PURPOSE:To obtain a retroreflective sheet-like material having bright color and excellent visibility by making a reflecting layer of a coloring agent and reflective material resin and forming a bead layer of a resin contg. a light accumulative material and transparent spherical body. CONSTITUTION:A titled sheet-like material is constituted basically of a reflecting layer 3 which is a resin film contg. a fluorescent pigment 11 and mica titanium 10 and a bead layer 6 which is a resin film contg. beads 1 and a light accumulative pigment 2 on a sheet-like material 5 such as canvas, film or metallic sheet to be used as a base body. A white layer 4 which is a resin film contg. titanium dioxide 12 to increase a bright color effect exists more preferably in said material. Good retroreflective performance is obtd. with 1.5-1.92 refractive index of the beads 1. The base body 5 is formed thereon with the white layer 4 consisting of titanium dioxide 12, the reflecting layer 3 having the fluorescent pigment 11 and mica titanium 10, the bead layer 6 contg. the light accumulative pigment 2 and the beads 1. |
