Furthermore, not clothes but bags, shoes, hats, etc. It may be pasted on the surface of the product, and by configuring in this way, the fabric of the product itself can be utilized and fashionability can be improved by matching the color, pattern, etc. of the product.

  In the above embodiments, the retroreflective sheet main body 1 has a structure in which a hot melt layer 1d is provided on the back surface and the hot melt layer 1d is formed so as to be hot-pressed on clothes or the like. However, without providing such a hot melt layer, as shown in FIG. 7 and FIG. 8, an infinite number of fine spherical glass beads are uniformly distributed on the surface layer through the reflective layer 1b made of a thin metal deposition layer such as aluminum. A retroreflective sheet main body 1 'having a structure in which a lining fabric 5 made of a woven fabric or a net is integrally layered on the back surface of a bonding layer 1a made of a transparent soft resin such as polyester and the like is formed, and this retroreflection is formed. It may be a retroreflective sheet formed by punching a large number of through holes 2 in the sheet main body 1 ′. In this case, when the back fabric 5 is made of a fabric having good air permeability, the back fabric 5 can reach the back surface of the bonding layer 1a from the surface of the retroreflective sheet main body 1 'without providing the through holes 2. Alternatively, the through hole 2 may be formed.

  The usage of the retroreflective sheet configured in this way is the same as in the above embodiment, but when it is appropriately cut into a shape and attached to clothes or the like, it is performed by sewing without sticking. Further, the retroreflective reflection is formed by integrally providing a back fabric 5 made of a woven fabric or a knitted fabric in which the through-holes 2 are not drilled on the back surface of the retroreflective sheet main body 1 ′ having the numerous through-holes 2. As an example of the use of a sheet, a pocket, a collar, a sleeve, etc. of a garment may be produced by using this retroreflective sheet. Can give a special accent and improve fashionability.

  In addition, in the said Example, although the circular thing is shown as a shape of the through-hole 2 drilled in the retroreflection sheet main bodies 1 and 1 ', it is not limited to such a shape. For example, as shown in FIGS. 9 (a) to 9 (c), a star-shaped through-hole or a shape designed by combining irregular-shaped through-holes 2 and 2 such as a triangle or an ellipse may be used. Furthermore, a perforated form in which letters and designs are drawn by a large number of through holes may be used. In addition, examples of the use of the retroreflective sheet pieces A and A ′ are not limited to the clothes B, but may be a bag, shoes, a hat, or the like. Also good.
