본 발명은 장기 방오성, 장기 내수성, 내손상성 및 장기 부착성이 우수한 방오성 복합 도막을 제공하는 것을 과제로 한다. 상기 과제를 해결하기 위해, 본 발명의 방오성 복합 도막은 에폭시 수지계 도막(P)와 가수분해형 방오도료 조성물(q)로 형성된 방오도막(Q)가 적층된 방오성 복합 도막으로서, 상기 가수분해형 방오도료 조성물(q)가 트리이소프로필실릴메타크릴레이트(i)으로부터 유도되는 구조단위(1), 2-메톡시에틸(메타)아크릴레이트(ii)로부터 유도되는 구조단위(2), 및 중합성 이중결합을 갖는 중합성 모노머(iii)(단, 트리이소프로필실릴메타크릴레이트 및 2-메톡시에틸(메타)아크릴레이트를 제외한다.)로부터 유도되는 구조단위(3)으로 이루어지는 가수분해성 공중합체(A)와, 로진류 및/또는 모노카르복실산 화합물(B)를 함유하는 것을 특징으로 한다.

    [Object] To provide an antifouling composite coating film having excellent long-term antifouling properties, long-term water resistance, damage resistance and long-term adhesion. [Solution] An antifouling composite coating film of the invention includes a stack including an epoxy resin-based coating film (P) and an antifouling coating film (Q) formed from a hydrolyzable antifouling coating composition (q), wherein the hydrolyzable antifouling coating composition (q) includes (A) a hydrolyzable copolymer including a structural unit (1) derived from triisopropylsilyl methacrylate (i), a structural unit (2) derived from 2-methoxyethyl (meth)acrylate (ii), and a structural unit (3) derived from a polymerizable monomer (iii) having a polymerizable double bond (with the proviso that triisopropylsilyl methacrylate and 2-methoxyethyl (meth)acrylate are excluded), and (B) a rosin and/or a monocarboxylic acid compound.
