As shown in FIG. 1, a caution label S for a hydraulic shovel according to the present embodiment is provided on a base material 1, an adhesive layer 2 provided on the back surface of the base material 1, and a front surface of the base material 1. And a transparent protective layer 3. As described above, the caution label S for a hydraulic shovel is composed of the three layers of the protective layer 3, the base material 1, and the adhesive layer 2, and is formed such that its thickness is about 100 μm.

The adhesive layer 2 is provided for adhering to the counterweight 11 of the hydraulic shovel 10, and the release paper is detachably adhered until it is adhered. Here, various adhesives can be used as the adhesive constituting the adhesive layer 2, and for example, an acrylic adhesive can be used.

The substrate 1 is made of a flexible sheet material and is made of a synthetic resin sheet such as a vinyl chloride resin.

A display section 4 is provided on the front side of the substrate 1. The display section 4 is provided with a luminous paint 4 a applied to the surface of the substrate 1 and a back side of the protective layer 3 ( White print pattern P of desired characters, figures, etc. formed on base material 1)
It consists of: Here, the luminous paint 4a is applied to the entire surface of the substrate 1.

As the luminous paint 4a of the display unit 4, various kinds of luminous paints can be adopted. However, those having luminous properties which emit light spontaneously for 2 hours or more after the irradiation light has disappeared are preferable. More preferably, it has a light storage property of 8 hours or more.

As a material of the luminous paint 4a, for example, M _{1 -x} Al ₂ O _{4 -x} (M is at least one element of calcium, strontium and barium, and X is -0.1.
(33 or more and 0.6 or less) can be used. More specifically, it is possible to use a paint containing a strontium aluminate compound (for example, trade name “Ecoluna” manufactured by Nemoto Special Chemical Co., Ltd.).
