PURPOSE:To obtain a hologram having excellent transparency and durability by subjecting the surface of the hologram to a film hardening treatment and adopting an epoxy adhesive agent as the adhesive agent. CONSTITUTION:The surface of the hologram is subjected to the film hardening treatment and the adhesive agent is the epoxy adhesive agent. After the surface of the hologram film is subjected to the film hardening treatment, a transparent protective body is stuck by the specific adhesive agent to the treated surface by which the deterioration in the properties of the hologram by the adhesive agent is prevented and the hologram having the excellent transparency and durability is obtd. The epoxy adhesive agent to be used is the compd. which is the resultant reaction product of epichlorohydrin and polyhydric phenol and has >=2 epoxy groups in the molecule as a chief material, compounding an acid anhydride and primary or secondary amine as a hardener and ternary amine, acid, phenol, alcohol, etc., as a catalyst therewith. The above-mentioned compd. compounded with polysulfide, polyamide, aniline resin, alkyl resin, etc. as a flexibility imparting agent is equally satisfactory.
