A composition for holographic recording medium, which can be coated in a uniform thickness and enables to simply produce a high definition holographic recording medium is provided. And a holographic medium having a low error rate, high storage capacity, high-performance, high-density, which is produced using the composition for the holographic recording medium, is also provided. The composition comprises a (meth)acrylic acid ester group-containing polymerizable substance, an alicyclic epoxy group-containing cationical polymerizable substance of which is ring-opening polymerized by heat, and a hydroxyl group-containing substance which is reactive with the alicyclic epoxy group-containing cationical polymerizable substance. The holographic recording medium is produced by forming a holographic recording layer on a substrate by applying the composition on the base material and polymerizing the alicyclic epoxy group-containing cationical polymerizable substance and the hydroxyl group-containing substance.
