Abstract:
1. An active energy ray-curable resin composition comprising a multifunctional monomer (A); and a mono(meth)acrylate (B) having a polyethylene glycol structure having a number of repeating ethylene glycol units of 9 or more, wherein the content of the multifunctional monomer (A) is 70 to 95 parts by mass, and the content of the mono(meth)acrylate (B) is 5 to 30 parts by mass, here the total content of all monomers contained in the resin composition is 100 parts by mass, wherein the multifunctional monomer (A) is at least one selected from the group consisting of urethane (meth)acrylate, epoxy (meth)acrylate, polyester (meth)acrylate, ethoxylated trimethylolpropane triacrylate and ethoxylated pentaerythritol tetraacrylate, and contains three or more radical polymerizable functional groups, and has a value obtained by dividing molecular weight of the multifunctional monomer (A) by the number of radical polymerizable functional groups (molecular weight per functional group) of 110 to 200.
