摘要

A photopolymerizable composition, which contains: a monofunctional monomer having a viscosity of 5 mPa・s or less at 25℃; one or more polyfunctional monomers including glycerol dimethacrylate; and a polymer free from a hydrophilic functional group, wherein a mass ratio (A/B) of an amount (A) of the polymer free from a hydrophilic functional group to an amount (B) of the polyfunctional monomer is greater than 0.80 but 3 or less.
