Abstract (en)
[origin: WO2015086711A2] The invention relates to a security document (30) comprising an area (20) in which a first item of print information (21) and a second item of print information (22) are stored which, in predetermined environmental conditions, elicit an identical impression of colour such that when said predetermined environmental conditions apply, a homogeneous uniform impression of colour is elicited in said area (20). The first print information (21) and second print information (22) cannot be distinguished between as a result of said elicited impression of colour, the first print information (21) being formed by printed colour pigments with a body colour, and the second print information (22) being formed by an ink with a structural colour whose elicited impression of colour can be altered by a stimulus. The invention also relates to a method for verifying such a security document (30), and to a method for the production of same.
