[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a new color decoration for eyeglass frames, and more particularly, to a multi-layer color decoration for eyeglass frames that utilizes interference effects.

[0002]

[Prior art]

 Eyeglasses have an element as a fashionable tool, and there is a strong tendency to attach importance to fashionability. Among them, the surface treatment of spectacles has a remarkable effect on the design by directly appealing to human eyes, so many technologies such as vacuum deposition, sputtering, ion plating, plating, spraying of paint, and transfer printing are used. . However, since these techniques only apply a predetermined coloring material to the surface of the spectacles, the color tone of the obtained spectacles depends only on the color tone of the coloring material, and only a monotonous feeling can be obtained.

[0003]

[Problems to be solved by the device]

 Then, this invention makes it a technical subject to provide the surface decoration which shows a new color tone beyond the color tone of the material used for the surface decoration of eyeglasses.

[0004]

[Means for Solving the Problems]

 On the other hand, in the present invention, a predetermined first decorative layer is layered on the surface of the spectacle frame, and then the second decorative layer is vapor-deposited in the form of an interference thin film on the first decorative layer to form a multilayer type. It was decided to solve the above-mentioned problems by setting the decoration area. Of course, this decoration area does not have to be attached to the entire spectacle frame.

Since the second decoration layer formed by vapor deposition is laminated in a thin film shape, its color tone is affected to a large extent by the color of light that has passed through the film and reflected under the film. On the other hand, since the first decorative layer is arranged under the thin film, that is, the second decorative layer, the coloring of the decorative region is different from that of the first decorative layer alone and that of the second decorative layer alone. , The first decorative layer and the second decorative layer are mixed. Since the color development of the second decoration layer depends on the light interference phenomenon, the color of the material of the second decoration layer changes depending on the viewing angle. Further, the coloration of the decorative region depends on the amount of light reflected by the first decorative layer and transmitted through the second decorative layer. Therefore, there is also an effect that the amount of light transmitted through the second decorative layer changes and the color tone changes when the decorative region is viewed obliquely and when viewed from the front. Furthermore, since the vapor deposition method for forming the second decorative layer can adjust the thickness of the thin film, it is possible to change the coloration of the decorative region without changing the material for forming the first and second decorative layers. You can

It should be noted that the vapor deposition used for forming the second decorative layer includes a general vacuum vapor deposition method, a sputtering method, an ion plating method, a chemical vapor deposition method, and the like.

【Example】

 Hereinafter, the present invention will be described based on embodiments.

A spectacle frame base material 0a having a predetermined shape is made of nickel chrome alloy. An Au film is formed on the eyeglass frame base material 0a by a wet plating method. The Au coating is thick enough to hide the color of the base material 0a. After ultrasonically cleaning the plated eyeglass frame base material, a thin interference coating of magnesium fluoride is formed on the Au coating by vacuum deposition. The vacuum vapor deposition was performed by heating the evaporation source to 200 ° C. under a pressure of 5 × 10 ⁻³ Pascal. The Au coating layer thus formed becomes the first decoration layer 1a, and the vacuum vapor deposited MgF coating becomes the second decoration layer 2a. Also, unlike the metallic coating that adheres to the entire spectacle frame, the second decorative layer 2a formed by vacuum vapor deposition adheres only to the portion that was facing the evaporation source during vapor deposition, and this adhered portion becomes the decorative area A. . This decorative area A 1 has a color tone that is clearly different from the individual color tone of the first decorative layer 1a. In particular, the three-dimensional molding inherent in the spectacle frame naturally created parts with different viewing angles in the decorative area, resulting in a variety of graceful color tones. And this spectacle frame is provided with the decoration area | region which has different coloring from the 1st decoration layer and the 2nd decoration layer. An enlarged cross section of this decorative region is schematically shown in FIG.

In addition to the above, the vapor deposition material can be changed to silicon dioxide, zirconium oxide, titanium oxide, tantalum oxide, or the like. Further, when vapor deposition is performed while appropriately rotating the eyeglass frame, the vapor deposition layer spreads over the entire eyeglass frame.

Further, the first decorative layer can be changed to a resin film. For example, a transparent resin film is formed on the ophthalmic frame base material 0b made of nylon by a resin coating method to form the first decorative layer 1b, and after ultrasonic cleaning, aluminum is vacuum-deposited to form a second decorative layer like an interference film. 2b. In this case, the decorative region has a half-mirror-like silver color tone. The aluminum vapor deposition may be performed by heating the evaporation source to about 50 ° C. under a pressure of 5 × 10 ⁻³ Pascal. An enlarged cross section of this decorative region is schematically shown in FIG.

Furthermore, the first decorative layer can be changed to an ink film by transfer. An ink film of a predetermined color is transferred to the eyeglass frame base material 0c made of nylon to form the first decorative layer 1c. After ultrasonic cleaning, titanium oxide is vacuum deposited to form the second decorative layer 2c. The transfer of the ink film is performed by winding aluminum transfer paper coated with a sublimable ink around the eyeglass frame base material 0c and heating to sublime the ink. However, it is necessary to select an ink that does not completely sublimate the transferred ink film during the subsequent vacuum deposition. At the time of this transfer, for example, if a mosaic pattern of red ink and blue ink is transferred, the final decoration area is mainly the golden shine of the second decoration layer 2c and the red color of the first decoration layer 1c. The blue color has a mixed tone that changes depending on the angle. A schematic enlarged cross section of this decorative region is shown in FIG.

Further, a translucent resin film may be layered on the second decorative layer to form the third decorative layer. For example, using nylon for the eyeglass frame base material 0d, selecting a transparent resin film layered on the first decorative layer 1d by a resin coating method, and selecting a vacuum deposition layer of zirconium oxide for the second decorative layer 2d, and then selecting 2 A matting transparent resin film is layered on the decorative layer 2d to form a third decorative layer 3d. A resin coating method may be used for layering the third decorative layer 3d. At this time, the obtained decorative region of the spectacle frame has a color tone that gives a deep light to green. This third decorative layer 3d has a decorative effect as well as an effect of protecting the lower layer. A cross section of this decorative region is schematically shown in FIG.

When metal is used as the base material and the first decoration film is layered on the base material by plating, conductivity is ensured in the base material on which the first decoration film is layered. The second decorative layer may be deposited by the sputtering method or the ion plating method. It should be noted that when the vapor deposition method is used, it is easy to form a thin film, and the film thickness can be adjusted by changing the vapor deposition conditions and time. It is also possible to deposit the spots by using a masking technique. In addition to the above metals and metal oxides, there are many organic and inorganic substances that can be used as vapor deposition substances, so the range of color tone selection is wide.

[0014]

[Effect of device]

 According to the present invention, the thin second decorative layer is laminated on the first decorative layer, so that a decorative region having a special color tone which cannot be obtained by each layer alone can be obtained. Since the color tone of the decorative area changes depending on the angle, a new decorative effect different from the case of individual layers is expected. Further, since the vapor deposition method is used for the layering of the second decorative layer, a desired thin film can be easily obtained and the color tone can be changed by adjusting the film thickness. Thus, the present invention has high industrial utility value.
