[0002] The glass bead light reflection film is made of glass beads.

[0003] The light reflection principle of the light reflection film is mainly based on the inverse reflection principle, in order to increase the color of the reflection of the light reflection film, the prior art usually adds a color layer before the light enters the glass bead, and the light of a specific color is reflected by the glass bead after passing through the color layer.

[0004] But this also weakens the light intensity of the light reflected by the light reflection film, so the brightness of the reflected light is reduced from the visual point of view, and the light reflection rate of the light reflection film is reduced. INVENTION CONTENTS

[0007] The utility model further sets up: tonal layer is connected with metal layer, and the demarcation line is parallel to the circular shape of membrane body thickness direction.

[0008] The utility model further sets up: the tonal layer is gradually increased from the surface of the glass bead contact to the position away from the glass bead cross section, and a plurality of tonal layers are connected.

[0009] The utility model further sets up: the light transmission layer is made of resin material, and the gap between tonal layer and metal layer is filled with resin material.

[0010] The utility model further sets up: the light transmission layer is fixedly provided with the protective film on the side away from tonal layer.

[0011] The utility model further sets up: the tonal layer is sequentially fixedly provided with pressure sensitive adhesive layer and release layer on the side away from the light transmission layer.

[0012] Summarized above, the utility model has following beneficial effect: compared with traditional colored glass bead light reflection film, by setting tonal layer in the position of part light path through the glass bead can be reflected or diffracted, another part light path still can carry out inverse reflection, thereby effectively improve the overall brightness of colored light reflection film.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] A colorful reflective film, such as Figure 1 As shown, the membrane includes a light-transmitting layer 2. Several glass microspheres 3 are fixedly embedded on one side of the light-transmitting layer 2. A metal layer 4 is coated around one end of each glass microsphere 3, and a color-matching layer 5 is coated at the position surrounded by the metal layer 4. In addition, several color-matching layers 5 are connected at positions away from the glass microspheres 3. A protective film 1 is fixedly disposed on the side of the light-transmitting layer 2 away from the color-matching layer 5. A pressure-sensitive adhesive layer 6 and a release layer 7 are sequentially fixedly disposed on the side of the color-matching layer 5 away from the light-transmitting layer 2.

[0021] like Figures 2 to 5As shown, specifically, the PET substrate in honeycomb form is coated with a resin material to form the light transmission layer 2, and then a plurality of glass beads 3 are implanted on the light transmission layer 2 by electrostatic implantation to form a single layer structure of the glass beads 3, and then the surfaces of the glass beads 3 that need to be reflective are coated with a focusing layer;

[0022] The position of the subsequent glass beads 3 for coating the color adjusting layer 5 is covered by a special template, and then vacuum evaporation is performed to form a metal layer 4 on the surface of the glass beads 3, and then the position of the template is maintained, and a layer of resin material containing pigments is coated on the position reserved by the template, and then the color adjusting layer 5 is formed after waiting for cooling, and finally the release layer 7 coated with a pressure-sensitive adhesive layer and the protective film 1 are compounded, and the production and manufacturing of the embodiment are completed;

[0023] In the production of the method, the template is in the shape of a circular truncated cone, which facilitates the detachment of the template in subsequent steps, and because a colorless resin material is coated once after the formation of the metal layer 4, the template does not easily affect the coating of the metal layer 4 when it is separated, and the cross section of the color adjusting layer 5 gradually increases from the surface in contact with the glass beads 3 to the position away from the glass beads 3, which effectively connects the color adjusting layer 5 and the metal layer 4, and the boundary line is in the shape of a circle parallel to the thickness direction of the film, reducing the position where the glass beads 3 at one end are not covered by the metal layer 4 and the color adjusting layer 5, and maintaining the degree of light reflection.

[0024] Beneficial effects: Compared with traditional colored glass beads 3 reflective film, by setting the color adjusting layer 5 at the position where part of the light path can be reflected or diffracted through the glass beads 3, another part of the light path can still be retroreflected, thereby effectively improving the overall brightness of the colored reflective film.
