ULTRAVIOLET ABSORBER, OPTICAL FILM CONTAINING THE SAME, PROCESS FOR PRODUCING OPTICAL FILM, AND POLARIZER AND LIQUID-CRYSTAL DISPLAY EACH EMPLOYING THE SAME

摘要

An ultraviolet absorber which has excellent spectral absorption performance, does not color, gives excellent transparency, and is reduced in bleeding; an optical film containing the absorber and reduced in retardation fluctuation; and a polarizer and a liquid-crystal display each employing the film which are excellent in long-term light resistance and durability and retain a high contrast. The optical film is characterized by containing an ultraviolet absorber represented by the following general formula (1).[Chemical formula 1]General formula (1).
