    • The present invention teaches a composition which provides gas, flavor, and aroma barrier to substrates, where the composition is formed by mixing an ethylenically unsaturated acid and a polyamine, wherein said polyamine optionally has a crosslinker reacted therein, and wherein said polyamine has four or more A, B, or C units, where: A is an —R2—N(R1)2 unit, B is an —R1—N(R2—)2 unit, and C is an (—R2)3N— unit, where: R1 is independently selected from hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, arylalkyl, and alkylaryl, and R2 is independently selected from the group consisting of: linear or branched alkylene groups or substituted alkylene groups having from 1 to 18 carbon atoms, and arylene groups or substituted arylene groups having from 6 to 18 carbon atoms. The composition is coated on a substrate then optionally treated to initiate a free radical reaction. The invention can be applied as a coating to a variety of substrates used in packaging applications.

    • Various methods of producing a security document or article including a diffractive optical microstructure are disclosed. One method includes applying an opacifying layer (102) to at least one surface of a transparent substrate (100). An area of the opacifying layer (102) is exposed to laser radiation (108) to ablate apertures (110) in selected portions of the opacifying layer (102), thereby forming a diffractive optical microstructure (112) on the surface of the substrate (100). The laser radiation may be patterned prior to exposing the opacifying layer (102), for example by passing the radiation through a mask (104). Alternatively, a focussed or collimated laser beam (206) may be directed onto the selected portions of the opacifying layer (102). Laser radiation may be directed onto the opacifying layer (102) either directly, or through the transparent substrate (100). Security documents or articles made in accordance with the method are also provided.
    • 公开了生产包括衍射光学微结构的安全证件或制品的各种方法。 一种方法包括将不透明层(102)施加到透明基板(100)的至少一个表面。 不透明层(102)的区域暴露于激光辐射(108)以在不透明层(102)的选定部分中烧蚀孔(110),从而在基底表面上形成衍射光学微结构(112) 100)。 在暴露不透明层(102)之前,可以将激光辐射图案化,例如通过使辐射通过掩模(104)。 或者,聚焦或准直的激光束(206)可以被引导到不透明层(102)的选定部分上。 激光辐射可以直接或通过透明基底(100)引导到遮光层(102)上。 还提供了按照该方法制作的安全文件或物品。

    • A security document or device (30) is provided which has a substrate (31) including at least one layer (35,37) of polymeric material and an optical component formed by at least one orientating (PPN) layer (34) and at least one liquid crystal polymer (LCP) layer (36) in contact with the orientating layer (34). An intermediate prime layer (38) is provided between the optical component and the substrate (31) which improves the adhesion of the optical component to the substrate (31). The prime layer (38) may include a hydroxyl terminated polymer which is cross-linked by a multifunctional isocyanate. A security document with such a prime layer between the optical component and a polymeric surface of the substrate is more robust and able to withstand rough treatment without significantly affecting the optical properties of the optical component.
    • 提供了一种安全文件或装置(30),其具有包括至少一个聚合物材料层(35,37)的基底(31)和由至少一个取向(PPN)层(34)形成的至少一个 一个与取向层(34)接触的液晶聚合物(LCP)层(36)。 在光学部件和基板(31)之间提供中间原色层(38),其改善了光学部件对基板(31)的粘附性。 初级层(38)可以包括通过多官能异氰酸酯交联的羟基封端的聚合物。 在光学部件和基板的聚合物表面之间具有这样的主要层的安全文件更加坚固并且能够经受粗略处理而不会显着影响光学部件的光学性质。
