に関するものである。
エピスルフィド化合物を含有する組成物を重合硬化して得たエピスルフィド系樹脂は、非常に高い屈折率とアッベ数を同時に有する優れたものであるものの、脆い上に耐衝撃性が非常に低いと言った欠点をも有しているものである。これに対して、ポリチオール化合物、ポリイソシアナート化合物を含有する組成物を重合硬化して得られるポリチオウレタン樹脂は、非常に高い屈折率とやや低めのアッベ数を有するものの、非常に優れた強度を有するものである。現在盛んに行われている検討では、それぞれの樹脂の優れた点を生かすべく、エピスルフィド系樹脂とポリチオウレタン樹脂を一緒に重合させることで、得られる樹脂の屈折率やアッベ数は高いままで、脆さや耐衝撃性の低さを改良する方法が提案されている。しかしながら、提案されている内容では光学材料、特に眼鏡レンズを用途とする分野では、改良のレベルが低く、更なる改良が必要である。
