摘要:
A novel optical film is provided that exhibits a wavelength dispersion (a reverse wavelength dispersion) such that the birefringence of the film decreases as the wavelength becomes shorter, at least in the visible light range. The optical film includes a layer formed of a resin (A) having a heteroaromatic group or a molecular structure represented by the following formula (1), (2) or (3):
where in the formula (1), n is a natural number in the range of 1 to 4, and R 1 and R 2 each independently represent a hydrogen atom or a methyl group. The optical film exhibits a wavelength dispersion such that the birefringence of the film decreases as the wavelength becomes shorter, at least in the visible light range.
摘要:
A borate for a near-infrared ray absorption material, having an anion represented by the formula (1): [BR1mR24-m]- (wherein R1 represents an aryl group having an electron withdrawing group; R2 represents an organic group, a halogen group or a hydroxyl group; and m is an integer in the range of 1 to 4) is provided. The borate of the present invention enables to improve durability, in particular, heat resistance and moisture resistance of a near-infrared ray absorbing dye.
