Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 173751.    Verfahren zur Herstellung eines transparenten, leuchtend roten Lackes.    Es wurde gefunden, dass es gelingt, einen  transparenten, leuchtend roten Lack mit aus  gezeichneten Echtheitseigenschaften herzu  stellen, indem man den     Xanthen-Farbstoff     aus ,je einem     Mol        Phthalsäure,        Dimethyl-m-          aminophenol    und     ss-Resorcylsäure,    ein Salz  des     2wertigen    Kupfers und einen Lack  zusammenbringt und durch gelindes Erwär  men des Gemisches das rot gefärbte Kupfer  komplexsalz des Farbstoffes sich bilden lässt.

    Man erhält je nach er     Farbstoffkonzentra-          tion    einen heller oder dunkler rot gefärbten,  transparenten Lack von sehr grosser Reinheit  des Farbtones, der hervorragend lichtechte  Anstriche ergibt. Seine Verwendung liegt  auf allen Gebieten der     Anstrichtechnik,    wo  grosse Ansprüche an die Lichtechtheit ge  stellt werden.  



  Als Ausgangslacke kommen die meisten  Lacke und Firnisse der Technik in Frage,  wie     Acetylzellulose-    und     Nitrozelluloselacke,          Lacke    aus Kunstharzen, wie     Glyzerin-Phthal-          säurea.nhydrid-Kondensationsprodukte,    Chlor-         kautschuklacke,        Gelatinelösungen,    Sprit  lacke, Leinöl und     Lithographenfirnisse.     



  <I>Beispiel:</I>  0,5 g des     Xanthen-Farbstoffes    aus je  einem     Mol.        Phthalsäure,        Dimethyl-m-amino-          phenol    und     ss-Resorcylsäure    werden in 100 g       Nitrozelluloselack    gelöst, mit 0,5 g Kupfer  acetat versetzt und durch gelindes. Erwär  men in den hervorragend lichtechten rot  gefärbten Lack übergeführt.  



  Der Nitrolack kann zum Beispiel wie  folgt zusammengesetzt sein:  
EMI0001.0026     
  
    <B>155</B> <SEP> Teile <SEP> Kollodiumwolle <SEP> butanolfeucht
<tb>  400 <SEP> Teile <SEP> Butylacetat
<tb>  20 <SEP> Teile <SEP> Dibutylphthalat
<tb>  25 <SEP> Teile <SEP> Trikresylphosphat

  <B> Additional patent </B> to main patent no. 173751. Process for the production of a transparent, bright red lacquer. It has been found that it is possible to produce a transparent, bright red lacquer with excellent fastness properties by converting the xanthene dye from one mole each of phthalic acid, dimethyl-m-aminophenol and ß-resorcylic acid, a salt of divalent copper and brings together a varnish and the red colored copper complex salt of the dye can be formed by gently heating the mixture.

    Depending on the dye concentration, a lighter or darker red colored, transparent varnish is obtained with a very high degree of purity of the hue, which gives excellent lightfast coatings. Its use is in all areas of painting technology where high demands are placed 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 glycerol-phthalic acid anhydride condensation products, chlorinated rubber lacquers, gelatin solutions, petrol lacquers, linseed oil and lithographic varnishes.



  <I> Example: </I> 0.5 g of the xanthene dye from one mole each of phthalic acid, dimethyl-m-aminophenol and ß-resorcylic acid are dissolved in 100 g of nitrocellulose varnish, and 0.5 g of copper acetate is added and by mild. Warming men transferred to the excellent lightfast red colored lacquer.



  The nitro lacquer can be composed, for example, as follows:
EMI0001.0026
  
    <B> 155 </B> <SEP> parts of <SEP> collodion wool <SEP> butanol damp
<tb> 400 <SEP> parts <SEP> butyl acetate
<tb> 20 <SEP> parts of <SEP> dibutyl phthalate
<tb> 25 <SEP> parts of <SEP> tricresyl phosphate
<tb> 400 <SEP> parts <SEP> ethyl alcohol <SEP> <B> 96%. </B>
