    • An optical film is provided to obtain the optical film without using a phosgene and to perform the uniform polarized light conversion in wide wavelength region and to be useful for anti-reflection filters such as various liquid crystal displays, cathode-ray tubes, touch panels, and electroluminescence lamps, and liquid crystal projectors. An optical film forms a composition which contains a compound having the radical of the chemical formula (A) and has at least two group selected from the group consisting of an acryloyl group and methacryloyl group in a molecule, in a film form, and draws the composition. In the chemical formula (A), B1 and B2 independently show a hydroxyl group, C1-6 alkyl group, C1-6 alkoxy group or glycidoxy group; X shows divalent hydrocarbon group, sulfide group, sulfonyl group, and ether bonding or single bond, wherein the hydrocarbon group can contain -CO-O-, and a1 and 2 independently show an integer of 0 ~ 4.
    • 提供光学膜以获得不使用光气的光学膜并且在宽波长区域中进行均匀的偏振光转换,并且可用于各种液晶显示器,阴极射线管,触摸面板等防反射滤光片, 和电致发光灯和液晶投影仪。 光学膜形成包含具有化学式(A)的基团的化合物并且在分子中具有至少两个选自丙烯酰基和甲基丙烯酰基的基团的组合物,以薄膜形式,并且 组成。 在化学式(A)中,B1和B2独立地表示羟基,C1-6烷基,C1-6烷氧基或缩水甘油氧基; X表示二价烃基,硫醚基,磺酰基和醚键或单键,其中烃基可以含有-CO-O-,a1和2独立地表示0〜4的整数。
