By providing a composition in which refractive index can be controlled, and scratch resistivity and adhesion (especially adhesion to a resin having a thiourethane bond or epithiosulfide bond) are excellent when the composition is coated on a base material such as a resin and then cured, the composition comprises (a) a thio(meth)acrylate compound represented by the general formula (1) and (b) ultrafine inorganic particles:
wherein a linking(or connecting) group R represents an aliphatic residue, an aromatic residue, an alicyclic residue or a heterocyclic residue or an aliphatic residue having an oxygen atom, a sulfur atom, an aromatic ring, an aliphatic ring, or a heterocycle in the chain; R
m
represents each independently a hydrogen atom or a methyl group; and n is an integer of 1 to 4.
通过提供一种组合物,该组合物在涂覆到树脂等基材上并固化后,折射率可控,且抗划伤性和粘附性(尤其是与具有硫代氨基甲酸酯键或表硫代硫酰基键的树脂的粘附性)优异,该组合物包括(a)通式(1)表示的硫代(甲基)丙烯酸酯化合物和(b)超细无机颗粒:
其中连接(或连接)基团 R 代表脂肪族残基、芳香族残基、脂环族残基或杂环族残基,或在链中具有氧原子、硫原子、芳香环、脂环或杂环的脂肪族残基; R
m
分别独立地代表一个氢原子或一个甲基;以及 n 是 1 至 4 的整数。
