開発されている。[Prior art and problems to be solved by the invention] In recent years,
Various types of fluorescent sheets are produced, and most of them are processed with adhesives and the like to suit the purpose, and are widely used for signboards, stickers, etc. due to the high visibility of fluorescent colors and ease of processing. In addition, fluorescent dyes, which are the basis of the coloring properties of fluorescent sheets, have been developed, and high-performance fluorescent pigments have been developed by dyeing and pulverizing fluorescent dyes.

を薄くしていた。However, most of the current fluorescent sheets use a solvent-based coating agent, which is a mixture of a fluorescent pigment, an ultraviolet absorber, etc., in a solvent-based varnish, for the fluorescent colored layer and the ultraviolet absorbing layer.
The strength of the sheet mainly depends on the white or co-colored vinyl chloride film used for the reflective layer. As a result, in the case of a white or co-colored vinyl chloride film, it is necessary to have both the hiding rate required as a reflective layer and a large contribution to sheet strength, so in practical terms, in the calendar method, 70 μm, Even in the sol coating method, a minimum film thickness of 50 μm was required. In the case of fluorescent sheets, the overall thickness varies depending on the application, but generally the thinner the sheet, the better, as long as there is no problem with weather resistance and the fluorescent color can be maintained. If a certain level of thickness is required, it can be easily increased by laminating it with other films, but if thinness is required, the fluorescent colored layer can be made thinner at the cost of sacrificing weather resistance, etc. was.

とは可能であるが、発色性、耐候性等が低下し易い。[0006] The color development and weather resistance of the fluorescent colored layer improves as the thickness of the paint containing a large amount of fluorescent pigments with good weather resistance is applied, but since the fluorescent pigment content is large, the contribution to sheet strength is small. . In addition, when transparent vinyl chloride resin or the like is dyed with a fluorescent dye or mixed with fluorescent pigments to form a fluorescent colored layer and made into a film using a thermal calendaring method or a sol coating method, the sheet strength depends on the fluorescent colored layer. Although it is possible to do so, color development, weather resistance, etc. tend to deteriorate.

能等の付加も容易になった。Therefore, in the present invention, the sheet strength mainly depends on the ultraviolet absorbing layer, and the reflective layer, which conventionally had sheet strength etc., is increased in content of a coloring agent such as titanium white to improve the hiding rate. By using a coating layer of white paint with improved properties, it was possible to reduce the film thickness. Furthermore, it has become possible to easily add adhesive functions, adhesion functions, co-color functions, etc. while maintaining the reflective function. In addition, in terms of process, conventionally a fluorescent colored layer was coated on top of the reflective layer and then an ultraviolet absorbing layer was coated, but in the present invention, basically a fluorescent colored layer is coated on top of the ultraviolet absorbing layer. Since the layers are provided by coating and finally the reflective layer is provided by coating, the lot quantity of the reflective layer can be reduced, and it is also easy to add co-color functions, adhesive functions, adhesive functions, etc.

In addition, if the ultraviolet absorbing layer is made of acrylic film or vinyl chloride film, thermal lamination is possible. One way to take advantage of the workability of thermal lamination is to provide a fluorescent colored layer in advance.
