Description
Verfahren zum Herstellen von Gießunterlagen für Linsenrasterfilme Gegenstand des Hauptpatents ist ein Verfahren zum Herstellen von Prägewalzen zum Prägen von Linsenrasterfilmen oder Gießunterlagen für Linsenrasterfilme, wobei .eine Walze mit einer lichtempfindlichen Schicht überzogen und darauf das Raster auf photographischem Wege als gehärtetes Relief erzeugt wird. Mit Hilfe dieses Prägezylinders wird der Film selbst oder die Gießunterlage geprägt, zweckmäßig bei höherer Temperatur. Gegebenenfalls wird der Film oder die Unterlage mit Lösungs-oder Quellungsmittteln vorbehandelt.Process for making cast bases for lenticular lenticular films The main patent is a method for producing embossing rollers for Embossing of lenticular films or casting bases for lenticular films, where .ein Roller covered with a photosensitive layer and on it the grid on photographic Paths is created as a hardened relief. With the help of this embossing cylinder, the The film itself or the casting base is embossed, expediently at a higher temperature. Possibly the film or the substrate is pretreated with solvents or swelling agents.
Es wurde nun gefunden, daß es vorteilhaft ist, die Gießunterlage aus Celluloseestern oder Celluloseäthern nach der Prägung zu verseifen. Das Verseifen geschieht mit Hilfe von stark alkalischen Lösungen. Hierdurch wird die Gießunterlage oberflächlich in regenerierte Cellulose übergeführt. Die so gebildete Oberfläche wird durch das Lösungsmittel der Lösung, aus der der Film gegossen wird, nicht angegriffen, so da,ß eine einwandfreie Abformung des Rasterreliefs möglich ist.It has now been found that it is advantageous to remove the casting pad To saponify cellulose esters or cellulose ethers after embossing. The saponification happens with the help of strongly alkaline solutions. This creates the casting pad superficially converted into regenerated cellulose. The surface thus formed is not attacked by the solvent of the solution from which the film is cast, so that a perfect impression of the grid relief is possible.
