Abstract
One embodiment of the present invention relates to a hard coat film including a first layer in which a polymer of a polymerizable composition containing at least one polyfunctional polymerizable compound having two or more polymerizable groups in one molecule is detected as a main component and an organic solvent-soluble resin is not detected by composition analysis using a RAMAN spectroscopy; and a second layer adjacent to the first layer, in which an organic solvent-soluble resin and a polymer of a polymerizable composition containing at least one polyfunctional polymerizable compound having two or more polymerizable groups in one molecule are detected by the composition analysis, and a thickness is greater than 15 μm. Further, the present invention relates to a polarizing plate, an image display device, and a method for producing the hard coat film.
