することを目的とする。[Problems to be Solved by the Invention] However, applying a primer when applying heat-melting road marking materials requires not only the application time but also the complete volatilization of the solvent. The drawback is that it must be applied after drying (residual solvent may cause softening, staining, and peeling of the paint film over time), and the drying time is 5 to 20 minutes. . In order to reduce traffic stagnation even a little, it is desirable to shorten the time by even one minute. Therefore, the purpose of the present invention is to solve the above problems and provide a heat-melting road marking material that does not require a primer. do.

F, or AlCl, obtained by catalytic stereoregular polymerization, cationic polymerization, molecular weight 200-4000, especially 4
Those with a molecular weight of 30 to 1,350 are preferably used. Those with a molecular weight of less than 200 have poor adhesion to the road surface, and those with a molecular weight of more than 4,000 have a high melt viscosity for road marking materials, resulting in poor workability and fluidity, and poor durability. The staining property is also reduced, which is undesirable.The molecular weight in the present invention is the viscosity average molecular weight of F.
It was measured according to the CC method.
