The reflective material is widely applied to the fields of life-saving clothes, traffic police clothes and the like, and the application field of reflective cloth is continuously expanded along with the maturity of the production process of the reflective material. With the application of reflective materials in consumer garments, people have increasingly high demands on the aesthetic appearance of reflective materials. At present, the color reflective materials in the market have low reflective brightness due to the color and color combination requirements, or have high reflective brightness but serious color distortion, so that the application of the color reflective materials in consumer clothes such as reflective clothes, various professional clothes, casual clothes, sportswear, fashionable dress, hats, gloves, backpacks and the like is limited.

CN200720306735 and CN200710160350 disclose a method for manufacturing a color reflective cloth, which adopts a PET-PE composite plant, then coats a color highly transparent color glue on the surface mainly made of glass, and compounds the glass with a base cloth after aluminizing, but the surface color of the method is not easy to control accurately.

CN101995596A discloses an exposed glass bead reflective film and a manufacturing method thereof, comprising a substrate, a reflective layer, a transparent color layer and a plurality of glass bead convex mirrors, wherein the reflective layer and the transparent color layer are sequentially arranged on the substrate, a plurality of glass beads are planted on the transparent color layer through the transparent bonding layer, each glass bead penetrates through the transparent bonding layer and is in point contact with the upper plane of the transparent color layer, and laser patterns can be pressed on the color layer according to requirements.

CN203025366U discloses a colored reflection of light goods, from bottom to top sets gradually substrate, colored resin layer, coating film layer, little coating layer and glass bead layer, and it guarantees the color effect of goods through increasing the coating film layer between colored resin layer and glass bead layer when improving reflection performance, nevertheless because the demonstration of its color is that the resin layer originally penetrated the performance of taking the color through adding the colour in the resin layer, the color still can receive the influence of cladding material, the product colour distortion.

CN200710160350 discloses a preparation process of a highlight color reflective fabric, which comprises coating a polyester film with a glue, drying, and then compounding with a polyethylene film to form a composite film, heating the composite film, planting glass beads on the surface of the composite film, adhering polyethylene to the glass beads, coating a layer of highly transparent color glue on the glass bead film, drying, then evaporating aluminum on the glass beads coated with the color glue, coating the aluminized glass bead film with a glue again, drying, compounding with a fabric, and finally peeling the aluminized film on the fabric layer to obtain the highlight color reflective fabric.

However, the product made by the method generates colors by the color layer, but the color distortion is more than that expected by the method, and the coefficient of retroreflection is low. Therefore, the black reflecting material with high brightness and the preparation method thereof are provided.
