An object of the present invention is to provide an antifouling coating composition capable of obtaining an antifouling coating film excellent in discoloration resistance and capable of maintaining high antifouling properties for a long period of time. Further, the present invention provides an antifouling coating film formed from the above-mentioned antifouling coating composition, a substrate with an antifouling coating film, and a method for producing the same. The antifouling coating composition of the present invention comprises a metal ester group-containing hydrolyzable polymer (A), zinc phosphate (B) and zinc oxide (C), and a mass ratio (B) of zinc phosphate (B) to zinc oxide (C) :C) is 20:80 to 75:25. |
