Die vorliegende Erfindung betrifft einen Lack, insbesondere zur Herste llung von Zigarettenmundstlickbelagpapieren und ein Verfahren zu dessen Herstellung.The present invention relates to a paint, in particular for the production of cigarette mouthpiece covering papers and a Process for its manufacture.
Zijarefcterünundstückbeläge und Filterumhüllungan werden aus lackierte« und/oder bedruckten Papier gefertigt. Dor hierbei in Anwendung- kommende Lack darf nur aus' bestimmten. Grundstoffen aufgebaut sein* Welcne irfit Schleimhäuten und Halbschleimhäuten aufgrund von Lebensmittel- nnd .Tabak verordnungers in Berührung komraen dürfen,; eine besondere Schwierigkeit bereitete bisher die Einfärouag derartiger Lacke, da organische Farbstoffe dem Lack ohne Zusatz von Pigmenten1 uttd/oder Füll«* stoffe keine oder nicht die gewünschte Einfarbung geben und die meisten Pigmente und Füllstoffe nicht zulässig sind. Die meisten anorganischen Füllstoffe und Pigmente sind unzulässig, denn viele enthalten gesundheitsschädliche Verunreinigun gen. Als anorganische 'Pigments- sind von der Tabaky©ro,rchnmg iiiscivoxjfde züge lassen. Die technischen ßisenoxyde enthalten aber im normalen Zustand scnädliche Verunreinigungen imct find daher nur in einem sehr hohen Reinheitsgrad zulässig·- Reinheitsforclerung ist so hoch, daS durch die Verwendung jiereinigteia- Eisenoxyd die Preisgestaltung seh? schwierig; denn Eisenoxyd rauß in recht großen Mengen Ip.

The lacquer used in this case may only be made from certain.

Most inorganic fillers and pigments are inadmissible, as many contain contaminants that are harmful to health. Tobacco can be used as inorganic pigments. The technical iron oxides contain harmful impurities in their normal state and are therefore only permitted in a very high degree of purity. difficult; for iron oxide in large quantities Ip. "The varnish can be brought in: - when a brown color is achieved" 1098877δ | 3 ^ BAD ORiGi
Hie Hersteller von Zigarsttenmundstückbelagspap'ieren sind nicht in der Lags, dia einschlägigen Vorschriften des Reinheitsgrades (DAB 6) einzuhalten.They are not manufacturers of cigarette mouthpiece covering papers in der Lags, dia relevant regulations of the degree of purity (DAB 6) must be observed.
Die vorliegende Erfindung vermeidet die genannten Wachteile und schafft eine Möglichkeit für die Einfärbung von Lacken, die mit Schleimhäuten und Halbscnleiiühäuteh in Berührung komiaen, mit einem organischen Farbstoff, der für die Berührung mit. Schleim«* häuten und Halbschleimhäuten zulässig ist.The present invention avoids the aforementioned drawbacks and creates a possibility for coloring paints that use Mucous membranes and semicircular membranes come into contact with an organic dye that is suitable for contact with. Mucus"* skin and half-mucous membranes is permitted.
Die Erfindung oenutzt hierfür neben des» organischen Farbstoff einen besonderen Farbstoffträger, der aus Feinstpulver aus Schalen tropischer Früchte, insbesondere aus Mehl von Kokosfschalen, aber auch von Paranüssen! Cuhune, ßabassu oder anderen .tropischen Nüssen hergestellt ist. The invention uses the organic dye for this purpose a special dye carrier made from the finest powder Peels of tropical fruits, especially from coconut shell flour, but also from Brazil nuts! Cuhune, ßabassu or other tropical nuts.
Die Erfindung besteht in der gleichzeitigen Verwendung von für Schleimhäute und Halbschleimhäute zugelassenen organischen Farbstoffen zusammen mit dem Mehl bzw. Feinstpulver aus Scha-, len tropischer Früchte. Der Lack wird dadurch hergestellt, daß als Träger für organische Farbstoffe Mehl bzw. Feinstpul"» ver aus Schalen tropischer Nüsse in die üblichen Lackgrund» stoffe eingebracht wird. Der dadurch erhaltene Lack zeichnet sich dadurch aus, daß in den üblichen Läckgrund$to£fen ein für die Berührung von Schleimhäuten und Halbachleimhlutan ?U|#- lassener unschädlicher organischer Farbstoff und Feinstpul¥$r aus Schalen tropischer Nüsse vorhanden ist. Die mit dieiem Lack hergestellte öherzugsschicht enthält dann neben eine» Gehalt von üblichen Lackgrundstoffen innerhalb von diesem Feinstpulvisr aus Schalen tropischer Früchte, vorzugsweise Mehl-auf Kokon <nußschalen, und organische Farbstoffe.The invention consists in the simultaneous use of organic approved for mucous membranes and semi-mucous membranes Coloring agents together with the flour or fine powder from the pods of tropical fruits. The lacquer is produced by that as a carrier for organic dyes flour or fine powder "» ver from shells of tropical nuts in the usual lacquer base » substances is introduced. The varnish thus obtained is distinguished by the fact that a pot is poured into the usual Läckgrund for touching mucous membranes and Halbachleimhlutan? U | # - non-harmful organic dye and fine powder from shells of tropical nuts. The ones with the paint The additional layer produced then contains, in addition to a »content of common paint base materials within this fine powder from shells of tropical fruits, preferably flour on cocoon <nutshells, and organic dyes.

