Hard coat film, polarizing plate comprising same, image display device and method for producing hard coat film

One embodiment of the present invention relates to a hard coat film which comprises: a first layer from which a polymer of a polymerizable composition containing at least one polyfunctional polymerizable compound having two or more polymerizable groups in each molecule is detected as a main component but an organic solvent-soluble resin is not detected in a composition analysis thereof by Raman spectroscopy; and a second layer which is adjacent to the first layer and has a thickness of more than 15 um, and from 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 each molecule are detected in the above-mentioned composition analysis. The present invention also relates to a polarizing plate, an image display device and a method for producing a hard coat film.
