Description
Kinefilm mit Tonstreifen Die Erfindung bezieht sich auf einen Kinefilm mit einem Tonstreifen, der aus einer Mischung besteht, die ein körniges, ferromagnetisches Material und ein Bindemittel enthält, auf dem während der photographischen Belichtung Tonaufzeichnungen erfolgen können.Motion picture film with sound strips The invention relates to a motion picture film with a clay strip that consists of a mixture that is a granular, ferromagnetic Contains material and a binder on which during photographic exposure Sound recordings can be made.
Der Erfindung lag die Aufgabe zugrunde, einen Kinefilm mit einem Tonstreifen zu schaffen, der während und nach der Belichtung rnagnetisierbar ist und gegenüber photographischen Entwicklungs-und üblichen Reinigungsverfahren beständig ist und nicht entfernt werden kann.The invention was based on the object of providing a motion picture film with a sound strip to create that is magnetizable during and after exposure and opposite photographic development and usual cleaning processes is stable and cannot be removed.
Der Erfindung lag die Erkenntnis zugrunde, daß der Tonstreifen auf dem Kinefilm beständig verankert werden kann, wenn die Tonstreifenmischung ein bestimmtes Arnid enthält. Der Kinefilm der Erfindung ist daher dadurch gekennzeichnet, daß die Mischung, aus der der Tonstreifen besteht, zusätzlich ein, niederes N,N-Dialkylamid einer aliphatischen Säure enthält.The invention was based on the knowledge that the clay strips on the motion picture film can be permanently anchored if the sound strip mix a certain Contains arnid. The motion picture film of the invention is therefore characterized in that the mixture of which the clay strip consists, in addition, a, lower N, N-dialkylamide contains an aliphatic acid.
Als besonders vorteilhaft hat es sich erwiesen, wenn der magnetische Tonstreifen auf dem Kinelilm durch Auftragen einer Mischung, bestehend aus Bindemittel, ferromagnetischern Material und einem in einem Lösungsmittelgemisch gelösten N,N-Dialkylamid über der Lichthofschutzschicht eines sensibilisierten photographischen Filmes erzeugt wird. Das N,N-Dialkylamid löst dann einen Teil der Lichthofschutzschicht und verankert den magnetischen Tonstreifen sicher auf dem Filmträger.It has proven to be particularly advantageous if the magnetic Clay strips on the Kinelilm by applying a mixture consisting of binding agent, ferromagnetic material and an N, N-dialkylamide dissolved in a solvent mixture generated over the antihalation layer of a sensitized photographic film will. The N, N-dialkylamide then dissolves part of the antihalation layer and anchors it the magnetic sound strip securely on the film carrier.
Die Lichthofschutzschichten enthalten als Bindemittel gewöhnlich ein wasserunlösliches, alkalilösliches, synthetisches, kolloides Polymer, z. B. einen Celluloseester oder ein synthetisches Harz. Besonders oft verwendet werden Celluloseester, die aus Dicarbonsäureestern von Cellulose bestehen, z. B. aus Celluloseacetatphthalat, Celluloseacetatmaleat, Celluloseacetatsuccinat, Celluloseacetatpropionatphthalat, Celluloseacetatpropionatmaleat oder Cel l uloseacetatpropionatsuccinat.Oft verwendete synthetische Harze sind beispielsweise Polyvinylharze, wie Polyvinylphthalat und Polyvinylaeetatphthalat.The antihalation layers usually contain one as a binder water-insoluble, alkali-soluble, synthetic, colloidal polymer, e.g. B. a Cellulose ester or a synthetic resin. Cellulose esters are used particularly often, which consist of dicarboxylic acid esters of cellulose, e.g. B. from cellulose acetate phthalate, Cellulose acetate maleate, cellulose acetate succinate, cellulose acetate propionate phthalate, Cellulose acetate propionate maleate or cellulose acetate propionate succinate. Often used synthetic resins are, for example, polyvinyl resins such as polyvinyl phthalate and Polyvinyl acetate phthalate.
Besonders geeignete N,N-Dialkylamide sind beispielsweise N,N-Dirnethylforniamid, N,N-Dimethylacetamid und N,N-Diäthylformamid.Particularly suitable N, N-dialkylamides are, for example, N, N-dirnethylforniamide, N, N-dimethylacetamide and N, N-diethylformamide.
Vorzugsweise liegt das N,N-Dialkylamid in der Mischung in einem Anteil von 'a bis 22 Gewichtsprozent vor. Die verwendeten Lösungsmittel sollen mit dein Bindemittel verträglich sein, und mindesten eines der Lösungsmittel des Lösungsmittelgernische6 soll die Lichthofschutzschicht lösen können- um den Filmträger zu erreichen, wo sie den Tonstreifen wirksam verankern.Preferably the N, N-dialkylamide is in one portion in the mixture from a to 22 percent by weight. The solvents used should be compatible with your Binder compatible, and at least one of the solvents of the solvent mixture6 should be able to loosen the antihalation layer - to reach the film carrier, where they effectively anchor the clay strip.
