摘要:
In a method for improving the optical separation of needle-shaped fluorescent layers, made from a fluorescent material, which are formed by vapor deposition on a substrate, vapor deposition is controlled so that the fluorescent layer is deposited on the substrate with a density which is reduced in comparison to the density that the fluorescent material has as a solid.

The present invention relates to methods for imprinting solid particles onto materials that enhance the performance characteristics, such as the odor adsorption capacity, of the material. The present invention uses a xerographic imprinting method to apply a toner formulation to the material. The toner formulation typically includes solid particles (e.g., activated carbon), binding agents, and additives. Using this method, a specific pattern can be imprinted onto the material. The present invention can also use a Gravure method to imprint performance enhancing solid particles onto a material. This method advantageously provides precise control over the volume of mixture (e.g., solid particles and binding agent) impressed onto the material. In addition, this method can imprint specific patterns of mixture onto the material.

In the generalized method of the present invention a heat curable coating is first applied to an article of manufacture. Thereafter, an outer coating is applied to the article in a physical vapor deposition process, and the heat from the PVD process cures the first layer while the PVD coating is being deposited upon the article. In the preferred embodiments, the heat curable coating is a powder coating and the cathodic arc of the PVD process provides the heat that cures the powder coating. An infrared heat source within the PVD chamber may be utilized to preheat the powder coating which is typically composed of an epoxy-polymer compound. Articles of manufacture having the coating of the present invention formed thereon are manufactured with less energy and labor costs.
