PURPOSE: A coating composition is provided to ensure excellent adhesive property and good blocking resistance, and to avoid the separation between ultraviolet curable ink and a substrate due to an excellent adhesive property. CONSTITUTION: A coating composition includes 100 parts by weight of an aqueous hybrid type emulsion and 2~25 parts by weight of a melamine-based hardener. In the aqueous hybrid type emulsion, an aqueous polyurethane-based emulsion and an aqueous acrylic emulsion are mixed. Based on 100 parts by weight of the aqueous hybrid type emulsion, the aqueous acrylic emulsion solid portion is 97 parts by weight when an aqueous polyurethane group emulsion solid portion is 3 parts by weight, and the aqueous acrylic emulsion solid portion is3 parts by weight when an aqueous polyurethane group emulsion solid portion is 97 parts by weight.
