    摘要： A method of forming pigment flakes includes using a deposition substrate having a plurality of regions; some of the regions are raised or lowered so that there is a level difference between each two adjacent regions. A coating deposited onto this substrate breaks along region borders when it is separated from the substrate. In one embodiment, the substrate includes first and second regions, wherein each of the first regions is in an abutting relationship with at least one of the second regions. All the first regions are at a first level and all the second regions are at a second level, and the difference between the first and second levels is greater than a predetermined value. The first and second regions are preferably square-shaped regions for manufacturing square flakes with practically no debris.

    摘要： Opaque flakes, such as pigment or bright flakes used in paints and inks, have a selected shape and/or other indicia to provide a covert security feature to an object. Shaped opaque covert flakes are not readily detectable by causal observation, but in some embodiments are easily seen at 50× magnification. In manufacturing the flakes a sheet of embossed frames are provided having embossed symbols or indicia within. Upon removing a coating from the embossed sheet the coating material tends to break along frame lines or grooves and the resulting flakes are substantially uniform in size. In order to have the flakes break along frame lines or grooves more readily than along the embossing or grooves defining indicia within a frame, the frames are provided with a deeper groove than indicia grooves. As well a groove having a different shaped profile conducive to breakage can be used for the frame grooves whereas a groove having a profile less conducive to breakage can be used to form the indicia grooves. We have found that the flakes can be further protected from breakage by coating them in a protective coating. This coating may have other features which makes the logo more visible.

    摘要翻译： 不透明的薄片，例如在油漆和油墨中使用的颜料或亮片，具有选定的形状和/或其他标记，以向对象提供隐蔽的安全特征。 通过因果观察不能容易地检测出不透明的隐形薄片，但是在一些实施例中，可以容易地以50倍放大倍率。 在制造薄片时，设置有压花框架，其中具有压花符号或标记。 在从压花片去除涂层时，涂层材料倾向于沿着框线或凹槽而断裂，并且所得到的薄片的尺寸基本上是均匀的。 为了使片沿着框架线或槽更容易地沿着在框架内限定标记的压印或凹槽而断裂，框架设置有比标记凹槽更深的凹槽。 同样，具有有利于断裂的不同形状轮廓的槽也可以用于框架槽，而具有不利于断裂的轮廓的槽可用于形成标记槽。 我们已经发现，通过将薄片涂在保护涂层中，可以进一步保护薄片不被破坏。 该涂层可能具有其他特征，使徽标更加可见。

    摘要： A diffractive pigment blend or composition is provided which includes a plurality of groups of all-dielectric diffractive pigment flakes. The pigment flakes of each group each include one or more dielectric layers for providing a background color, at least one of which includes a diffractive structure for providing a diffractive effect. Each group of pigment flakes provides a different diffractive effect, and the diffractive pigment blend or composition provides a combined diffractive effect that is a combination of the different diffractive effects. The combined diffractive effect may be a neutral white diffractive effect or may include a reversal in color travel.

    摘要： In a plurality of substantially same planar pigment flakes, each flake is formed of one or more thin film layers. Each flake has a face surface and a flake border delimiting the face surface; the flake border undulates in the plane of the flake. The flakes have a pre-selected shape, may have a symbol or a grating thereon. A method of manufacturing of these flakes including the steps of: (a) providing a substrate having a plurality of one-flake regions and a plurality of depressions or protrusions disposed therebetween and not extending into the one-flake regions, (b) coating the substrate with a releasable coating, and (c) removing the releasable coating and breaking it into the flakes; wherein two adjacent of the one-flake regions are separated by at least three of the depressions or protrusions for facilitating the breaking of the releasable coating into the flakes.
