The present invention relates to a thermoreversible brush polyacrylate network capable of self-healing a damaged portion of a coating surface generated by scratches or the like through a Diels-Alder / Inverse Diels Alder reaction, and its use, and more specifically, A polyacrylate copolymer resin containing a hydroxyl group; A self-healing polyacrylate composition capable of forming a thermoreversible network comprising a polyfunctional crosslinker containing a Diels-Alder adduct in its molecular structure and containing at least two isocyanate groups at the ends thereof, and a self- A clear coat having a scratch self-healing function, and a manufacturing method thereof. The thermoreversible self-healing polyacrylate composition according to the present invention has an advantage that it can be economically and effectively applied to automobile clearcoats and the like because it can form an acrylic coating layer having excellent mechanical properties while securing fast self-healing performance.
