The present invention relates to a cationic photosensitivity having excellent photocuring properties, moisture permeability resistance, and corrosion resistance, which has never been achieved while maintaining the performance of conventional cationic systems with good adhesiveness and low curing shrinkage. Provided are a composition and a cured product thereof, and a method for producing an optical disk and a flat panel display using the composition. SOLUTION: (a) 10-95% by mass of a cationically polymerizable compound, (b) 0.1-90% by mass of an aromatic compound having at least two aliphatic hydroxyl groups, (c) initiation of energy ray sensitive cationic polymerization An optical disk and a flat panel display are formed using the photosensitive composition characterized by containing 0.1-20 mass% of agents, and its hardened | cured material. [Selection figure] None |
