    Abstract: Elemento decorativo (2), donde el elemento decorativo (2) presenta un microestructura (4) que por luz incidente y/o por luz transmitida genera un efecto óptico, donde la microestructura (4), en una primera área (31, 32), presenta una superficie base (40) y varios elementos base (41), los cuales respectivamente presentan una superficie de elemento (411) elevada o rebajada con respecto a la superficie base (40), y un flanco (140) dispuesto entre la superficie del elemento (411) y la superficie base (40), donde la superficie base (40) de la microestructura define un plano base extendido a través de ejes de coordenadas x e y, donde las superficies de elemento (411) de los elementos base (41) respectivamente se extienden esencialmente de forma paralela con respecto al plano base, y donde en al menos una o varias primeras zonas (333, 351) de la primera área (31, 32), las superficies de elemento (411) de los elementos base (41) y la superficie base (40) están distanciadas en una dirección que se extiende perpendicularmente con respecto al plano base, en la dirección de un eje de coordenadas Z, con una primera distancia (61), la cual está seleccionada de modo que, en particular a través de interferencia de la luz reflectada en la superficie base y en las superficies de elemento, por luz incidente y/o en particular a través de interferencia de la luz transmitida a través de las superficies de elemento y las superficies base, por luz transmitida, se genera un primer color en una o en varias primeras zonas (333, 351), donde la microestructura está configurada de modo que la misma genera el primer color en el primer orden de difracción o en la luz dispersa, y donde la ocupación media de la superficie del plano base con los elementos base (41) en la primera área se ubica entre 30 % y 70 %, preferentemente entre 40 % y 60 %, y de modo aún más preferente aproximadamente en 50 %, caracterizado porque en la primera área (31, 32) los elementos base (41) se suceden unos a otros periódicamente.

    Abstract: A decorative element (2), more particularly in the form of a transfer film, a laminating film or a security thread, and a security document comprising a decorative element and a method for producing same are described. The decorative element (2) has a microstructure (4) that generates an optical effect in reflected light and/or in transmitted light. The microstructure (4) has in a first region (32) a base surface (40) and a plurality of base elements (41), which each have an element surface elevated or recessed relative to the base surface (40) and a flank arranged between the element surface and the base surface (40). The base surface (40) of the microstructure defines a base plane spanned by coordinate axes x and y. The element surfaces of the base elements (41) each run substantially parallel to the base plane. In at least one or a plurality of first zones of the first region (32), the element surfaces of the base elements (41) and the base surface (40) are spaced apart, in a direction running perpendicularly to the base plane (40) in the direction of a co-ordinate axis z, at a first distance, chosen such that more particularly as a result of interference of the light reflected at the base surface and the element surfaces in reflected light and/or more particularly as a result of interference of the light transmitted through the element surfaces and the base surface in transmitted light, a colour is generated in the one or the plurality of first zones, and wherein the base elements (41) are shaped and arranged in the first region (31, 32) in such a way that, by means of the base elements (41), the incident light is deflected by scattering and/or by diffraction from direct reflection or direct transmission or the zeroth order of diffraction in such a way that a second colour different from the first colour, more particularly a second colour complementary to the first colour, is generated upon viewing in direct reflection or direct transmission or in the zeroth order of diffraction.
