<p>An optically semi-transmission reflection material comprises a resinous film comprising a thermoplastic resin, wherein the sum of total light ray transmittance, T%, and total light ray reflectance, R%, i.e., T + R, is 80 to 100; an absolute value of their difference is (T - R) < 50%; when displayed value a and displayed value b in transmitted light are designated as aT and bT, respectively, and when in reflected light, displayed value b is designated as br, in the transmitted light, aT and bT are in the range of aT≤2, and bT≤1.3 and the difference between the displayed value b of the transmitted light and the reflected light is (bT - br) < 10. <IMAGE></p> |
