Disclosed is a self-healing acrylic copolymer represented by Formula 1:  The acrylic copolymer can self-heal structural damages such as scratches with the aid of heat and water and possesses excellent physical properties at room temperature. Also disclosed is a crosslinked copolymer prepared from the acrylic copolymer.

Self-healing acrylic copolymer, crosslinked copolymer prepared from the acrylic copolymer and method for low-temperature self-healing of the crosslinked copolymer

A method of treating a surface of a substrate using modified urushiol derived fromis provided. More particularly, the reactivity of a hydroxyl group of urushiol extracted from freshis removed before the lacquer is used as a UV coating agent for a substrate such as a steel sheet. Therefore, the substrate may have high antibacterial activity, and excellent appearance and functionalities such as far-infrared radiation, blocking of electromagnetic waves, enhanced corrosion resistance, high crosslinking speed when a low content of a photoinitiator is used, excellent surface gloss and high scratch resistance.
