Document Type and Number:
Japanese Patent JP2012237003
Kind Code:
A
Abstract:
To provide a new multi-layer effect pigment.
The multilayer effect pigment includes a transparent substrate, a layer of high refractive index material on the substrate, and alternating layers of low refractive index and high refractive index materials on the first layer, the total number of layers being an odd number of at least three, all adjacent layers differing in refractive index by at least about 0.2 and at least one of the layers having an optical thickness which is different from all of the other layers. The resulting multi-layer effect pigment is not a quarter-wave stack.
