The invention relates to a method for producing a security element having a holographic layer in which a hologram is arranged, characterized by at least the following steps: a) providing the holographic layer; b) exposing the holographic layer at least in sections via a master hologram to produce a hologram copy in the holographic layer; e) printing the holographic layer at least in sections with an ink, forming a printed feature, wherein the ink comprises the melt of a dye or a colorless component or a solvent and a dye dissolved therein or a colorless component dissolved therein; d) fixing the exposed holographic layer to produce the hologram in the holographic layer, wherein the printed feature and the hologram are arranged in the holographic layer such that the printed feature and the hologram overlap at least in sections. The invention further relates to a security feature which is produced or can be produced by said method.
本发明涉及一种制备具有全息层的安全元素的方法,其中全息图案被排列在全息层中,其特征在于至少包括以下步骤:a)提供全息层;b)通过主全息图案至少在部分区域上曝光全息层,以在全息层中制作全息图案副本;e)使用墨水至少在部分区域上印刷全息层,形成印刷特征,其中墨水包括染料或无色成分或溶剂及其溶解的染料或无色成分的熔体;d)固定曝光的全息层,以在全息层中制作全息图案,其中印刷特征和全息图案排列在全息层中,使印刷特征和全息图案至少在部分区域上重叠。本发明还涉及通过该方法制备或可制备的安全特征。
