It provides a monomer mixture for rapidly curing even in the presence of oxygen to form a cured product having high hardness and excellent adhesion to metal or glass. The monomer mixture of the present invention is a monomer mixture containing two or more cationic polymerizable monomers, as the cationic polymerizable monomer, at least one cationic polymerizable group selected from vinyl ether group, epoxy group and oxetanyl group in one molecule, and , A compound having at least one hydroxyl group is contained in an amount of 10% by weight or more of the total amount of the monomer mixture, and in the following formula (b) (in the formula, R is an s-valent linear or branched saturated aliphatic hydrocarbon group, or two or more linear Alternatively, a branched saturated aliphatic hydrocarbon group represents an s-valent group bonded via an ether bond, and s represents an integer of 2 or more) and contains 5% by weight or more of the total amount of the monomer mixture. |
