RETROREFLECTION SHEET HAVING GOOD VISIBILITY

摘要

PURPOSE:To provide the retroreflection sheet which is sufficiently visible even in the daytime by providing at least one surface of a retroreflective element with a transparent fluorescent colored layer thereon. CONSTITUTION:The transparent fluorescent colored layer 12 is formed by coating a polyethylene terephthalate film 11 with a transparent fluorescent colored coating material. A transparent colored coating material is applied on the transparent fluorescent colored layer 12 to form a transparent colored layer 13A and a transparent colored coating material is applied on this transparent colored layer 13A to form a bead stuck layer 13B. Beads 14A are stuck to the bead stuck layer 13B. Focus layers 14B and 14C consisting of art acrylic resin and others are then successively formed thereon and aluminum is deposited by evaporation on the focus layer 14C, by which a light reflection film 14D is formed. The retroreflective element 14 is constituted of the beads 14A, the focus layers 14B and 14C and the light reflection film 14D. A laminated sheet having the film 11, the transparent fluorescent colored layer 12, the transparent colored layer 13 consisting of the transparent colored layer 13A and the bead stuck layer 12B and the retroreflective element 14 is laminated on a base material sheet 15.
