DIFFRACTIVE PIGMENT FLAKES AND COMPOSITIONS

摘要

Diffractive pigment flakes include single layer or multiple layer flakes tha t have a diffractive structure formed on a surface thereof. The multiple layer flakes can have a symmetrical stacked coating structure on opposing sides of a reflective core layer, or can be formed with encapsulating coatings around t he reflective core layer. The diffractive pigment flakes can be interspersed in to liquid media such as paints or inks to produce diffractive compositions for subsequent application to a variety of objects. The diffractive pigment flak es can be formed with a variety of diffractive structures thereon to produce selected optical effects.
