Title:
SELF-HEALING POLYTHIOURETHANE POLYMERIZABLE COMPOSITION, SELF-HEALING POLYTHIOURETHANE PRODUCED THEREFROM, AND SELF-HEALING OPTICAL MATERIAL PRODUCED USING SAME
Document Type and Number:
WIPO Patent Application WO/2024/085454
Kind Code:
A1
Abstract:
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.
