PURPOSE:To obtain the titled composition which can easily give a cured prouduct free of surface tackiness within a short time, by mixing a specified radical-polymerizable resin composition with a eutectic mixture containing a brominated diphenyl ethers and, optionally, diphenyl ether. CONSTITUTION:A radical-polymerizable resin composition (A) is obtained by mixing a prepolymer (a) having at least two (meth)acrylonitrile groups in the molecule [e.g., a prepolymer formed by bonding at least two (meth)acrylonitrile groups to a urethane oligomer] with 10-50wt%, based on component A, monomer (b) having at least one ethylenically double bond in the molecule (e.g., 1,6-hexanediol diacrylate) and 0.1-10wt%, based on the mixture of components (a) and (b), photosensitizer (e.g., benzil dimethyl ketal). 100pts.wt. component A is mixed with 3-50pts.wt. eutectic mixture (B) of brominated diphenyl ethers and, optionally, diphenyl ether and, optionally, a filler, a pigment, an antifoamer, a heat polymerization initiator, etc.
