摘要： The invention relates to a layer structure containing: (A) a first transparent radiation-engravable layer (A) with a first surface a1) and a second surface a2) which runs substantially parallel to the surface a1), said first layer (A) having a colorful or black part-engraving, said engraving being generated by means of nonionizing electromagnetic radiation (E), on the first surface a1) which forms a first outer surface of the layer structure; (B) optionally an additional transparent radiation-engravable layer (B) with a first surface b1) facing towards the first layer (A) and another surface b2) facing away from the first layer (A) and running substantially parallel to the surface b1); and (C) optionally at least one additional transparent plastic layer (C), wherein the additional layer (C) is selectively provided in one of a group of options consisting of: on the face of the first surface a1) of the layer (A), on the face of the additional surface b2) of the additional layer (B), between the two layers (A) and (B), or, in the event of additional layers (C), a combination of at least two of said options, and an image of the colorful or black part-engraving is located on the surface of the layer structure in the form of a nontransparent structural modification forming an additional outer surface of the layer structure and lying opposite the first surface a1). The invention likewise relates to the production of the layer structure as well as to a security document containing the layer structure according to the invention.
