PURPOSE: To prevent the release and separation of optical storage pigment and to preferably maintain a light emitting performance for a long period by mixing the pigment with the surface of a molding material for molding fiber- reinforced plastic. CONSTITUTION: A fiber-reinforced plastic 1 is obtained by forming a coating film 3 having predetermined color at the upper surface side of a reinforced resin layer 2 mixed with reinforcing fiber, forming a secondary resin layer 4 for a surface layer mixed with light storage pigment on the upper surface of the film 3, and forming a primary resin layer 5 for a surface layer at the upper surface side of the layer 4. The layer 2 is obtained by forming unsaturated polyester resin at the fiber. The layer 4 is obtained by mixing the unsaturated polyester resin and the pigment at the weight ratio of 10 to 1, and fixing it to the upper surface of the layer 2. The layer 5 is obtained by fixing epoxy resin having plenties of weather resistance and heat resistance to the upper surface of the layer 4. |
