Customizable document for producing a security document, customized security document and production of such a security document

Abstract

According to one aspect, the invention relates to a customizable document for producing a customized security document (). The customizable document includes, according to an alternative: a layer () which can be customized by contact-free writing an opaque customization mask that is transparent in at least one transparency area (); a first multilayer film () arranged on a first side of the customizable layer (), including a layer having a high refractive index and encapsulated between two layers having a low refractive index, and structured over at least a portion of the surface thereof such as to form a first subwavelength array, characterized by a first array vector, such that the first multilayer film acts at zero order as a wavelength subtractive filter; a second multilayer film () arranged on a second side of the customizable layer, opposite the first side, including a layer having a high refractive index and encapsulated between two layers having a low refractive index, and structured over at least a portion of the surface thereof such as to form a second subwavelength array characterized by a second array vector, such that the second multilayer film acts at zero order as a wavelength subtractive filter, the first and second arrays being at least partially stacked.
