Provided is a paint composite film which comprises anatase-type titanium oxide, exhibits photocatalytic activity and generates active oxygen even in visible light and weak light rays, has a self-cleaning effect, and effectively blocks the invasive action of activated oxygen on interior surfaces. Also provided is a method for manufacturing the paint composite film comprising anatase-type titanium oxide. The present invention, in which a peroxotitanic acid solution serves as an A solution and an anatase-type titanium oxide dispersion solution obtained by heating the A solution to 70-200°C serves as a B solution, is characterized by providing: an exterior-use composite film having a photocatalyst layer and obtained by applying and drying the B solution, which has photocatalytic activity, on an undercoat layer formed by applying and drying the A solution, to which reinforcing particles have been added and an interior-use composite film having antimicrobial activity even in dark places and obtained by applying and drying the B solution, to which a precious metal has been added, on an undercoat layer formed by applying and drying the A solution.提供一種含有銳鈦型氧化鈦之塗飾用複合膜及其製造方法,即使是可視光或微弱光線仍具有光觸媒活性而產生活性氧,具有自清作用,並且有效阻斷活性氧對基材的侵害。 本發明的特徵為提供外飾用複合膜以及內飾用複合膜,過氧鈦酸水溶液設為A液,A液加熱到70至200℃製作的銳鈦型氧化鈦分散液設為B液,外飾用複合膜係在塗佈了加入強化粒子的A液予以乾固之底塗層上,塗佈具有光觸媒活性的B液予以乾固而具有光觸媒層;內飾用複合膜係在塗佈了A液予以乾固之底塗層上,塗佈加入貴金屬的B液予以乾固而即使在暗處仍具有抗菌活性。1‧‧‧光觸媒層2‧‧‧底塗層3‧‧‧強化粒子4‧‧‧凸部5‧‧‧凹部6‧‧‧基材7‧‧‧露出部10‧‧‧光觸媒複合膜20‧‧‧光觸媒複合膜(局部磨損)
