Security element and identification document

A security element having an authenticity information item for checking a correct combination of at least two carrier parts, wherein the security element comprises at least one first partial element having a first partial information item and at least one second partial element having a second partial information item, wherein the first partial element is assignable to a first carrier part and the second partial element is assignable to a second carrier part, wherein the first partial element and the second partial element are movable from a starting position into a check position, in which the first partial element and the second partial element overlay one another, and wherein the first partial information item and the second partial information item in the check position represent said authenticity information item,

• wherein the security element further comprises at least one third partial element having a third partial information item, wherein the third partial element is assignable to a third carrier part, wherein the third partial element is movable with respect to the first partial element from a starting position into the check position in which the first partial element and the third partial element overlay one another, wherein the first partial information item and the third partial information item in the check position represent a further authenticity information item,
• wherein the first, second and third partial elements are at least one of (i) defined by an area, wherein the area of each partial element is identical and (ii) delimited by an external peripheral line running within the corresponding first, second and third carrier parts, wherein the area delimited by the peripheral line of each partial element is identical, and wherein in the check position, the first, second and third partial elements are located one above the other such that they entirely coincide,
• wherein at least one of the first partial element, the second partial element and the third partial element comprises at least one transparent or translucent region and at least one of an opaque and a semi-opaque region, wherein, in the case of an overlay, the partial information item of another partial element becomes visible through the at least one transparent or translucent region, wherein at least one of said authenticity information item and said further authenticity information item is presented or completed thereby,
• wherein the at least one transparent or translucent region comprises a window in the corresponding carrier part, wherein the at least one of the at least one opaque and the at least one semi-opaque region comprising the partial information item is provided in the window, and wherein the at least one of the a least one opaque and the at least one semi-opaque region comprising the partial information item is provided by a processing means, and
• wherein the processing means comprises at least one of:
• (i) a laser, wherein the at least one of the at least one opaque and the at least one semi-opaque region comprising the partial information item is provided by a laser-activatable additive, which is variable in terms of color by processing with the laser, and
• (ii) another laser, wherein the at least one of the at least one opaque and the at least one semi-opaque region comprising the partial information item is provided by a metal foil or plastics pigments which are locally destroyable by processing with the another laser.
