    • PROBLEM TO BE SOLVED: To provide a paint composition for forming a coating film changing from a non-colored coating film to a bright-colored coating film when light incident angle is changed to the normal of the surface of the coating film. SOLUTION: The paint composition contains (A) a glitter material having an angle-dependent interference effect and (B) a mica and/or alumina flake coated with a metal oxide in the content ratio ((A)/(B)) of the component (A) to the component (B) of 2.5/1 to 1/6 in a solid mass ratio. In the paint composition, an interference color of the component (A) and an interference color of the component (B) in the face angle of the coating film obtained by applying the paint composition are in a complementary color relation and the color of the coating film changes from an achromatic color to a chromatic color when an observation angle of the coating film obtained by applying the paint composition is changed from a face angle to a grazing angle.

    • 要解决的问题:提供一种涂料组合物,用于当光入射角变为涂膜表面法线时,形成从无色涂膜变为亮色涂膜的涂膜。 解决方案:涂料组合物含有(A)具有角度干涉效应的闪光材料和(B)以含量比((A)/(B))涂覆金属氧化物的云母和/或氧化铝薄片, )成分(A)与成分(B)的比例为2.5 / 1〜1/6。 在涂料组合物中,通过涂布涂料组合物得到的涂膜的面角度中的组分(A)的干涉色和组分(B)的干涉色在颜色关系上是互补的,涂层的颜色 当通过施加涂料组合物获得的涂膜的观察角度从面角变为掠入角时,膜从无色颜色变为彩色。 版权所有(C)2010,JPO&INPIT
