  [Problem] To provide an antifouling paint composition which, while reducing volatile organic compounds (VOCs), has good coating workability at low temperatures as well as at room temperature, and which is capable of forming coating films having excellent mechanical strength and good long-term antifouling properties. [Solution] The two-component hydrolyzable antifouling paint composition includes two liquids that are a first component and a second component, the first component being a liquid including a reaction mixture (A) including a polyester resin (a3) obtained by polycondensation of an acid component (a1) and a polyhydric alcohol component (a2), and an acetoacetyl group-containing compound (B), the second component being a liquid including zinc oxide (C), the solid component of the reaction mixture (A) having an acid value and a hydroxyl value of 50 to 200 mgKOH/g and 100 mgKOH/g or less, respectively, and the two-component antifouling paint composition substantially not containing copper and copper compounds.

  [问题]提供一种防污漆组合物，该组合物在减少挥发性有机化合物（VOC）的同时，在低温和室温下均具有良好的涂装作业性，并且能够形成具有优异机械强度和良好长期防污性能的涂膜。 [解]双组分可水解防污漆组合物包括两种液体，即第一组分和第二组分，第一组分是一种液体，包括反应混合物（A），其中聚酯树脂（a3）由酸组分（a1）和多元醇组分（a2）缩聚而成、和含乙酰乙酰基的化合物 (B)，第二组分为液体，包括氧化锌 (C)，反应混合物 (A) 的固体组分的酸值和羟值分别为 50 至 200 mgKOH/g 和 100 mgKOH/g 或以下，双组分防污漆组合物基本上不含铜和铜化合物。
