Description

Technical Field

[0001] The utility model relates to the technical field of optical lettering films, in particular to a high-brightness black luminous lettering film. Background Art

[0002] Luminous text film is a film material with a luminous effect. It can be cut or engraved to create specific text or patterns that glow in the dark. The luminous powder in the film absorbs energy from an external light source and then emits a bright glow in low-light or dark environments, making the text or pattern clearly visible. This material is commonly used in advertising, signage, safety instructions, and personalized decorations, combining aesthetics with practicality.

[0003] Currently, the luminous writing films commonly used, particularly in the apparel sector, are generally light-colored. Darker luminous writing films, on the other hand, are extremely dim and fail to achieve the desired luminous effect. For example, black luminous writing films are in high demand in the market, but currently available black luminous writing films have weak luminescence and poor afterglow, making them difficult to meet user needs. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a high-brightness black luminous lettering film to solve the above problems.

[0005] The utility model adopts the following scheme:

[0006] The present application provides a high-brightness black luminous engraving film, comprising a protective film layer, a luminous layer, a translucent layer and a polyester hot-melt adhesive layer stacked from top to bottom; the protective film layer is configured to be transparent, and the translucent layer is configured to be black; the luminous layer is made of polyurethane; the transparent protective layer is formed on the top layer, and the black translucent layer is formed on the bottom layer, and translucent powder is added above the translucent film to reduce the covering of the luminous powder by the color powder in the translucent film.

[0007] As a further improvement, the luminous powder is evenly added into the luminous layer.

[0008] As a further improvement, the luminous powder has the same particle size.

[0009] As a further improvement, the particle size of the luminous powder is 250 mesh or 500 mesh.

[0010] As a further improvement, the color powder in the transparent film is a high-gloss black color.

[0011] As a further improvement, the thickness of the luminous layer is greater than the thickness of the protective film layer, and the thickness of the luminous layer is greater than the thickness of the shielding film.

[0012] As a further improvement, the thickness of the luminous layer and the polyester hot melt adhesive layer together accounts for at least 3 / 5 of the total thickness.

[0013] As a further improvement, the lower end surface of the polyester hot melt adhesive layer is configured as an uneven conical structure to increase its contact area.

[0014] As a further improvement, a release paper for easy peeling is provided below the polyester hot melt adhesive layer.

[0015] By adopting the above technical solution, the utility model can achieve the following technical effects:

[0016] 1. The high-gloss black luminous lettering film of the present application combines a black appearance with a luminous effect and lettering function to form a multi-layer composite film material. The top protective film layer is made transparent, and the black color layer is set on the bottom shielding layer, thereby reducing the covering of the color powder on the luminous powder, so that the luminous powder can fully absorb the light source.

[0017] 2. The luminous layer is made of polyurethane material and combined with evenly distributed luminous powder to ensure a high-brightness luminous effect in a dark environment and to last for a long time, which improves night recognition and safety. The top transparent protective film layer can effectively prevent damage to the film, such as rain, ultraviolet rays, scratches, etc., without affecting the luminous effect of the luminous layer, so that the engraving film has a longer service life.

[0018] 3. Adding luminous powder on the top of the transparent film effectively reduces the covering of the black color powder in the transparent layer on the luminous effect of the luminous powder, making the lettering film brighter at night and enhancing visibility. It also reduces the influence of the color powder on the absorption of light source after wrapping the luminous powder. Without affecting the covering of the bottom layer, a dark, high-gloss black luminous lettering film product with excellent luminous effect is produced. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example

[0024] Combine Figure 1 This embodiment provides a high-brightness black luminous lettering film, including a protective film layer 1, a luminous layer 2, a transparent layer 3 and a polyester hot melt adhesive layer 4 stacked from top to bottom.

[0025] The protective film layer 1 is transparent, the shielding layer 3 is black, and the luminous layer 2 is made of polyurethane.

[0026] The transparent protective layer is formed on the top layer, and the black shielding layer 3 is formed on the bottom layer. Luminous powder is added above the shielding film to reduce the covering of the luminous powder by the color powder in the shielding film.

[0027] The above-mentioned high-gloss black luminous lettering film combines the black appearance, luminous effect and lettering function to form a multi-layer composite film material. The top protective film layer 1 is made transparent, and the black color layer is set on the bottom shielding layer 3, thereby reducing the covering of the color powder on the luminous powder, so that the luminous powder can fully absorb the light source.

