CAS号:

性质:含有金属片状颜料(特别是铝粉)和/或似金属片状颜料(特别是云母系珠光颜料)和域纳米级透明氧化物颜料(特别是超细TiO2和超细ZnO)等所谓效应颜料以及其他透明程度较大的彩色颜料的涂膜,随观察角度的不同而能闪现出明度和色调不同的颜色的一种光学效应,是由效应颜料对入射光的不同散射和反射方式所致。当几乎垂直于涂膜观察时,涂膜显示出面色(face colour或top colour),也称正规色(face colour);当几乎平行于涂膜观察时,涂膜闪现出掠视色(flop colour或down-flop colour),它是面色的补色;当视角位于上述两个极端位置之间的任一角度时,涂膜闪现出闪视色(f1ash colour)。可用变角色度计测定之。这一效应已于20世纪80年代初(铝粉-云母系珠光颜料系统)和80年代末(铝粉-超细TiO2-云母系珠光颜料系统)用于高级轿车的涂装,成为现代豪华型高级轿涂装的一个新潮流。
