Patent ID: 7729026

Claim:
An optically variable article comprising: a substrate having a first surface and a second surface; first and second optical devices having different optical properties formed on first and second regions, respectively, carried by the first surface or the second surface of the substrate, one of the first and second optical devices being optically variable and forming a pair with the other of the first and second optical devices, wherein said first and second optical devices are carried by the substrate in spaced-apart positions to permit viewing at the same time by the human eye, wherein said first and second optical devices appear to the human eye to have the same matching color at one angle of incidence between 0 degrees and 90 degrees for a color match angle and being without color match at other angles of incidence, wherein the first optical device comprises a diffractive optical structure having a diffractive pattern defined therein or thereon ,wherein the second optical device is diffractive or color shifting or is comprised of reflective flakes in a tinted carrier, wherein the diffractive optical structure includes magnetically aligned diffractive flakes.
