Abstract
A security feature for a value document, into which positives of a representation are introduced by at least one laser beam, includes at least one laser-sensitive recording layer which is transparent in the visible spectral range, light-diffracting or light-refracting structures that are arranged on a first side of the recording layer, a positive and an image-processed positive. One of the positives or the image-processed positive is introduced into the at least one recording layer by a laser beam from a first direction through the light-diffracting or light-refracting structures and is visible when viewed from the first direction. The other of the positives or the image-processed positive is introduced into the at least one recording layer by a laser beam from a second direction and is visible when viewed from the second direction.
