    • The invention relates to a security document (30) comprising an area (20) in which a first item of print information (21) and a second item of print information (22) are stored which, in predetermined environmental conditions, elicit an identical impression of colour such that when said predetermined environmental conditions apply, a homogeneous uniform impression of colour is elicited in said area (20). The first print information (21) and second print information (22) cannot be distinguished between as a result of said elicited impression of colour, the first print information (21) being formed by printed colour pigments with a body colour, and the second print information (22) being formed by an ink with a structural colour whose elicited impression of colour can be altered by a stimulus. The invention also relates to a method for verifying such a security document (30), and to a method for the production of same.
    • 本发明涉及一种安全文件(30),包括一个区域(20),在该区域中存储有第一项目的打印信息(21)和第二项打印信息(22),在预定的环境条件下,它引出相同的印象 的颜色,使得当所述预定的环境条件适用时,在所述区域(20)中引发均匀的均匀的颜色印象。 第一打印信息(21)和第二打印信息(22)不能作为所引起的颜色印象的结果来区分,第一打印信息(21)由具有主体颜色的打印色彩颜料形成,并且第二打印 信息(22)由具有结构颜色的墨形成,其引发的颜色印象可以通过刺激改变。 本发明还涉及一种用于验证这种安全文件(30)的方法及其制造方法。

    • The invention relates to a security element (110), comprising a substrate layer and a security structure (115) formed on the substrate layer, which is constructed having a structural color (210) comprising microcapsules (10) containing colloidal particles (13), which by means of a structural excitation comprising the creation of an electrical and/or magnetic field can be arranged and/or re-arranged in a crystal-like structure to each other. The crystal-like structure (15) has reflection and/or transmission properties for light that can be influenced and/or adjusted by way of the structural excitation. In a non-excited state, the microcapsules (10) have an increased transmission capability and reduced reflection ability for at least one wavelength in the non-visible wavelength region. In the structural excited state, in which an electrical and/or magnetic field generated by way of structural excitation exists in the region of the microcapsules (10), the microcapsules (10) have a reduced transmission capability and an increased reflection ability compared to the non-structural excited state. The invention further relates to a verification method.
    • 本发明涉及一种包括一个基片层和形成在基片层上的安全结构(115)的安全元件(110),所有这些由具有结构色(210)一种包含微胶囊(10)包含胶体粒子构建(13) 其由结构激励包括电和/或磁场的产生的装置可以被设置和/或重新布置在一个晶体状结构海誓山盟。 晶体状结构(15)具有用于能够由结构激励的方式来影响和/或调整灯的反射和/或透射性质。 在非激发状态下,微胶囊(10)具有以增加的传输能力和减少的反射能力在可见波长区域非至少一个波长。 在由结构激励的方式生成的结构兴奋状态,在其中的电和/或磁场在微胶囊(10)的区域中存在,微胶囊(10)具有减小的传输能力和增加的反射能力相较于 非结构激发态。 本发明还涉及到一种验证方法。
