PROBLEM TO BE SOLVED: To provide a road marking sheet in which heat deformation is not generated, in which a desired hardness can be obtained, in which cracking is not generated at the time of moulding, in which weather resistance and abrasion resistance of the sheet after construction are excellent, in which less deformation is generated by pressure by traffic vehicles, in which visibility at night is favorable, and in which, especially, less deterioration of visibility at night by aging occurs. SOLUTION: A road marking sheet comprises thermosetting resin composition comprising main components of acrylic polyol which is solid or solid solution at a room temperature composed by radical polymerization of vinyl monomer including (meth)acrylic monomer including at least one sort of a hydroxyl group, an amide group, and a carboxyl group, block isocyanate, and light accumulative material. A thickness of the sheet is 0.5mm or more and 35mm or less, and a weight-average molecular weight of acrylic polyol is 0.11 million or more and 1.5 million or less. |
