<P>PROBLEM TO BE SOLVED: To solve the problem in the the environmental aspect of causing risk of using fire, noises, dust, a surplus soil or an odor. <P>SOLUTION: This road sign uses a photosensitive resin hardened by light irradiation A after masking by applying the photosensitive resin 8 to a road surface 10 (a drawing 3). Thus, since the road sign uses the photosensitive resin having a characteristic such as a type of becoming insoluble by the light irradiation or a type of being formed by hardening into a solid from liquid, consideration can be taken into safety using no fire, shortening of work requiring time, reduction in the number of persons engaging in work and an environment. <P>COPYRIGHT: (C)2004,JPO |
