    • A curable, powder-based coating composition is disclosed. The coating composition is utilized for coating a substrate, having a first color effect, with a film layer of the coating composition. Application of the film layer to the substrate produces a second color effect different from the first color effect of the substrate. The coating composition includes a powder-based binder. The powder-based binder is the reaction product of a resin and a cross-linking agent. More specifically, the resin has a functional group and the cross-linking agent is reactive with the functional group of the resin. The coating composition also includes a color effect-providing pigment. The color effect-providing pigment includes a pigment substrate and an inorganic coating. More specifically, the pigment substrate has first and second substantially parallel and planar surfaces, and the inorganic coating is disposed on at least one of the first and second substantially parallel and planar surfaces, and the inorganic coating is disposed on at least one of the first and second substantially parallel and planar surfaces of the pigment substrate. Furthermore, the inorganic coating disposed on the pigment substrate has an index of refraction of 1.8 or less.
    • 公开了一种可固化的粉末涂料组合物。 涂料组合物用于涂覆具有第一颜色效果的基材与涂料组合物的膜层。 将薄膜层施加到基底产生不同于基底的第一颜色效应的第二颜色效果。 涂料组合物包括粉末状粘合剂。 粉末状粘合剂是树脂与交联剂的反应产物。 更具体地说,树脂具有官能团,交联剂与树脂的官能团反应。 涂料组合物还包括着色效果颜料。 着色效果颜料包括颜料基材和无机涂层。 更具体地,颜料基材具有第一和第二基本上平行和平坦的表面,并且无机涂层设置在第一和第二基本上平行和平面的表面中的至少一个上,并且无机涂层设置在第一和第二表面中的至少一个上 和颜料基底的第二基本上平行和平坦的表面。 此外,设置在颜料基材上的无机涂层的折射率为1.8以下。
