A paired optically variable device comprises a substrate having a first surface (18), first and second optical devices (23, 24) carried by the first surface of the substrate in spaced-apart positions on the first surface of the substrate to permit viewing at the same time by a human eye. A first optically variable pigment (21) is disposed in the first optical device, and a second pigment (22) is disposed in the second optical device. The optical devices have the same color at one angle of incidence and have colors different from each other at all other angles of incidence.
La présente invention concerne un appareil optique doublé, variable optiquement, qui comprend un substrat comportant une première surface (18), un premier et un deuxième dispositif optiques (23, 24) supportés par la première surface du substrat, dans des positions espacées, pour qu'ils puissent être vus en même temps par un oeil humain. Un premier pigment variable optiquement (21) est placé dans le premier appareil optique et un deuxième pigment (22) est placé dans le deuxième appareil optique. Les appareils optiques ont la même couleur sous un angle d'incidence et des couleurs différentes sous tous les autres angles d'incidence.
