Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass plate color transfer method.

[0002]

2. Description of the Related Art It has been well known that, in order to obtain colored glass for construction or decoration, the surface of a glass plate is colored with an organic paint or an inorganic pigment to finish it in, for example, a stained glass tone. However, if the glass plate surface is simply colored by the above-mentioned organic paint or the like, not only the external action such as temperature change, water drop or friction, but also the inside of the color collecting part, particularly the glass plate surface and the glass plate surface The internal effect caused by the bubbles that are present between the back surface of the color part facing the color part and the back surface of the color part causes the color part to deteriorate and the color part to deteriorate. There was a problem that it was difficult to extend the number of years. Further, when forming the colored portion on the surface of the glass plate, various colors are sequentially placed from the surface side of the glass plate to finish only the surface of the colored portion into a desired pattern. The surface facing the plate) was in a state where the colors were randomly overlapped, and when viewed from the back side of the glass plate, it was far from the beautiful form on the front side of the glass plate, which was extremely unsightly. Therefore, it is extremely difficult to make a desired pattern stand out on both sides of the glass plate, and it is difficult to improve the aesthetic value of the glass plate.

[0003]

In view of the above problems,
It is an object of the present invention to provide a glass plate color transfer method capable of exhibiting a small aging change of a colored portion and exhibiting the same aesthetic appearance from both front and back surfaces of the glass plate.

[0004]

In order to achieve the above-mentioned object, the present invention provides a glass plate color transfer method in which, as a first invention, an ultraviolet ray non-reactive coloring transferred to a film under vacuum or substantially vacuum. Part, and an ultraviolet curable liquid thin film applied to the surface of the glass plate are polymerized, the thin film is irradiated with ultraviolet rays to cure the thin film, the atmospheric pressure is raised, and the film is peeled from the colored part. Technology and, as a second invention, under vacuum or substantially vacuum, one surface of the UV-insensitive coloring portion transferred to the film and the UV-curable liquid thin film applied to the surface of the first glass plate are polymerized. Then, the thin film is irradiated with ultraviolet rays to cure the thin film to raise the atmospheric pressure, and the film is peeled from the colored portion,
Moreover, under vacuum or substantially vacuum, the other surface of the colored portion and the ultraviolet curable liquid transparent thin film applied to the surface of the second glass plate are polymerized, and the thin film is irradiated with ultraviolet rays to form the thin film. The technology of hardening the air and raising the atmospheric pressure,
As a third invention, the first invention or the second invention is constituted by adopting a technique of adopting a transparent film having a color collecting portion transferred by photolithography.

[0005]

Embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the colored portion 4 is transferred to the transparent film 3 by photolithography. If desired, the coloring section 4 can
It can be in the form of letters, patterns, or the like. Further, the ultraviolet curable liquid transparent thin film 2 is uniformly applied to the glass plate 1. The thin film 2 is, for example, a liquid monomer or oligomer in which an acrylic resin-based one such as oligoacrylate, epoxy acrylate, urethane acrylate, silicon acrylate, and spiran acrylate is used as a main component and a benzophenone compound is added as a photosensitizer. Is preferred. The colored portion 4 and the thin film 2 are polymerized under vacuum and are irradiated with ultraviolet rays as shown in FIG. By doing so, the photosensitizer is decomposed and the acrylate is polymerized and cured. At this time, if the temperature is set to 60 ° C. to 100 ° C., the thin film 2 is cured in several seconds to several tens of seconds. Next, when the vacuum state is released and the atmospheric pressure is improved to reach the atmospheric pressure, the atmospheric pressure presses the transparent film 2, and the colored portion 4 is integrated with the surface of the glass plate 1 without intervening air. . Then, as shown in FIG. 3, when the transparent film 3 is peeled from the colored portion 4, the colored portion 4 appears on the glass plate 1. Further, as shown in FIGS. 4 to 6, a thin film 2 similar to the above is applied to the surface of the other glass plate 1, and the thin film 2 and the colored portion 4 are polymerized under vacuum to emit an ultraviolet ray 5. After irradiation, the atmospheric pressure is raised to atmospheric pressure. In this way, the colored portion 4 is sandwiched and polymerized between the two glass plates 1 and 1 without containing bubbles or the like, and is applied to the colored portion 4 from any of the glass plates 1 and 1. The morphology emerges, and the front and back surfaces of the glass plates 1 and 1 have the same aesthetic appearance. Needless to say, since the glass plate 1 has high hardness and good acid resistance, the colored portion 4 is protected from deterioration factors such as bubbles, water droplets, friction, etc., and must be prevented from discoloring or fading for many years. You can Of course, the present invention is not limited to the above embodiment,
Various modifications can be made as necessary without changing the gist of the invention.

[0006]

EFFECT OF THE INVENTION The present invention is constructed as described above, and it is possible to remove factors causing aging from the colored portion, such as bubbles, and the colored portion is protected by a glass plate having good hardness and acid resistance. It is possible to transfer colors with minimal changes over time in the colored part. Moreover, since the colored portion is transferred to the film, the same aesthetic appearance can be exhibited from both the front and back surfaces of the glass plate, and the aesthetic value of the glass plate can be improved. Further, since the liquid crystal transparent thin film curable with ultraviolet rays is adopted, the color can be transferred at a low cost without the need for an electron beam irradiation device.
