摘要： The present invention provides a process for forming a multilayer film, by applying, onto a substrate, the following three coatings: (A) a coloring base coating containing a titanium white pigment and an aluminum flake and capable of forming a film having a value of N 7 to N 9 in Munsell's color system, (B) a white-pearl-like or silver-pearl-like base coating containing a scaly mica powder coated with titanium oxide, and (C) a clear coating in this order without substantially curing the resulting films of the coatings (A), (B) and (C); as necessary conducting preliminary drying at 50.degree.-100.degree. C. between the application of the coating (A) and the application of the coating (B) and/or between the application of the coating (B) and the application of the coating (C); and heating the three films to crosslink and cure them simultaneously. The multilayer film has excellent high white-iridescent appearance, color stability, etc.
摘要翻译：本发明提供一种形成多层膜的方法，通过在基材上涂覆以下三种涂层：（A）包含钛白色颜料和铝薄片的着色底涂层，并且能够形成具有（B）白色珍珠状或银珍珠型基底涂层，其中含有涂覆有氧化钛的鳞片状云母粉末，（C）透明涂层，无需基本固化所得涂层（A），（B）和（C）的膜; 根据需要，在施加涂层（A）和施加涂层（B）之间和/或施加涂层（B）和施加涂层（B）之间，在50℃-100℃进行初步干燥 C）; 并加热三个膜同时交联和固化。该多层膜具有优异的白色虹彩外观，颜色稳定性等。

摘要： The present invention provides a process for forming a multilayer film, which comprises: applying a cationic electrocoating (A) and an intermediate coating (B) in this order, followed by heat-curing, applying thereon a coloring base coating (C) capable of forming a colored film having a value of N 7 to N 9 in Munsell's color system, applying, without curing the coloring base coating (C) applied above, an iridescent base coating (D) containing a scaly mica powder coated with titanium oxide, followed by preliminary drying at 50.degree.-100.degree. C., and applying a clear coating (E), followed by heating to subject the films of the coatings (C), (D) and (E) simultaneously to crosslinking and curing, wherein the coloring base coating (C) and the iridescent base coating (D) are each a thermosetting aqueous coating containing, as vehicle components, an acrylic resin emulsion (a), a urethane resin emulsion (b) and a crosslinking agent (c). The process can form a multilayer film superior in iridescence feeling, depth feeling, smoothness, distinctness of image gloss, etc. and is suitably used for coating of, in particular, automobile body panel.
