Abstract

In order to make a decoration on a glass or dial of a measuring instrument, for example a wristwatch, a photosensitive layer is used to define the shape, onto which the design of the decoration is optically transferred. As a result, it is possible to make decorations with a very fine engraving and sharp contours, so that, for example, photographs and half-tones can also be applied.

Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Dekors an einem Glas, Gehäuse oder Zifferblatt, wobei insbesondere an Uhrengläser, Uhrengehäuse und Zifferblätter von Armbanduhren gedacht ist.The present invention relates to a method for producing a decoration on a glass, case or dial, in particular with watch glasses, watch cases and dials of wristwatches.

Ein wichtiger Schritt bei der Herstellung von Dekors, beispielsweise an einem Zifferblatt einer Digital-Armbanduhr ist die Herstellung der Konturen auf der Unterlage, nach welchen das Dekor aus einer Schicht entweder herausgeätzt oder die Dekorschicht aufgalvanisiert wird. Für die Herstellung einfacher Formen genügt eventuell das Siebdruckverfahren oder das Farbdruckverfahren. Für das Herstellen von genaueren und komplizierteren Formen hat sich das Umdruckverfahren eingebürgert. Dieses Umdruckverfahren ist jedoch immer noch relativ grob und erlaubt daher keine Dekorschicht mit feiner Rasterung.An important step in the production of decorations, for example on a dial of a digital wristwatch, is the production of the contours on the base, according to which the decor is either etched out of a layer or the decor layer is electroplated. The screen printing process or the color printing process may suffice for the production of simple shapes. The transfer printing process has become established for the production of more precise and complicated forms. However, this transfer printing process is still relatively coarse and therefore does not allow a decorative layer with fine screening.

Es ist daher Aufgabe der vorliegenden Erfindung ein Verfahren anzugeben, mittels welchem es möglich ist, Dekorschichten mit grosser Feinheit und feiner Rasterung herzustellen. Das Verfahren, das diese Aufgabe löst, wird in den Ansprüchen beschrieben.It is therefore an object of the present invention, a V indicate learn by means of which it is possible to produce decorative layers with great delicacy and fine screening. The method that solves this problem is described in the claims.

Die Erfindung wird nun im folgenden anhand von Ausführungsbeispielen näher erläutert. Die Erfindung beruht auf der Erkenntnis, dass die Verwendung einer lichtempfindlichen Schicht, eines sog. Photolacks und einer op- tischen Uebertragung einer Vorlage auf diese lichtempfindliche Schicht, eine bis dahin nicht gekannte Feinheit der Dekorschicht ermöglicht und somit neue Dekorationsmöglichkeiten an Uhrengläsern und Zifferblätter eröffnet. Die Verwendung von lichtempfindlichen Schichten zur Erzielung von sehr feinen Mustern ist insbesondere aus der Halbleiterindustrie bekannt, d.h. zur Herstellung von integrierten Schaltungen, doch werden dort infolge der noch grösseren Feinheit und notwendigen Genauigkeit und Komplexität der Schaltungen sehr hohe Anforderungen an die Optik und an die Aetztechnik gestellt. Bei der Verwendung einer lichtempfindlichen Schicht für Dekorationszwecke kann eine viel geringere Anforderung an die Uebertragungsoptik gestellt werden, während die Gestaltungsmöglichkeiten im Vergleich zu den bisher bekannten Verfahren zur Herstellung von Dekorschichten wesentlich vergrössert werden.The invention will now be explained in more detail below with the aid of exemplary embodiments. The invention is based on the finding that the use of a photosensitive layer, a so-called photoresist and an op -. Tables transmission enables an original on this photosensitive layer, a hitherto unknown fineness of the decor layer and thus opens up new possibilities of decoration to watch glasses and dials. The use of light-sensitive layers to achieve very fine patterns is known in particular from the semiconductor industry, ie for the manufacture integrated circuits, but due to the even greater fineness and the necessary accuracy and complexity of the circuits, very high demands are placed on the optics and on the etching technology. When using a light-sensitive layer for decorative purposes, much less demands can be placed on the transmission optics, while the design options are significantly increased compared to the previously known methods for producing decorative layers.

