PROBLEM TO BE SOLVED: To provide a composition for a hologram recording material capable of forming a hardened film excellent in heat resistance, scuffing and wear resistances and having good adhesion to a metal vapor-deposited film and another resin layer, and capable of contributing to an improvement in hologram productivity, and to provide a hologram recording material stably producible with high productivity, a relief hologram and a method for producing a hologram. SOLUTION: The composition for a hologram recording material comprises (A-1) 20-90 wt.% of a resin having a (meth)acryloyl group and (B) 10-80 wt.% of colloidal silica having a primary particle diameter of 1-200 nm. Such a composition for a hologram recording material is also provided which comprises (A-2) a resin having an alkoxysilyl group and a (meth)acryloyl group and an organic-inorganic complex obtained by hydrolyzing and condensing colloidal silica and/or a silicate.
