The present invention relates to an ultraviolet curable coating composition for PVC sheet, and more particularly, to an aliphatic isocyanate having an allophanate structure and an aliphatic allophanate urethane acrylate oligomer produced by reacting a monofunctional or polyfunctional hydroxy acrylate. A UV curable coating composition comprising a polyfunctional acrylate modified monomer, a monofunctional acrylate monomer, and a photopolymerization initiator, wherein the composition has excellent scratch resistance, flexibility, and chemical resistance when applied to a polyvinyl chloride (PVC) sheet.
