SCHICHTANORDNUNG MIT EINER EINEN LINSENARTIGEN EFFEKT ERZEUGENDEN BEUGUNGSOPTISCH WIRKSAMEN STRUKTUR

摘要

A layer arrangement is proposed, particularly for transfer films or laminated films, which exhibits at least two superposed synthetic resin layers, between which there is provided an interface surface having a refractive structure producing a lens-like effect, the novelty claimed being a special design of the structure having a diffractive effect.
