Description

Herstellung von Farbstofftinten. Zusatz zum Patent 430 582, Nach dem Patent ,430 582 werden wasserechte Schrift liefernde Farbstoiftinten dadurch erhalten, daß man den Lösungen substantiver Farbstoffe freies Alkali zusetzt. Die mit diesen Tinten erzeugte Schrift wird erst allmählich wasserecht, und die Wasserechtheit-hängt von dem verwendeten Farbstoff und von der Art der Papierleimung ab.Manufacture of dye inks. Addition to Patent 430 582, According to Patent 430 582, colored pencil inks that provide water-resistant writing are obtained by adding free alkali to the solutions of substantive coloring agents. The writing produced with these inks only gradually becomes waterfast, and the waterfastness depends on the dye used and on the type of paper sizing.

`ach dein Zusatzpatent 431 369 wird den Lösungen substantiver Farbstoffe Formaldehyd allein oder gleichzeitig mit Alkali zugesetzt. Bei Verwendung des Farbstoffs als Ainmoniumsalz im Gemisch mit Formaldelivd ohne Alkalizugabe tritt eine schnellere, unter Umständen sofortige Wasserechtheit ein.Oh your additional patent 431 369 is the solutions of substantive dyes Formaldehyde added alone or at the same time as alkali. When using the dye As the ammonium salt mixed with formaldelivd without the addition of alkali, a faster, under certain circumstances immediate water fastness.

Wie weiter gefunden wurde, erhält man eine Tinte, deren Schrift unmittelbar nach dem Trocknen wasserecht ist, wenn man die Ammoniumsalze oder Alkaliammoniumsalze geeigneter substantiver Farbstoffe allein ohne Zugabe von Alkali oder Formaldehyd in reinem Wasser löst.As was further found, one obtains an ink whose writing is immediate After drying, it is water-fast if you use the ammonium salts or alkali ammonium salts suitable substantive dyes alone without the addition of alkali or formaldehyde dissolves in pure water.

Beispiel i.Example i.

Das säure Natritimsalz eines Farbstoffes der allgemeinen Formel wird finit der zehnfachen Menge destillierten Wassers tuicl so viel Ammoniak gelöst, wie zur Bildung es neutralen Natriumammoniumsalzes nötig ist. Man verdünnt die Lösung finit destilliertem Wasser auf das Siebenfache und erhält so eine Tinte, deren Schrift sofort nach dein Trocknen wasserecht ist. Beispiel e.The acidic sodium salt of a dye of the general formula finitely ten times the amount of distilled water, as much ammonia is dissolved as is necessary to form the neutral sodium ammonium salt. The solution is diluted sevenfold in finite distilled water and an ink is obtained, the writing of which is waterfast immediately after drying. Example e.

i Teil einer Farbsäure der im Beispiel i gegebenen-allgemeinen Formel verrührt man mit 5 Teilen i,37prozentigen Ainnioniaks und stellt nach einigen Stunden mit destilliertem Wasser auf ioo Teile. Die Schrift mit dieser Tinte ist sofort nach dem Trocknen wasserecht.i Part of a dye acid of the general formula given in Example i The mixture is stirred with 5 parts of i, 37 percent Alinnioniaks and sets after a few hours with distilled water to 100 parts. The writing with this ink is instant waterfast after drying.
