The present invention relates to a film structure and a method of manufacturing the same, and more particularly to a film structure having both fluorescent and luminous properties and a method of manufacturing the same.

Generally, the luminous materials are made of light yellow-green powder (green light) with white light characteristics, white powder (blue light), and other colors of pigments, inks, etc. Although the body color of the luminous materials on the market now has colors such as blue, green, orange, red, etc., the colors are all biased towards pale pink tones, and the colors of the luminous colors are the same as those of the body itself. of. In addition, the night light and the fluorescent color itself are counteracted, because the characteristics of the fluorescent light will absorb the light of the night light, resulting in the loss of the original luminous effect.

In other words, the color of the currently commercially available luminous powder body is still monotonous, the color of the body and the luminous light are consistent, and the fluorescent and luminous light cannot coexist.

In view of this, the present invention provides a film junction having both fluorescent and luminous characteristics.

The present invention is described with reference to the accompanying drawings, which are illustrated in the accompanying drawings, but the invention may be practiced in various forms and should not be construed as being limited to the embodiments described herein. In the drawings, the dimensions and relative dimensions of the various components or layers may be exaggerated for clarity.

Herein, when a component or layer is referred to as being "on another component or layer", it may be directly on the other component or layer or the intermediate component or layer may be present. The spatially relative terms used in the text such as "under", "on", and the like, are used to describe the relationship of the components or layers described in the figures to another. Such spatially relative terms shall include components in use or operation, and include different orientations other than those depicted in the Figures. For example, if a component in the drawings is turned over, it is described as being "on" another member or layer.

In this paper, the main component of the term "fluorescent powder" is a material containing a fluorescent chromophore, which absorbs light after being exposed to natural light, daylight, ultraviolet light, etc. After entering the excited state, it immediately retreats and emits the emitted light (usually the wavelength is longer than the wavelength of the incident light in the visible light band); and once the incident light is stopped, the luminescence disappears immediately. Fluorescent powders come in a variety of colors and emit the same fluorescent color as fluorescent powder during the day, and do not develop color at night.

In this paper, the term "night light particles" or "long-lasting luminous particles" refers to photo-storage luminous powder, whose main component is a material including rare earth elements. After being exposed to natural light, daylight, ultraviolet light, etc., The light energy is stored and released slowly in the form of night light after stopping the light irradiation, so that at night or in the dark, the light can still be seen for a duration of several hours to ten hours. The luminous particles are mostly light or light-colored powders, which do not develop color during the day, and emit night light of the same color as the luminous particles at night.

FIG. 1 is a cross-sectional view showing a film structure having both fluorescent and luminous characteristics according to an embodiment of the invention. 2 is a flow chart showing a method of fabricating a film structure having both fluorescent and luminous characteristics according to an embodiment of the invention.

Referring to FIG. 1 and FIG. 2, step 100 is performed to provide a transparent substrate 10. The material of the transparent substrate 10 includes a transparent plastic material such as polycarbonate (PC), polyethylene terephthalate (PET), polyphenylene ether (PES), polymethyl methacrylate (PMMA), and the like.

Next, in step 102, the luminous ink layer 12 is formed on the backlight surface 10b of the transparent substrate 10. First, the luminous ink is modulated, and the step is to use long-lasting luminous particles. The neutral and alkaline transparent ink is uniformly prepared by stirring in a specific ratio of 20% to 50% (for example, 50%), and an anti-settling agent (i.e., a dispersing agent) is added thereto to make it long. The luminous particles can be more uniformly mixed into the ink. Next, the prepared luminous ink was screen-printed onto the transparent substrate 10 using an 80-mesh screen, and the printing was repeated and sequentially stacked two or more times to form the luminous ink layer 12 on the transparent substrate 10.

Next, the prepared fluorescent ink screen is printed onto the luminous ink layer 12 by 120-mesh screen printing, and the printing is repeated and sequentially stacked two or more times to form the fluorescent ink layer 14 on the luminous ink layer 12. The luminous ink layer 12 and the fluorescent ink layer 14 constitute the stacked layer 13 of the present invention.

In one embodiment, the thickness of the luminous ink layer 12 is greater than the thickness of the fluorescent ink layer 14. Specifically, the thickness ratio of the luminous ink layer 12 to the fluorescent ink layer 14 is about 3:1 to 1:1 (for example, 3:1). For example, the thickness of the luminous ink layer 12 is about 6 to 9 μm, and the thickness of the fluorescent ink layer 14 is about 2 to 3 μm. In another embodiment, the thickness of the luminous ink layer 12 can also be less than the thickness of the fluorescent ink layer 14.

Thereafter, in step 106, a light reflecting layer 16 is formed on the fluorescent ink layer 14. The reflective layer 16 can be a white or reflective base color to increase brightness and illumination time. The material of the reflective layer 16 includes printing ink or retroreflective sheeting.

Then, in step 108, an adhesive layer 18 is formed on the reflective layer 16. The purpose of the adhesive layer 18 is to allow the subsequently cut film structure pattern to be directly adhered to the surface of the product. Thus far, the film structure 1 of the present invention having both fluorescent and luminous characteristics has been completed.

It is particularly noted that the fluorescent material emitted by the membrane structure 1 of the present invention is different in color from the night light, that is, the color displayed during daytime and nighttime. Specifically, this In the film structure 1 of the invention, the fluorescent light emitted during the day is the color of the fluorescent ink layer 14, and the night light emitted at night is the mixed color of the luminous ink layer 12 and the fluorescent ink layer 14.

In one embodiment, as shown in Table 1, the color of the luminous ink layer and the fluorescent ink layer may be selected such that the film structure of the present invention emits different colors during daytime and nighttime, as shown by samples Nos. 1-10. .

In particular, in order to make the fluorescent light and the night light coexist and avoid mutual interference, the color of the body is diversified and lively, and the luminous effect is not affected, so the environment of the ink modulation, the fluorescent night light The corresponding color, luminous powder and ink, the composition and proportion of the phosphor and ink, the printing order, the number of times, the mesh, etc., can be adjusted according to the needs of the user. In other words, Table 1 above The fluorescent and luminous colors emitted by the samples of numbers 1 to 10 are for illustrative purposes only and are not intended to limit the invention. According to customer's requirements, a film structure with any fluorescent and luminous color effects to be displayed can be prepared.

Next, in step 110, the film structure 1 is cut to obtain a film structure pattern of a desired shape. The cutting step is, for example, using a CNC cutter. The shape of the membrane structure can be triangular, circular, elliptical, donut, lucky grass, flower, love, strawberry, star, crescent moon, polygon, lip, English alphabet, Chinese characters, various custom shapes, and the like. The membrane structure of the present invention can be used in a variety of applications and applications, such as craft decoration, stage props, star painting, traffic signs, prints, escape routes in public places, and the like.
