V-SHAPED (NON PLANAR) MAGNETIC EFFECT PIGMENTS

Effect pigment comprising a plurality of layers (26, 27, 28, 30, 31, 32) and a magnetic element (29), having a nonplanar configuration with at least two segments (3, 4, 9, 10, 24, 25) which joint at an angle, one side of the at least two segments (3, 4, 9, 10, 24, 25) possessing the same optical pro...

Zusammenfassung:Effect pigment comprising a plurality of layers (26, 27, 28, 30, 31, 32) and a magnetic element (29), having a nonplanar configuration with at least two segments (3, 4, 9, 10, 24, 25) which joint at an angle, one side of the at least two segments (3, 4, 9, 10, 24, 25) possessing the same optical properties to an opposing side of another of the at least two segments (3, 4, 9, 10, 24, 25), and at least two of the plurality of layers (26, 27, 28, 30, 31, 32) having an asymmetrical configuration, wherein the pigment produces more than one optical effect, regardless of the face on which the pigment falls on the substrate. The different optical effects are perceived according as the pigment is looked at from the left or from the right or if a document printed with an ink comprising the effect pigments is rotated along its perpendicular axis.
