摘要： A scanning laser having a wavelength compatible with a coating binder so as to cure it as the laser scans and irradiates the coating on a moving web. A system and method for curing flakes by providing a scanning laser which scans across a moving coated substrate in a magnetic field allows images to be formed as magnetically aligned flakes are cured into a fixed position. The images have regions of cured aligned flakes. The scanning laser cures the magnetically aligned flakes within it region it irradiates. Alternatively an array of lasers can be used wherein individual lasers can be switched on and off to fix irradiated coating as a moving web is moved at a high speed.

摘要： A method of planarizing a plurality of orientable non-spherical flakes supported by a longitudinal web is disclosed. 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： An optically variable device is disclosed having a substrate with an array of pyramidal structures formed upon it or within it. The structures are preferably formed by printing pyramids with an optically variable color-shifting ink using an Intaglio-like printing process. Alternatively the structure can be formed by embossing a layer of ink with positive pyramids so as to yield an array of positive embossed pyramids. Each of the structures form a pyramidal-like having at least three slanted faces and wherein one or more than one color is seen when viewing the pyramids vary as substrate is rotated at least 30 degrees about an axis orthogonal to the substrate. In order to see a color shift the device is rotated around the surface normal of the substrate, while keeping the angle of incidence to the light source the same, and keeping the viewing angle the same. Various forms of pyramids may be used, however pyramids with planar faces are most suitable.

摘要： A security image and method of forming said image is disclosed wherein a substrate having an image or indicia thereon is coated with a dilute solution of pigment flakes in an ink or paint. The flakes are subsequently aligned in a magnetic field and are fixed after the field is applied. Most or all of the flakes in a region are aligned so as to be partially upstanding wherein their faces are essentially parallel. Coating the image with flakes yields a latent image which can be clearly seen at a small range of predetermined angles.

摘要： Diffractive pigment flakes are selectively aligned to form an image. In one embodiment, flakes having a magnetic layer are shaped to facilitate alignment in a magnetic field. In another embodiment, the flakes include a magnetically discontinuous layer. In a particular embodiment, deposition of nickel on a diffraction grating pattern produces magnetic needles along the grating pattern that allow magnetic alignment of the resulting diffractive pigment flakes. Color scans of test samples of magnetically aligned flakes show high differentiation between illumination parallel and perpendicular to the direction of alignment of the magnetic diffractive pigment flakes.

摘要： All-dielectric diffractive pigment flakes can be applied to an object to impart a diffractive effect to the object without substantially changing the background color of the object. In one case, such diffractive pigment flakes can be applied to a white object to impart a white diffractive effect. The thickness of the dielectric layers in the diffractive pigment flakes can be chosen to provide thin-film interference, as well as diffraction from the interfaces between layers patterned with a diffraction grating. In some cases, the thin-film interference can provide color shifting in addition to the diffractive effect.