[0028] The luminous layer 2 is made of polyurethane material and combined with evenly distributed luminous powder to ensure a high-brightness luminous effect in a dark environment and can continue to glow for a long time, improving night recognition and safety. The top transparent protective film layer 1 can effectively prevent damage to the film, such as rain, ultraviolet rays, scratches, etc., without affecting the luminous effect of the luminous layer 2, so that the engraving film has a longer service life.

[0029] Adding luminous powder on top of the transparent film effectively reduces the covering of the black color powder in the transparent layer 3 on the luminous effect of the luminous powder, making the lettering film brighter at night, enhancing visibility, and reducing the influence of the color powder on the absorption of light source after wrapping the luminous powder. Without affecting the covering of the bottom layer, a dark, high-gloss black luminous lettering film product with excellent luminous effect is produced.

[0030] In this embodiment, the luminous powder is evenly added to the luminous layer 2. It should be mentioned that the high-brightness black luminous lettering film can emit bright light in the dark due to the evenly distributed luminous powder in the luminous layer 2, and the duration of the light depends on the absorbed light energy and the performance of the luminous powder.

[0031] Furthermore, the luminous powder has the same particle size. This consistent particle size distribution ensures that the luminous powder is evenly distributed within the luminous layer 2, thereby ensuring the consistency and stability of the luminous film's glow-in-the-dark effect. Light can be evenly emitted from all parts of the film, thus avoiding problems such as light spots or uneven brightness.

[0032] Preferably, the glow-in-the-dark powder has a particle size of 250 or 500 mesh. The 250-mesh size allows for slightly larger particles, absorbing more light energy while emitting a stronger glow. The 500-mesh size, on the other hand, allows for smaller particles, rapidly absorbing light and emitting a bright glow in a shorter period of time. Therefore, 250-mesh glow-in-the-dark powder is suitable for applications requiring a longer-lasting glow effect, while 500-mesh glow-in-the-dark powder is ideal for applications requiring a quick response and high brightness within a short period of time. This provides an optimal choice for different scenarios requiring both brightness and duration.

[0033] It is understood that the toner in the transparent film is a high-gloss black. This high-gloss black toner gives the transparent film a deep, bright black appearance during daylight hours or in bright conditions. This not only ensures the visual beauty of the engraved film during the day, but also avoids the dull or dull appearance of ordinary black films under bright light, thereby increasing the visual impact of the logo.

[0034] In this embodiment, the thickness of the luminous layer 2 is greater than that of the protective film layer 1, and the thickness of the luminous layer 2 is also greater than that of the translucent film. As the thickness of the luminous layer 2 increases, the content of the luminous powder also increases, allowing it to absorb more light energy. This means that the luminous layer 2 can store more light, further enhancing the brightness and duration of the lettering film's glow in the dark, making it more eye-catching and long-lasting at night or in low-light environments. Furthermore, although the luminous layer 2 is relatively thick, through the appropriate combination with the thinner protective film layer 1 and the translucent film layer, the entire lettering film can still maintain a flat and smooth appearance, facilitating lettering or cutting.

[0035] Furthermore, the combined thickness of the luminous layer 2 and the polyester hot-melt adhesive layer 4 accounts for at least three-fifths of the total thickness. By increasing the ratio of the luminous layer 2 to the hot-melt adhesive layer, the luminous powder content is relatively high, allowing for greater absorption of light sources. Furthermore, the increased thickness of the polyester hot-melt adhesive layer 4 provides stronger adhesion, ensuring stable adhesion of the engraving film to various surfaces.

[0036] In this embodiment, the lower end surface of the polyester hot-melt adhesive layer 4 is configured with an uneven, conical structure to increase its contact area. This conical structure creates an uneven surface on the lower end surface of the polyester hot-melt adhesive layer 4, significantly increasing the contact area between the adhesive layer and the adhesive surface. This larger contact area allows the hot-melt adhesive to better penetrate and adhere to surfaces of varying materials, thereby increasing adhesion strength and ensuring a more secure attachment of the engraving film.

[0037] It should be noted that a release paper is provided below the polyester hot melt adhesive layer 4 for easy peeling. The release paper allows the user to easily tear off the release paper when using the lettering film without affecting the adhesion of the polyester hot melt adhesive layer 4, simplifying the operation process, making it more convenient for the user to apply the film, and improving work efficiency.

[0038] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.
