    • A covert material for printing onto a printing medium is provided, the covert material comprising a covert pigment and a binder encapsulating the covert pigment into a particle, where the binder comprises at least one of cellulose acetate butyrate (CAB), butyral vinyl acetate, acetyl butyrate, and acetate butyrate. Alternatively, the binder comprises at least one of polyester, polyolefin, acetyl butyrate, acetate butyrate, polystyrene copolymer, and polystyrene-polyvinylpyridine. The covert material can comprise additional components, such as ethyl acetate and/or n-propyl acetate. In one embodiment, the covert pigment comprises about 0.5-5% of the covert material. In one embodiment, the binder comprises about 5-30% of the covert material. In one advantageous embodiment, the covert pigment comprises at least 2% of the covert material and the binder comprises about 20-25% of the covert material. The covert material can further comprise at least one of a colorant, a surface additive, and a magnetic particle. The covert material can be part of a toner or ink. In at least some embodiments, the particle can have many different sizes, including sizes greater than 1 micron, greater than 5 microns, and greater than 20 microns. In one embodiment, the covert printing material is constructed and arranged to be printed using a printer having a predetermined resolution, wherein the particle has a size that is substantially the same as the size of a single pixel or dot printed using the predetermined resolution. The covert material can be constructed and arranged to satisfy a predetermined number of the NCITS 322 tests.
    • 提供用于印刷到打印介质上的隐蔽材料,所述隐蔽材料包括隐蔽颜料和将所述隐蔽颜料包封成颗粒的粘合剂,其中所述粘合剂包含乙酸丁酸纤维素(CAB),丁缩醛乙酸乙烯酯,乙酰基 丁酸酯和乙酸丁酸酯。 或者,粘合剂包括聚酯,聚烯烃,丁酸乙酰酯,乙酸丁酸酯,聚苯乙烯共聚物和聚苯乙烯 - 聚乙烯吡啶中的至少一种。 隐蔽材料可以包含另外的组分,例如乙酸乙酯和/或乙酸正丙酯。 在一个实施方案中,隐蔽颜料包含约0.5-5%的隐蔽材料。 在一个实施方案中,粘合剂包含约5-30%的隐蔽材料。 在一个有利的实施方案中,隐蔽颜料包括至少2%的隐蔽材料,并且粘合剂包含约20-25%的隐蔽材料。 隐蔽材料可进一步包括着色剂,表面添加剂和磁性颗粒中的至少一种。 隐蔽材料可以是调色剂或墨水的一部分。 在至少一些实施方案中,颗粒可以具有许多不同的尺寸,包括大于1微米,大于5微米和大于20微米的尺寸。 在一个实施例中,隐形印刷材料被构造和布置成使用具有预定分辨率的打印机进行印刷,其中所述颗粒具有与使用预定分辨率打印的单个像素或点的尺寸基本相同的尺寸。 可以构造和布置隐蔽材料以满足预定数量的NCITS 322测试。

    • The present invention relates to identification documents and smart cards. In one implementation, we provide a smart identification document including a document core. The document core is printed and laminated. The laminated core is milled to create a cavity. An integrated circuitry module is provided in the cavity. In one implementation, the cavity includes an upper cavity and a lower cavity. A laminate layer houses the upper cavity while the lower cavity extends into the document core. The upper cavity's aperture exceeds the aperture of the lower cavity resulting in a ledge in the laminate layer. A portion of the module may rest on the ledge, while another portion of the module may extend into the lower cavity. In another implementation, we provide a contactless smart card including a multi-layered structure. The structure includes a carrier layer including the smart card electronics. The carrier can be permeable (like a mesh or scrim) so that additional layers may be laminated into or through the carrier layer. A multi-layer structure provides a enhanced durability and helps protect the smart card electronics. In still another implementation, we provide a PET-based identification document. The PET-based document includes favorable durability and earth-friendly characteristics.
    • 本发明涉及识别文件和智能卡。 在一个实现中,我们提供了一个包含文档核心的智能识别文档。 文件核心印刷和层压。 将层压芯铣削以形成空腔。 在空腔中设置集成电路模块。 在一个实施方案中,空腔包括上腔和下腔。 层叠层容纳上腔,而下腔延伸到文件芯中。 上腔的孔径超过下腔的孔径,导致层压层中的凸缘。 模块的一部分可以搁置在凸缘上,而模块的另一部分可以延伸到下腔中。 在另一个实现中,我们提供一种包括多层结构的非接触式智能卡。 该结构包括包括智能卡电子装置的载体层。 载体可以是可渗透的(如网状物或稀松布),使得可以将另外的层层压到载体层中或穿过载体层。 多层结构提供了增强的耐用性,并有助于保护智能卡电子设备。 在另一个实施中,我们提供一个基于PET的识别文件。 基于PET的文件包括有利的耐久性和地球友好的特性。
