    Abstract: A magnetic field is applied to planarize magnetic pigment flakes relative to a surface. Pigment flakes, such as optically variable pigment flakes, are used in a variety of paints, inks, extrusions, powder coatings, and other forms for decorative and security applications. In many applications pigment flakes tend to align parallel to each other and to the surface to which they are applied. If the pigment flakes include a suitable magnetic structure, a magnetic field can be applied to subsequently align the flakes or enhance the alignment of the flakes in the plane of the substrate if the carrier that the flakes are dispersed in is still fluid. In some printing operations, pigment flakes that are applied parallel to the substrate are pulled out of plane when the print screen or printing die is lifted off the substrate. Application of a magnetic field can re-align pigment flakes to the plane of the substrate, enhancing the visual quality of the printed image, especially with optically variable pigments.

    Abstract translation: 施加磁场以使磁性颜料片相对于表面平坦化。 用于各种油漆，油墨，挤出物，粉末涂料和其它用于装饰和安全应用的形式的颜料薄片，例如光学可变的颜料薄片。 在许多应用中，颜料薄片倾向于彼此平行并且与它们所施加的表面对齐。 如果颜料薄片包括合适的磁性结构，则如果薄片分散在其中的载体仍然是流体，则可以施加磁场以随后对准薄片或增强薄片在基材平面中的对准。 在一些印刷操作中，当印刷屏幕或印刷模具从衬底上提起时，平行于衬底施加的颜料薄片被拉出平面。 磁场的应用可以将颜料薄片重新调整到基底的平面，增强印刷图像的视觉质量，特别是使用光学可变颜料。

    Abstract: A flake-based pigment is provided having improved specular reflectance characteristics in the visible wavelength range. The flake-based pigment has a plurality of composite reflective flakes each formed of a support layer and a reflector layer on one or both opposing sides of the support layer. This flake structure exhibits a uniaxial compressive strength much greater than a corresponding uniaxial tensile strength. The structure of the flakes provides the benefits of rigidity and brittle fracture during manufacture and application processes, which ultimately provides favorable planar and specular reflectance characteristics to the pigment in the visible wavelength range. A variety of outer coating layers can be formed around the composite reflective flakes, such as various dielectric and/or absorber layers, to produce desired optical characteristics in the pigment.

    Abstract: A color shifting multilayer interference film is provided which may be used to produce foils or flakes for use in pigment compositions and colorants having color shifting properties. The flakes can be interspersed into a pigment medium to form paints, inks, or cosmetic preparations which can subsequently be applied to objects, papers, or people. Three and five layer designs of the interference film include alternating layers of a dielectric material and carbon in various configurations. The dielectric layers are formed to have an optical thickness at a design wavelength that provides a color shift as the angle of incident light or viewing angle changes.

    Abstract: A security system includes a security article and a corresponding detector. The security article comprises a substrate layer having a top surface and a bottom surface. The substrate layer is composed of an electrically nonconductive material. Deposited on the top surface of the substrate layer is a conductive thin film coating having a predetermined electrical resistance between two spaced apart points. In one embodiment, the conductive thin film coating is comprised of a transparent conductive compound and has a thickness in a range between about 7 nanometers to about 700 nanometers. Printing can be positioned either on top of the substrate layer or on top of the thin film coating. The detector corresponds to the security article and has a light source and a pair of spaced apart probes. The detector contains electrical circuitry configured to energize the light source when an electrical resistance is produced between the probes that corresponds to the predetermined electrical resistance for the security article.
