A composition in which refractive index control is possible and which, when applied to a substrate such as a resin and cured, gives a film excellent in marring resistance and adhesion (especially to resins having thiourethane bonds or epithiosulfide bonds). The composition is characterized by containing: a thio(meth)acrylate compound and ultrafine inorganic particles. (1) (In the formula, connecting group R represents an aliphatic residue, aromatic residue, alicyclic residue, or heterocyclic residue or an aliphatic residue having in the chain an oxygen atom, sulfur atom, aromatic ring, aliphatic ring, or heterocycle; Rm's each independently represents hydrogen or methyl; and n is an integer of 1 to 4.) |
