Disclosed is a photosensitive composition for volume hologram recording which is used for recording an interference fringe produced by a laser beam or a light having excellent coherence, as fringes having different refractive index. The composition comprising:
(a) a cationic polymerizable compound which is liquid at ambient temperature;
(b) a radical polymerizable compound;
(c) a radical photopolymerization initiator composition sensitized by a laser beam or a light having excellent coherence which has a specific wavelength to polymerize the ingredient (b); and
(d) a cationic photopolymerization initiator composition which shows low photosensitivity to the light having a specific wavelength and is sensitized by a light having the other wavelength to polymerize the ingredient (a), wherein an average refractive index of the ingredient (a) is smaller than that of the ingredient (b). A process for producing the photosensitive composition is also disclosed.
