<tb>  abfiltriert; <SEP> säurefrei <SEP> gewaschen <SEP> und <SEP> ge  trocknet.
<tb>  



  Der <SEP> neue <SEP> Monozofarbstoff <SEP> färbt <SEP> Acetat  kunstseide <SEP> und <SEP> Polyesterfasern <SEP> leuehtend
<tb>  "eharlaclirot <SEP> mit <SEP> hervorragender <SEP> Licht-,
<tb>  -Wrieh-, <SEP> (las <SEP> Fume- <SEP> und <SEP> Sublimiereehtheit.
