PURPOSE: A coating composition is provided to secure the blocking resistance, to improve the adhesive property with a printing ink, a laminate, and other coating agents, and to produce a polyamide film with the improved water resistance. CONSTITUTION: A coating composition with the strong adhesive property contains 100 parts of aqueous hybrid emulsion by weight, and 2~25 parts of melamine-based hardener by weight. The aqueous hybrid emulsion is formed by mixing an aqueous polyurethane group emulsion and an aqueous acrylic emulsion. 100 parts of aqueous hybrid emulsion by weight includes 3~97 parts of aqueous polyurethane group emulsion, and 97~3 parts of aqueous acrylic emulsion by weight. |
