Abstract

An optically softening resin composition contains a compound having a disulfide bond; and a radical scavenger. The compound having a disulfide bond may be a copolymer including a monomer unit having a disulfide bond and a functional group, and a monomer unit having a substituent reactive with the functional group. A curable resin composition contains a monomer having a disulfide bond and a functional group; a monomer having a substituent reactive with the functional group; and a radical scavenger.
