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.
