  Verfahren zur Darstellung eines für die Farblackbereitung geeigneten
Kondensationsproduktes. 



   Behandelt man 4-Chlor-6-nitro-1-aminobenzol mit Formaldehyd, so erhält man ein Kondensationsprodukt, dem vermutlich die Formel zukommt. 
 EMI1.1 
 



   Die Kondensation kann in der verschiedensten Weise, z. B. in Gegenwart \on Alkohol, Wasser usw. vorgenommen werden. 



   Es hat sich gezeigt, dass sich dieses neue   Kondensationsprodnkt   in hervorragender Weise zur Herstellung von Farblacken eignet. Diese Lacke zeichnen sich   durch eine schone.   leuchtend rötlich gelbe Nuance und ganz hervorragend gute Lichtechtheit aus. 



   Beispiel 345 Teile einer lOprozentigen Paste von 4-Chlor-6-nitro-I-aminobenzol werden mit 30 Teilen einer 30prozentigen Formaldehydlösung versetzt und in einem geschlossenen Gefäss unter Rühren solange auf   90-95'erwärmt,   bis keine diazotierbare Substanz mehr nachzuweisen ist. Nach dem Erkalten wird abgesaugt, mit Wasser   gewaschen   und entweder bei gelinder Wärme getrocknet oder in Pastenform gebracht. Das so erhaltene   leuchtend rötitchgelbe Produkt   ist unlöslich in Wasser und   wenig löslich in   den   gebrauch-

  Process for the representation of a suitable for the color lacquer preparation
Condensation product.



   If 4-chloro-6-nitro-1-aminobenzene is treated with formaldehyde, a condensation product is obtained which presumably has the formula.
 EMI1.1
 



   The condensation can take place in a variety of ways, e.g. B. be made in the presence of alcohol, water, etc.



   It has been shown that this new condensation product is excellently suited for the production of colored lacquers. These paints are characterized by a beautiful. bright reddish yellow shade and excellent lightfastness.



   Example 345 parts of a 10 percent paste of 4-chloro-6-nitro-1-aminobenzene are mixed with 30 parts of a 30 percent formaldehyde solution and heated to 90-95 ° in a closed vessel with stirring until no more diazotizable substance can be detected. After cooling, it is filtered off with suction, washed with water and either dried under mild heat or made into a paste. The bright reddish yellow product obtained in this way is insoluble in water and not very soluble in use.
