PROBLEM TO BE SOLVED: To maintain an antidazzle characteristic of a polarization film or a polarization complex and further to enable certainly discriminating color of an object like in a case of seeing with the naked eye without misconceiving colors by light transmitted therethrough. SOLUTION: This polarization film is colored and adjusted so that color coordinate values L, a, b in UCS color space are 22<=L<=70, -2.0<=a<=2.0, -2.0<=b<=2.0, spectral transmitivity at 410 to 750nm wavelength is within ±30% of the average value and transmitivity at 410 to 750nm wavelength is <=2% when two pieces of polarization films are superposed so as to orthogonally cross polarization axes (L is brightness divided into 0 to 100 and when denoted by three stimulus values X, Y, Z in CIE standard color specification system, L=100Y<1/2> , a=175(1.02X-Y)Y<-1/2> , b=70(Y-0.847Z)Y<-1/2> ). Otherwise, the polarization complex is constituted by incorporating a colorant into a constituting member thereof in which a polarization film is superposed on a translucent sheet or lens to integrate so as to attain transmitivity satisfying the condition described above. |
