Self-healing transparent coating composition using sunlight and application thereof

Abstract

Provided are a clearcoat having a self-healing thermoreversible network by topically generating heat in a scratched site using NIR laser, using a reversible bond occurring by heat by sunlight or heat at high temperature occurring in the photothermal dye by ultraviolet rays, by including: a multi-functional crosslinking agent including a hindered urea structure and an alkylene oxide repeating unit and a photothermal dye compound generating heat by mainly absorbing light in the NIR region, as a coating composition capable of self-healing scratches occurring on the surface, and a method for preparing the same.

Dependencies are inferred from the claim text.
