The present invention relates to a self-healing polythiourethane polymerizable composition, a self-healing polythiourethane produced therefrom, and a self-healing optical material produced using the self-healing polythiourethane, and having excellent transparency and a high refractive index and Abbe number. When an optical material is produced using the self-healing polyurethane, surface scratches caused by the external environment can be easily restored by natural light such as sunlight. In addition, such advantages make it possible for the present invention to be widely used in optical lenses for precision equipment, optical lenses for image sensors for autonomous vehicles, optical lenses for radar sensors, camera lenses, and protective coatings for lenses, etc. La présente invention concerne une composition polymérisable de polythio-uréthane auto-réparante, un polythio-uréthane auto-réparant produit à partir de celle-ci et un matériau optique auto-réparant produit à l'aide du polythio-uréthane auto-réparant, qui présentent une excellente transparence, un indice de réfraction élevé et un nombre d'Abbe élevé. Lorsqu'un matériau optique est produit à l'aide du polyuréthane auto-réparant, les rayures de surface provoquées par l'environnement externe peuvent être facilement restaurées par une lumière naturelle telle que la lumière du soleil. De plus, de tels avantages permettent à la présente invention d'être largement utilisée dans des lentilles optiques destinées à un équipement de précision, des lentilles optiques pour des capteurs d'image destinés à des véhicules autonomes, des lentilles optiques pour des capteurs radar, des objectifs de caméra et des revêtements de protection pour des lentilles, etc. 본 발명은 자가치유성 폴리티오우레탄 중합성 조성물, 이로부터 제조된 자가치유성 폴리티오우레탄과, 상기 자가치유성 폴리티오우레탄을 이용하여 제조된, 투명성이 우수하고 높은 굴절률 및 아베 수를 갖는 자가치유성 광학소재에 대한 것이다. 상기 자가치유성 폴리티오우레탄으로 광학 소재를 제조할 경우, 외부 환경에 의한 표면의 스크래치를 햇빛 등의 자연광으로도 손쉽게 복구할 수 있다. 또한, 이러한 장점을 이용하여 정밀 장비의 광학렌즈, 자율주행차량용 이미지센서의 광학렌즈, 레이더 센서의 광학렌즈, 카메라렌즈, 및 렌즈의 보호 코팅 등의 용도로 폭넓게 사용될 수 있다.
