Abstract
The present invention relates to a novel polyrotaxane compound having a specific chemical structure, a photocurable coating composition that may provide a coating material having excellent mechanical properties such as scratch resistance, chemical resistance, abrasion resistance, and the like, and excellent self-healing capability, and a coating film obtained from the photocurable coating composition.
Claims19
A polyrotaxane compound comprising:
- a macrocycle to which a lactone-based compound is bonded;
- a linear molecule penetrating the macrocycle;
- and blocking groups arranged at both ends of the linear molecule and preventing the macrocycle from escaping,
- wherein a final substitution rate at the end of the lactone-based compound bonded to the macrocycle of the polyrotaxane compound is 40 mol % to 70 mol %.
