Description

Verfahren zum Färben von hochmolekularen organischen plastischen Massen Es wurde gefunden, ,daß man hochmolekulare organische plastische Massen, insbesondere Kautschuk und kautschukähnliche Massen, in sehr vorteilhafter Weise färben kann, wenn man: den genannten Massen durch Kuppeln von i bzw. 2 Mal diazotiertern o-An.isidin mit i Mol Diacetacetvl-o-tolidinid oder dessen Derivaten erhältliche, .in Wasser unlösliche Azofarbstoffe einverleibt.Process for coloring high molecular organic plastic masses It has been found that high molecular weight organic plastic masses, in particular Can color rubber and rubber-like masses in a very advantageous manner, if you: the mentioned masses by coupling i or 2 times diazotized o-anisidine obtainable with 1 mole of diacetacetyl-o-tolidinide or its derivatives, in water incorporated insoluble azo dyes.

Beispiel I .In eine für die Pressevulkanisation geeignete Kautschukmischung, enthaltend Füllstoffe, Schwefel und Vulkanisationsbesch.leuniger, werden 2 % des aus i Mol diazotiertem o-Anisidin und i. Mol Di-acetacetyl-o-tolidinid erhaltenen Farbstoffes eingemischt. Die Mischung wird darauf in .der Presse bei einer i 5o' nicht übersteigenden Temperatur vulkanisiert. Man erhält ein grünstichig gelbes Vulkanisat. Der Farbstoff ist vuIkanisierecht, d. h. er wird .durch das Vulkanisieren nicht zerstört.Example I. In a rubber mixture suitable for press vulcanization and containing fillers, sulfur and vulcanization accelerators, 2 % of the o-anisidine diazotized from 1 mole and i. Mol di-acetacetyl-o-tolidinide obtained dye mixed. The mixture is then vulcanized in the press at a temperature not exceeding 15 °. A greenish yellow vulcanizate is obtained. The dye is resistant to vulcanization, ie it is not destroyed by vulcanization.

Beispiel 2 Man setzt zu einer für die Pressevulkanisation geeigneten Kautschukmischung 1 °% des aus 2 Mol diazotiertem o-Anisidin und i Mol Diäcetacetyl;o-tolidinid erhältlichen Farbstoffes und erhält nach der Vulkanisation ein rötlichgelbes Vulkanisat. Der Farbstoff blutet in mitverarbeitete Weißmischung nicht aus.Example 2 One sets to one suitable for press vulcanization Rubber mixture 1% of that of 2 moles of diazotized o-anisidine and 1 mole of diacetoacetyl; o-tolidinide available dye and receives a reddish yellow vulcanizate after vulcanization. The dye does not bleed out in the processed white mixture.

Beispiel 3 Ein nicht gehärtetes Ph:enol-Formaldehyd-Kondensationsprodukt wird mit dem im Beispiel 2 verwendeten Farbstoff innig gemischt. Darauf wird das Kondensationsprodukt in der üblichen Weise durch Erhitzen gehärtet.Example 3 An uncured ph: enol-formaldehyde condensation product is intimately mixed with the dye used in Example 2. Then that will Condensation product hardened in the usual way by heating.

Der Farbstoff ist auch zum Färben von Celluloid geeignet.The dye is also suitable for dyeing celluloid.
