Description

  

      Zellulosefolie.       Für gewisse     Verwendungszwecke,    z. B.  als Verpackungsmaterial ist die Durchsichtig  keit der üblichen     Zellulosefolien    manchmal  nachteilig. Man hat deshalb bereits undurch  sichtige Folien hergestellt, indem man     Zellu-          losemassen    verarbeitete, die Pigmente ent  hielten, doch ist dieses     Verfahren    ziemlich  umständlich und kostspielig, da man auf Pig  mente mit ganz besonderen Eigenschaften  hinsichtlich Korngrösse usw. angewiesen ist,  wenn gleichmässige Produkte erhalten wer  den sollen.  



  Es wurde nun gefunden, dass man auf  viel einfacherem Wege undurchsichtige Fo  lien erzeugen kann,     wenn    man farblose oder  gefärbte durchsichtige     Zellulosefolien    wenig  stens auf einer Seite mit einem     pigment-          haltigen    Lacküberzug versieht.  



       Gegenstand    der     Erfindung    ist demnach  eine     Zellulosefolie,    die dadurch gekennzeich  net ist, dass sie mindestens auf einer Seite mit  einem     pigmenthaltigen    Lacküberzug ver  sehen ist.    Der Überzug kann aus einem beliebigen  Lack bestehen, wobei man vorzugsweise sol  che wählt, die sich infolge ihres Lösungsver  mögens mit der     Folienoberfläche    gut ver  binden. Als Farbstoff kann der Lack eines  oder mehrerer der zur Herstellung von An  strichfarben üblichen farblosen oder gefärb  ten Pigmente enthalten.  



       Gewünschtenfalls    kann der     pigment-          haltige    Überzug gegen mechanische und  atmosphärische Einflüsse noch durch eine  Lackschicht oder eine Deckschicht aus Wachs  oder     Paraffin    geschützt werden.  



  Die so erhaltenen Folien weisen, wie sich  zeigte, die gleich guten Eigenschaften bezüg  lich Geschmeidigkeit, und sofern man die  Pigmentschicht nur einseitig     aufbringt,    des  hohen Glanzes auf wie das durchsichtige Ma  terial. Bei     Verwendung    farbiger Folien     und     weisser Pigmente oder farbiger Pigmente und  farbloser oder gefärbter Folien wird durch  die Pigmentauflage gegenüber den     durchsich-          .        tigen    Folien ein bedeutend leuchtenderes Aus  sehen erreicht.



      Cellulose film. For certain purposes, e.g. B. as packaging material, the transparency of the usual cellulose films is sometimes disadvantageous. For this reason, opaque foils have already been produced by processing cellulose masses containing pigments, but this process is rather cumbersome and costly, since one has to rely on pigments with very special properties in terms of grain size etc. if uniform products are obtained who should.



  It has now been found that opaque foils can be produced in a much simpler way if colorless or colored transparent cellulose foils are provided with a pigment-containing lacquer coating on at least one side.



       The subject of the invention is therefore a cellulose film which is characterized in that it is provided with a pigment-containing lacquer coating on at least one side. The coating can consist of any varnish, whereby one preferably chooses sol surfaces that bind well with the film surface as a result of their solvent power. As a dye, the paint can contain one or more of the colorless or colored pigments customary for the production of paints.



       If desired, the pigment-containing coating can be protected against mechanical and atmospheric influences by a layer of lacquer or a top layer of wax or paraffin.



  The films obtained in this way have, as has been shown, the same good properties in terms of suppleness and, if the pigment layer is only applied on one side, the high gloss as the transparent material. When using colored foils and white pigments or colored pigments and colorless or colored foils, the pigment layer is transparent to the. term films achieved a significantly brighter look.
