Overt security features

An overt security feature comprising:

• a) a substrate made of a material selected from the group consisting of transparent materials, light absorbing materials and combinations thereof,
• b) a color constant layer comprising magnetically oriented platelet-shaped magnetic or magnetizable pigment particles,
• c) an optically variable layer comprising a cholesteric liquid crystal polymer selectively reflecting light in the visible spectrum range and being on top of the color constant layer thus forming a first area made of a superposition of the optically variable layer and the color constant layer,
• wherein the platelet-shaped magnetic or magnetizable pigment particles of the color constant layer have substantially a same elevation angle α, said elevation angle |α| having a value between about 10° and about 45° (10°≤angle |α|≤45°).
