Description

       

      Terfahren    zur     Herstellung    eines transparenten, blauen Lackes.    Es wurde gefunden, dass es gelingt, einen  transparenten, blauen Lack mit ausgezeich  neten Echtheitseigenschaften herzustellen, in  dem man     Eriochromazurol    B     (Schultz,        Farb-          stofftabellen,    7. Auflage, Nr. 838), eine Ver  bindung des     6-wertigen    Chroms und einen  Lack zusammenbringt und durch gelindes  Erwärmen des Gemisches das blau gefärbte       Chromkomplexsalz    des Farbstoffes sich bilden  lässt.

   Man erhält je nach der     Farbstoffkon-          zentration    einen heller oder dunkler blau  gefärbten, transparenten Lack von sehr grosser  Reinheit des Farbtons, der hervorragend licht  echte Anstriche ergibt. Seine Verwendung  liegt auf allen Gebieten der     Anstrichtechnik,     wo grosse Ansprüche an die Lichtechtheit  gestellt werden.  



  Als Ausgangslacke kommen die meisten  Lacke und Firnisse der Technik in Frage,  wie     Acetylcellulose-    und     Nitrocelluloselacke,     Lacke aus Kunstharzen, wie     Glyeerin-Phthal-          bäureanliydrid-Kondensationsprodukte,    Chlor  kautschuklacke,     Gelatinelösungen,        Spritlacke,     Leinöl- und     Lithographerifirnisse.       <I>Beispiel:

  </I>  1     gr        Eriochromazurol    B (Schultz,     Farb-          stofftabellen    1931,     No.    838) wird in 100     gr          Nitrocelluloselack    gelöst und mittelst 0,5     gr          Natriumbichromat    unter gelindem Erwärmen  in den leuchtend klaren, blauen Lack über  geführt; seine Lichtechtheit ist hervorragend.  



  Der     Nitrocelluloselack    kann z. B. folgende  Zusammensetzung haben  155 Teile     Kollodiumwolle        butanolfeucht     400 Teile     Butylacetat     20 Teile     Dibutylphthalat     25 Teile     Trikresylphosphat     400 Teile Äthylalkohol 96  /o.  



  Statt des     Farbstoffsalzes    kann ebenso gut  mit gleicher Wirkung die freie     Farbstoffsäure     verwendet werden.



      Terfahren for the production of a transparent, blue paint. It has been found that it is possible to produce a transparent, blue lacquer with excellent fastness properties by using Eriochromazurol B (Schultz, color tables, 7th edition, no. 838), a compound of hexavalent chromium and a The paint brings together and the blue colored chromium complex salt of the dye can be formed by gently heating the mixture.

   Depending on the dye concentration, a lighter or darker blue colored, transparent varnish is obtained with a very high degree of purity of the hue, which gives excellent lightfast coatings. It is used in all areas of painting technology where high demands are made on lightfastness.



  Most technical lacquers and varnishes can be used as starting lacquers, such as acetyl cellulose and nitrocellulose lacquers, lacquers made from synthetic resins, such as glycerin-phthalic anhydride condensation products, chlorine rubber lacquers, gelatin solutions, fuel lacquers, linseed oil and lithography varnishes. <I> example:

  </I> 1 gram of Eriochromazurol B (Schultz, color tables 1931, No. 838) is dissolved in 100 gram of nitrocellulose lacquer and converted into the bright, clear, blue lacquer with 0.5 gram of sodium dichromate while gently warming up; its lightfastness is excellent.



  The nitrocellulose varnish can e.g. B. The following composition has 155 parts of collodion wool butanol moist 400 parts of butyl acetate 20 parts of dibutyl phthalate 25 parts of tricresyl phosphate 400 parts of ethyl alcohol 96 / o.



  Instead of the dye salt, the free dye acid can just as easily be used with the same effect.