Der Tonstreifenmischung können gegebenenfalls Farbstoffe, wie z. B. Malachitgrün, zugesetzt werden, um die Kenntlichmachung des Streifens zu erleichtern.The clay strips mixture can optionally dyes, such as. B. Malachite green, can be added to make the stripe easier to identify.
Geeignete filmbildende Bindemittel sind beispielsweise Cellulose und deren Abkömmlinge sowie Polymerisationsprodukte, wie Polyvinylchlorid und Polyvinylacetat, Polyacrylverbindungen oder Kondensationsprodukte, wie sie z. B. durch Kondensation von mehrwertigen Alkoholen mit mehrwertigen organischen Säuren erhalten werden. Geeignet sind ferner Natur- und Kunstkautschuk, Polyamide, Polyester, Polyolefine, Polyvinylacetale, Methylmethacrylatharze und Polyurethane. Besonders geeignet sind Cellulosenitrate, die in Aceton zu klaren viskosen Lösungen gelöst werden können.Suitable film-forming binders are, for example, cellulose and their derivatives and polymerization products such as polyvinyl chloride and polyvinyl acetate, Polyacrylic compounds or condensation products, as they are, for. B. by condensation from polyhydric alcohols with polybasic organic acids. Also suitable are natural and synthetic rubber, polyamides, polyesters, polyolefins, Polyvinyl acetals, methyl methacrylate resins and polyurethanes.

Die folgenden Beispiele sollen die Erfindung näher veranschaulichen. Beispiel 1 Es wurde eine magnetische Tonstreifenmischung folgender Zusammensetzung hergestellt: Cellulosenitratansatz . . . . . . . . . . . . . 640 g Äthylenglyköl . . . . . . . . . . . . . . . . . . . 28 g 2-Butoxyäthanol ................. 200 g N,N-Dimethylformamid . . . . . . . . . . 200 g Magnetisches Eisenoxyd . . . . . . . . . . 320 g Diese magnetische Tonstreifenmischung wurde auf einen Teil einer Lichthofschutzschicht aufgetragen, mit der ein Cellulosetriacetatfilmträger beschichtet war. Die Lichthofschutzschicht enthielt ein alkalilösliches, aus Celluloseacetatphthalat bestehendes Bindemittel.The following examples are intended to illustrate the invention in more detail. Example 1 A magnetic clay strip mixture of the following composition was produced: Cellulose nitrate batch. . . . . . . . . . . . . 640 g ethylene glycol. . . . . . . . . . . . . . . . . . . 28 g of 2-butoxyethanol ................. 200 g of N, N-dimethylformamide. . . . . . . . . . 200 g of magnetic iron oxide. . . . . . . . . . 320 g of this magnetic clay tape mix was applied to a portion of an antihalation layer coated on a cellulose triacetate film base. The antihalation layer contained an alkali-soluble cellulose acetate phthalate binder.
Wird der Film in eine alkalische Entwicklerlösung getaucht, so wird die von dem Tonstreifen nicht bedeckte Lichthofschutzschicht gelöst. Der Tonstreifen haftet jedoch fest am Träger. Wird auf den magnetischen Tonstreifen ein Klebeband aufgebracht, so bleibt der Tonstreifen auf dem Träger haften, wenn das Klebeband schnell abgezogen wird.If the film is immersed in an alkaline developing solution, then the antihalation layer not covered by the clay strip was released. The clay strip however, adheres firmly to the carrier. Adhesive tape will be attached to the magnetic sound strip When the tape is applied, the tape will stick to the backing is withdrawn quickly.
Beispiel 2 Eine Tonstreifenmischung der im Beispiel l beschriebenen Zusammensetzung wurde auf die mit einer Lichthofschutzschicht bedeckte Oberfläche eines Cellulosetriacetatfilmträgers aufgebracht. Eine Farbemulsion vom subtraktiven Typ wurde auf die andere Seite des Trägers aufgebracht. Der erhaltene Film wurde in einer Kamera belichtet, die während der Belichtung des Filmes auch den Ton aufzeichnete. Der Farbfilm wurde dann in einem für die Entwicklung von Farbfilmen üblichen Entwickler entwickelt. Die Tonspur haftete nach dem Entwickeln fest am Film an. Nach dem Entwickeln wurde die Tonwiedergabe überprüft. Es zeigte sich, daß die Qualität der Tonspur der Qualität solcher Tonspuren entsprach, die nach dem Entwickeln auf einen Film aufgebracht werden.Example 2 A clay strip mix of those described in Example 1 Composition was applied to the surface covered with an antihalation layer applied to a cellulose triacetate film backing. A color emulsion from the subtractive Type was applied to the other side of the backing. The obtained film became exposed in a camera that also recorded the sound during the exposure of the film. The color film was then placed in a developer common for color film development developed. The sound track adhered firmly to the film after development. After developing the sound reproduction has been checked. It turned out that the quality of the soundtrack corresponded to the quality of such soundtracks after being developed onto film be applied.
