もよい。Silicones, stearates, soaps, and other materials commonly used in rubber plastics are used. These fluorescent pigments and mold release agents are dispersed and mixed in an appropriate solvent, and then applied to the molding surface 01 of the mold cavity O using a spray brush or the like.
After coating and drying, fill the mold cavity O with the usual method.
A foamable liquid polyurethane is introduced into the shoe, and this is foamed and cross-linked to form the foamed polyurethane sole 1. The sole is a unit sole that is attached to the heel of the shoe with an adhesive or the like. Alternatively, it may be a direct sole that is integrally bonded to the heel of the shoe at the same time as the sole is molded.

るものと考えられる。A mold release agent containing no fluorescent pigment was applied to the thus obtained shoe sole and molding surface, and a foamable liquid polyurethane was introduced into the dried mold cavity to form the sole of the shoe shown in the example. A comparison shoe sole obtained by foam crosslinking in the same manner as above was irradiated with radiant light from a black light (UV 352 nanometers) for 240 hours, and the change in color tone over time was compared a.
As a result, the sole of the comparative example had poor visibility and turned yellowish brown over time, but the sole of the example had good visibility and no discoloration was observed. The reason for this is that in this example, the ultraviolet rays contained in the radiation light are reflected as optical energy by the fluorescent pigment contained in the fluorescent pigment layer 2 formed on the surface of the polyurethane foam sole 1, and the polyurethane foam sole 1 is It is thought that it protects from ultraviolet rays and improves the clarity of the pigment.

離形性も良好である。In addition, in the present invention, since the fluorescent pigment is added to the mold release agent, there is no need for a separate step of applying the mold release agent to the molding surface o1 of the mold cavity, and the molding of the sole is efficient. The releasability of the molded shoe sole from the mold cavity is also good.