Die erhaltene Übersugsschicht kann auch selbsttragend sein, d.h. sie braucht nicht von- einer Papiers chi ent getragen zu sein, sondern sie kann eine selbständige Folie bilden.The obtained overlay can also be self-supporting, i.e. it does not need to be carried by a piece of paper, but it can form an independent film.
Die Verwendung' von Feinstpulver aus Schalen tropischer Früchte ist von der Arme leerin bereits in älteren Anmeldungen' vorgeschli 5tn worden. Dort ist die Erzielung einer bestimmten Überflächenrauhigkeit durch die Verwendung dieses Feinstpulvers beschrieben. Die dort ebenfalls beschriebene Hinfärbung1erfolgte jedoch lediglich mit oisher bereits bekannten anorganischen Färbemitteln, wie sie seit eh und je für die Färbung derartiger Lacke in der.beschriebenen nachteiligen Weise benutzt werden. The use of "fine powder from the peel of tropical fruits" has already been suggested by the poor in earlier applications. There the achievement of a certain surface roughness through the use of this very fine powder is described. The coloration 1 also described there, however, was carried out only with inorganic colorants already known, such as have always been used for the coloration of such paints in the disadvantageous manner described.
Die Verwendung von organischen Farbstoffen erschien aufgrund der jahrelang mißglückten Versuche zur Zeit der äteren Vorschläge der Verwendung von Feinstmehl aus Schalen tropischer Früchte nicht erfolgversprechend. Die vorliegende Erfindung hat sich über dieses Vorurteil hinweggesetzt und damit erhebliche Vorteile erreicht: Bisenoxyd zur ßraunfärbung kann völlig entfallen. Die organischen Farbstoffe brauchen nur in kleinsten Mengen zugesetzt zu werden, da sich das Feinstpulver tropischer Fruchtschalen als hervorragender Farbträger herausgestellt hat.The use of organic dyes appeared due of the unsuccessful attempts for years at the time of the older proposals the use of fine flour from the peels of tropical fruits is not promising. The present invention has defied this prejudice and thus achieved considerable advantages: Bisenoxide for browning can completely omitted. The organic dyes only need to be added in very small quantities, as the finest powder tropical fruit peels has proven to be an excellent color carrier.

Die Stückchen 3 des Pulvers tropischer Nußschalen wirken hier als Farbstoffträger und auch als Reflektoren, so daß schon mit ganz geringen Mengen des organischen Farbstoffes beträchtliche Linf.ärbungen erzielt werden.2 and from the finest pieces 3 of the powder of tropical nutshells is made.
