Abstract

A curable resin composition includes a multifunctional radical polymerizable compound (A), a monofunctional radical polymerizable compound (B), a rubber particle (C), and a radical polymerization initiator (D). The compound (A) includes a multifunctional urethane (meth)acrylate oligomer (a1) in a certain amount based on the total amount of the compounds (A) and (B). The compound (A) and/or (B) contains at least one radical polymerizable compound satisfying expressions (1) to (3) in a certain amount based on the total amount of the compounds (A) and (B). The compound satisfies the expressions (1) to (3) and is a compound other than the oligomer (a1): log(S)≤0.4 (1), 3.0≤δP value≤6.0 (2), molecular weight≤500 (3), log(S) is a common logarithm of solubility in water at 25° C., and δP value is a value of dipole interaction energy in Hansen solubility parameter.
