Description

Verfahren zur Herstellung gefärbter Lacke Es hat sich gezeigt, daß die starkfarbigen, aber bisher in der Farbtechnik nicht verwendeten Kondensationsprodukte aromatischer Aldehyde mit Pyrazolonen, ihren Abkömmlingen und Analogen sich hervorragend zum Färben von Lacklösungen, beispielsweise von celluloseesterhaltigen Lacken, eignen. Die Farbstoffe der genannten Klasse zeigen neben vorzüglicher Löslichkeit eine überraschende Lichtbeständigkeit bei großer Farbstärke und Schönheit des Tones.Process for the production of colored lacquers It has been shown that the strongly colored, but so far not used in color technology aromatic aldehydes with pyrazolones, their derivatives and analogues are excellent for coloring lacquer solutions, for example lacquers containing cellulose esters. The dyes of the class mentioned show, in addition to excellent solubility, a surprising one Lightfastness with great color strength and beauty of the tone.

Beispiel 2 Teile der Benzylidenverbindung des Phenvimethylpyrazolons werden in ioo Teile eines Zaponlackes von üblicher Zusammensetzung bei gewöhnlicher Temperatur eingerührt. Nach kurzer Zeit ist die Lösung gebrauchsfertig. Sie gibt einen Aufstrich von intensiv gelber Farbe und hervorragender Lichtechtheit.Example 2 Parts of the benzylidene compound of phenvimethylpyrazolone are in 100 parts of a zapon varnish of the usual composition with the usual Temperature stirred. The solution is ready to use after a short time. She gives a spread of intense yellow color and excellent lightfastness.

Ersetzt man die Benzylidenverbindung durch o,5 Teile des Kondensationsproduktes aus p-Diäthylaminobenzaldehyd mit Phenylmethylpyrazolon, so erhält man ein ebenfalls gut lichtechtes Orange.If the benzylidene compound is replaced by 0.5 parts of the condensation product from p-diethylaminobenzaldehyde with phenylmethylpyrazolone, one also obtains a good lightfast orange.
