      Verfahren    zur     Darstellung    eines     Acetatseidenfarbstoifes.     
EMI0001.0004     
  
    Gegenstand <SEP> dieses <SEP> Zusatzpatentes <SEP> ist <SEP> ein
<tb>  Verfahren <SEP> zur <SEP> Darstellung <SEP> eines <SEP> Acetatseiden  farbstoffes <SEP> dadurch <SEP> gekennzeichnet, <SEP> dass <SEP> man
<tb>  -1-Aininoriaphtalsäui@eanhydi-id <SEP> mit <SEP> Cyklohex  yIainin <SEP> kondensiert.
<tb>  



  <I>Beispiel.:</I>
<tb>  50 <SEP> Gewichtsteile <SEP> -: <SEP> - <SEP> Ariiirionaphtalsäui,e  anliydrid <SEP> werden <SEP> mit <SEP> 1.,50 <SEP> Raumteilen <SEP> Cyklo  hexylaulin <SEP> zum <SEP> Sieden <SEP> erhitzt. <SEP> Nach <SEP> dem
<tb>  Abkühlen <SEP> wird <SEP> abgesaugt, <SEP> mit <SEP> Sprit <SEP> gewa  tthen <SEP> und <SEP> getrocknet. <SEP> Der <SEP> Farbstoff <SEP> stellt
<tb>  ein <SEP> gelbes <SEP> Pulver <SEP> dar, <SEP> welches <SEP> bei <SEP> \?40  <SEP> bis
<tb>  2420 <SEP> C <SEP> schmilzt <SEP> und <SEP> Celluloseester <SEP> oder <SEP> -äther
<tb>  -Aer <SEP> deren <SEP> LTmwandlungsprodukte <SEP> in <SEP> sehr            grünstichiggelben    Tönen färbt, von     starker     grüner Fluoreszenz.



      Process for the preparation of an acetate silk dye.
EMI0001.0004
  
    The subject of this <SEP> additional patent <SEP> is <SEP> a
<tb> Method <SEP> for <SEP> representation <SEP> of a <SEP> acetate silk dye <SEP> characterized by <SEP>, <SEP> that <SEP> man
<tb> -1-Aininoriaphtalsäui @ eanhydi-id <SEP> with <SEP> Cyklohex yIainin <SEP> condensed.
<tb>



  <I> Example .: </I>
<tb> 50 <SEP> parts by weight <SEP> -: <SEP> - <SEP> Ariiirionaphtalsäui, e anliydrid <SEP> become <SEP> with <SEP> 1., 50 <SEP> parts by volume <SEP> Cyclo hexylaulin <SEP > heated to <SEP> boiling <SEP>. <SEP> After <SEP> the
<tb> Cooling down <SEP> <SEP> is sucked off, <SEP> with <SEP> fuel <SEP> checked <SEP> and <SEP> dried. <SEP> The <SEP> dye <SEP> represents
<tb> represents a <SEP> yellow <SEP> powder <SEP>, <SEP> which <SEP> at <SEP> \? 40 <SEP> to
<tb> 2420 <SEP> C <SEP> melts <SEP> and <SEP> cellulose ester <SEP> or <SEP> -ether
<tb> -Aer <SEP> whose <SEP> conversion products <SEP> colors in <SEP> very greenish yellow tones, with strong green fluorescence.
