PROBLEM TO BE SOLVED: To provide: a resin material for optical recording, which has excellent transparency, a strong matrix, and highly reliable resistance to storage environment even at a high temperature and a high humidity; a method for producing the resin material for optical recording, in which it is easy to control the production conditions of the resin material, thereby being excellent in economical advantage; and an optical recording medium using the resin material for optical recording. SOLUTION: The resin material for optical recording is composed of: a matrix resin in which an epoxy resin cured by an acid anhydride forms a network structure; a photopolymerizable monomer dispersed in gaps of the network structure of the matrix resin; and a photoinitiator. The resin material for optical recording with which a diffraction efficiency of≥50% can be obtained by hologram recording using a light having an intensity of≤50 J/cm<SP>2</SP>is used in a recording layer 5 of the optical recording medium 1A.
