The invention relates to a security element for securing security papers, value documents, and other data carriers, comprising a lenticular image, which shows at least two different appearances (14A, 14B) from different directions of observation, wherein the lenticular image contains a lenticular screen (70) consisting of a plurality of microlenses (40, 60, 62, 64) and a laser-sensitive motif layer (28) arranged at a distance from the lenticular screen (70), which laser-sensitive motif layer (28) has, in two or more motif-layer partial areas (172, 174, 176, 178) different markings (30A, 30B) introduced by the action of laser radiation, which produce the at least two different appearances (14A, 14B) when the motif layer (28) is observed by means of the lenticular screen (70). According to the invention, the lenticular screen (70) is divided into two or more lenticular-screen partial areas (72, 74, 76, 78), in which the microlenses (40, 60, 62, 64) have differently refractive lens surface shapes, wherein the different lenticular-screen partial areas (72, 74, 76, 78) are congruent with the different motif-layer partial areas (172, 174, 176, 178) and the markings (30A, 30B) of the motif-layer partial areas (172, 174, 176, 178) are produced by laser application to the lenticular-screen partial areas (72, 74, 76, 78). |
