Abstract: A colorant including a mixture of pigments is disclosed. The pigments have a similar coloration but different resistance to corrosion. The mixing ratio is selected to optimize the corrosion resistance against color brightness, and/or acidic corrosion resistance against alkali corrosion resistance of the colorant.

Abstract: In a plurality of asymmetric color-shifting flakes, each flake has an asymmetric magnetic core with a magnetic layer visible on the first side of the core and a non-magnetic reflector layer on the magnetic layer, visible on the second side of the core. The flake has a spacer layer and an absorber layer on the first side of the core, and also a spacer layer and an absorber layer on the second side of the core, for providing color shifting effects. The material of the magnetic layer is different from the material of the reflector layer, and may be more stable when exposed to a chemical. When a coating with the asymmetric color-shifting flakes is exposed to the chemical, it may have better optical performance than a coating with symmetric color-shifting flakes.

Abstract translation: 在多个非对称色移薄片中，每个薄片具有非对称磁芯，磁芯在磁芯的第一侧可见，磁性层上的非磁性反射层可见于磁芯的第二侧。 薄片在芯的第一侧上具有间隔层和吸收层，并且在芯的第二侧上还具有间隔层和吸收层，用于提供颜色转换效果。 磁性层的材料与反射层的材料不同，暴露于化学物质时可能更稳定。 当具有不对称色移薄片的涂层暴露于化学品时，可能具有比具有对称色移薄片的涂层更好的光学性能。
