PROBLEM TO BE SOLVED: To provide a water-borne clear coating composition in which problems such as low boiling point solvent, volatile organic compound, aggregation of liquid by chitosan, water resistance, formation of coating film having low transparency, weather resistance, stable supply of coating liquid are solved. SOLUTION: The water-based clear coating composition comprises chitosan-containing emulsion obtained by previously preparing an emulsion containing chitosan or its derivative and a radical-polymerizable monomer and an emulsion containing a polymerization initiator and adding the former emulsion to the latter emulsion and polymerizing the monomer.
