PROBLEM TO BE SOLVED: To provide a radiation curable liquid resin composition for an optical solid molding having a good preservation stability as a liquid state before curing, also capable of obtaining an optical molded material having an excellent rigidity directly after its molding by curing, and also excellent in transparency over a long period. SOLUTION: This liquid state resin composition contains a compound having a structure expressed by formula (1), a compound having a phenolic hydroxy group and/or phosphorous acid ester group, a cationically polymerizable compound having≥2 oxetane structures, another cationically polymerizable compound other than the above compound, a radical polymerization initiator, a radically polymerizable compound and water, and also has a congeneric but heterogenous structure.
