摘要： A security article is a substrate having a diffractive grating thereon, coated with a windowed high index layer and a color shifting coating visible through the window. The color shifting coating is disposed on the high index layer or on the opposite side of the substrate. Alternatively, a thin film color shifting structure conforming the diffractive grating is disposed between the grating and the windowed high index layer, also conforming to the shape of the diffractive grating. Alternatively, an ink with low density of color shifting pigments is applied over the high index layer conforming to the shape of the diffractive grating. The resulting color shifting image provides a reference to a holographic image.

A web supporting a coating of field orientable non-spherical flakes is placed between magnets so that the fields from the magnets traverse the web. First and third magnets are provided on one side of a feedpath and a second magnet is provided between the first and third magnets on the other side of the feedpath. The first and third magnets have a same polarity and the second magnet has a complementary polarity to the first and third magnets, so that a first magnetic field spanning the feedpath is present between the first and second magnets and second magnetic field spanning the feedpath is present between the second and third magnets, wherein the magnets are positioned so that a plurality of non-spherical field orientable flakes moving along the feedpath experience a first rotation as they pass the second magnet during relative movement between the web and the magnets; The web is then moved through the fields passing the magnets and the coating is subsequently cured.

摘要： A printing apparatus includes a magnetic rotatable roller with a smooth even outer surface for aligning magnetic flakes in a carrier, such as an ink vehicle or a paint vehicle to create optically variable images in a high-speed, linear printing operation. Images can provide security features on high-value documents, such as bank notes. Magnetic flakes in the ink are aligned using magnetic portions of the roller, that can be formed by permanent magnets embedded in a non-magnetic roller body, or selectively magnetized portions of a flexible magnetic cover of the roller. In some embodiments, the roller is assembled for a plurality of interchangeable sections, which can include spinning magnets. Selected orientation of the magnetic pigment flakes can achieve a variety of illusive optical effects that are useful for decorative or security applications.

摘要： An optical structure includes a light transmissive substrate having a surface relief pattern applied thereon, such as a hologram. One or more layers can be patterned corresponding to materials playing the role of absorbers or reflectors on a Fabry-Perot type of optical structure. These materials are applied over portions of the surface relief pattern so as to form alphanumeric characters, bars codes, or pictorial or graphical designs. Additional layers may be applied to the patterned layer of the reflective or absorber materials and exposed portions of the surface relief pattern in order to provide desirable optical effects to the exposed portions of the surface relief pattern. In some embodiments, the optically active coating is a color shifting thin film, or contains color shifting flakes based on Fabry Perot designs.

摘要： The light transmitted and reflected by all-dielectric optically variable pigments varies according to viewing angle. The color travel of an all-dielectric optically variable pigment depends on amplitude changes and wavelength shifts in reflectance peaks of the pigment. The width and center wavelength of reflectance peaks can be controlled by selecting the ratio of thicknesses between high-index and low-index layers in a thin film stack. Reflectance peaks can regenerate or become suppressed and shift with tilt angle, thus providing a wide variety of color trajectories.

摘要： A security image is disclosed which is formed from flakes having a first color with flakes having a second different color mixed within a carrier uniformly. The flakes having the second color are magnetically orientable and the flakes having the first color are non-magnetic and do not align or orient in a magnetic field. By exposing at least a single coated region to a magnetic field that is substantially orthogonal to the substrate upon which the coating of flakes is coated, a visible region having the first color is provided as the magnetic flakes are upstanding and the non-magnetic flakes are lying flat upon the substrate. In another region where there is no field applied a visible region having third perceived color different from, however formed from the first color or the second color is seen.
