ABSTRACT:
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 aTand bT, respectively, and when in reflected light, displayed value b is designated as br, in the transmitted light, aTand bTare in the range of −2≦aT≦2, and −2≦bT≦1.3 and the difference between the displayed value b to the transmitted light and the reflected light is |(bT−br)|<10.
