.
<tb> <I> Example:
</I>
<tb> A <SEP> solution <SEP> from <SEP> 24 <SEP> parts <SEP> of <SEP> from <SEP> one
<tb> Mixture <SEP> of <SEP> diazotized <SEP> 2,5- <SEP> and <SEP> 2,8- <SEP> naphthylamine sulfonic acid and resorcinol available monoazo dye in 100-150 parts water- # :; 30-50 parts of 20% ammonia are added and air is passed through at about 80 ° C. with stirring. The initially yellow-orange solution soon turns deep brown. The oxidation is over when the shade and strength of the solution no longer change, which is the case after a few hours.
Then it is acidified with hydrochloric acid. like with table salt. filtered and dried. The dye can also be obtained directly by evaporating the ammoniacal solution. ,
