Abstract: An object of the present invention is to provide an optical film which is excellent in the adhesiveness between a polymer support and a photo alignment film and in which a liquid crystal compound having reverse wavelength dispersibility is uniformly aligned. The optical film is obtained by laminating, in the following order: a polymer support containing an additive; a photo alignment film; and an optically anisotropic film, wherein the optically anisotropic film is formed of a polymerizable liquid crystal composition containing a polymerizable liquid crystal compound having reverse wavelength dispersibility, and an amount of a component derived from the additive of the polymer support, which is contained in a boundary region with the optically anisotropic film in the photo alignment film is 0.10 to 0.50 mass % with respect to a total mass of the photo alignment film.

Abstract: An object of the present invention is to provide an optical film having an optically anisotropic layer having excellent durability, and a polarizing plate and an image display device using the same. This optical film of the present invention is an optical film at least having an optically anisotropic layer, in which the optically anisotropic layer is a layer obtained by polymerizing a polymerizable liquid crystal composition containing a predetermined liquid crystal compound and a polymerization initiator, and the optically anisotropic layer has a density of 1.20 g/cm3 or more and a crosslinking point density of 0.0016 mol/cm3 or more.

Abstract: An ink pack is a laminate pack which at least one layer of an aluminum layer or an aluminum alloy layer and at least one layer of a plastic layer are laminated. An ultraviolet curable type inkjet ink composition which contains a compound having a nitroxyl radical, and has 1.2×1016 to 3.0×1019 of the spin number of the nitroxyl radical in one milliliter of the ink composition, is sealed in the ink pack.
