Description

Mehrzonenfarbfilter für die Wiedergabe von Linsenrasterfilmen Zusatz zum Patent 641 550 Gegenstand des Hauptpatents ist ein Mehrzonenfarbfilter für die Wiedergabe von Linsenrasterfilmen, bei :dem die Zonen verschiedener Farbe derart aus verschiedenartigem Material gebildet werden, daß ein Teil der Zonen aus weichem Material (z. B. Gelatine, Kollodium), der andere Teil aus hartem Material (z. B. Glas, Quarz) besteht. In der Praxis hat es sich ergeben, ,daß beispielsweise die eine Farbe auf dem einen Material lichtbeständiger ist, während die andere Farbe auf ,dem anderen Material größere Dauerhaftigkeit besitzt.Multi-zone color filter for the reproduction of lenticular lenticular films Addendum to patent 641 550 The subject of the main patent is a multi-zone color filter for the reproduction of lenticular lenticular films, in which the zones of different colors are formed from different material in such a way that some of the zones are made of soft material (e.g. Gelatine, collodion), the other part is made of hard material (e.g. glass, quartz). In practice it has been found that, for example, one color is more lightfast on one material, while the other color has greater durability on the other material.

Gemäß,der Erfindung soll nun eine weitere Verbesserung eines Mehrzonenfarbfilters durch weitere günstigste Anpassung des Filtermaterials an die entsprechende Farbe geschaffen werden, indem ein Teil der Zone aus einem Flüssigkeitsfilter gebildet wird. Flüssigkeitsfilter sind unter gewissen Umstünden besonders günstig für die blaue Zone, wobei noch der vorteilhafte Umstand auftritt, daß bei Verwendung einer starken Projektionslichtquelle, z. B. einer Bogenlampe, das Filter nicht durch die entstehende Hitze angegriffen wird.According to the invention, there is now a further improvement to a multi-zone color filter by further advantageous adaptation of the filter material to the corresponding color can be created by forming part of the zone from a liquid filter will. Liquid filters are particularly beneficial for the under certain circumstances blue zone, with the advantageous fact that when using a strong projection light source, e.g. B. an arc lamp, the filter not through the the resulting heat is attacked.

Beispielsweise kann ein Filter gemäß .der vorliegenden Erfindung derartig ausgebildet werden, daß die blaue Zone aus Flüssigkeit, die rote Zone aus Glas und die grüne aus Gelatine gebildet wird.For example, a filter according to the present invention can be such be formed that the blue zone of liquid, the red zone of glass and the green one is formed from gelatin.