In einem ersten Ausführungsbeispiel wird zuerst die geschlossene Dekorschicht, beispielsweise aus metallischen Materialien wie Gold, Nickel, Chrom, Schwarzchrom oder aus Metalloxyden oder sonstigen organischen oder mineralischen Materialien oder aus einer Schicht mit einem anderen Brechungsindex für das Licht als die Unterlage, dann wird die lichtempfindliche Schicht aufgebracht und durch eine oder mehrere Masken mit Hilfe einer relativ einfachen Optik belichtet, wonach durch Entwickeln die lichtempfindliche Schicht formgenau entfernt wird. Daraufhin wird die nicht mehr mit Photolack geschützte Dekorschicht chemisch oder mechanisch entfernt. Es kann aber auch so verfahren werden, dass zuerst die lichtempfindliche Schicht aufgetragen, belichtet und entwickelt wird und anschliessend auf die nicht mehr gedeckten Stellen die Dekorschicht aufgetragen wird. Die beiden genannten Verfahren können mehrmals wiederholt und auch kombiniert werden, wobei die Dekorschichten aus verschiedenen Materialien und Farben bestehen können.In a first embodiment, the closed decorative layer, for example made of metallic materials such as gold, nickel, chromium, black chrome or metal oxides or other organic or mineral materials or a layer with a different refractive index for the light than the base, is then the photosensitive Layer applied and exposed through one or more masks with the aid of a relatively simple optics, after which the photosensitive layer is removed by developing the shape. The decorative layer, which is no longer protected with photoresist, is then removed chemically or mechanically. However, it can also be done in such a way that the light-sensitive layer is first applied, exposed and developed and then the decorative layer is applied to the areas which are no longer covered. The two processes mentioned can be repeated and also combined several times, the decorative layers being able to consist of different materials and colors.

Durch die Verwendung von lichtempfindlichen Schichten und einer Optik zur Gestaltung der Form auf der lichtempfindlichen Schicht ist es möglich, Halbtöne und Schattierungen mittels Lochrasterungen und mindestens einer hellen und einer dunklen Farbe zu erzeugen, wobei selbstverständlich auch mehrere Farben verwendet werden können. Es ist aber auch möglich, eine Vorlage, beispielsweise eine Fotografie oder sonst ein Bild auf die Fotoschicht und somit auf die Dekorschicht zu übertragen. Mit diesem Verfahren ist es möglich, Dekors in Form von Zeichen, Ziffern, Zahlen oder Strichen auf ein Uhrenglas aus Mineralglas, Saphir oder Kunststoff aufzubringen, wobei es selbstverständlich auch möglich ist, die Dekors auf beiden Seiten des Glases anzubringen. Das gleiche gilt auch für andere Messinstrumente oder Bordinstrumente von Fahrzeugen wie Automobile und Flugzeuge. Es ist aber auch möglich, Dekors auf Zifferblätter anzubringen, die auch aus Glas, Saphir oder Kunststoff angefertigt sind. Wie bereits weiter oben erwähnt, ist es auch möglich, am Glas als Dekorschicht eine Schicht mit einem anderen Brechungsindex als das Glas oder die umgebende Antireflexschicht anzubringen.By the use of light-sensitive layers and an optical system for designing the shape of the photosensitive layer, it is possible, half-tones and Schattierun g en by means of grids of holes and at least one light and to produce a dark color, whereby of course also uses multiple colors can. However, it is also possible to transfer a template, for example a photograph or some other image, to the photo layer and thus to the decorative layer. With this method it is possible to apply decorations in the form of characters, numbers, numbers or lines to a watch glass made of mineral glass, sapphire or plastic, whereby it is of course also possible to apply the decorations on both sides of the glass. The same also applies to other measuring instruments or on-board instruments of vehicles such as automobiles and airplanes. However, it is also possible to apply decorations to dials that are also made of glass, sapphire or plastic. As already mentioned above, it is also possible to apply a layer with a different refractive index to the glass as a decorative layer than the glass or the surrounding antireflection layer.

Es ist auch möglich, eine solche Dekorschicht auf ein Gehäuse anzubringen.It is also possible to apply such a decorative layer to a housing.
