Abstract: The present invention describes a novel method for the formation of optically variant pigments by the coating of layers onto a substrate and the fracturing of the coated material into pigment particles after the coating operation and novel pigments produced thereby. Coating techniques such as slot die coating (especially multiple slot die coating), spin coating, meniscus coating, curtain coating, and the like have proven successful. It is preferred that multiple die slots are used to coat multiple layers in a single pass so that manufacturing costs are minimized. The use of these coating techniques, and especially multiple die slot coating, allows for many layers to be coated, with from three to fifty layers being readily possible. This offers a relatively inexpensive way of coating out a wide variety of layers, and especially the pigment materials needed for optically variable pigments, quickly and with high quality.

Abstract: Nanofibers are produced having a diameter ranging from about 4 .ANG. to 1 nm, and a nano denier of about 10.sup.-9. The use of the electro-spinning process permits production of the desired nanofibrils. These fibrils in combination with a carrier or strengthening fibers/filaments can be converted directly into nonwoven fibrous assemblies or converted into linear assemblies(yarns) before weaving, braiding or knitting into 2-dimensional and 3-dimensional fabrics. The electrospun fiber can be fed in an air vortex spinning apparatus developed to form a linear fibrous assembly. The process makes use of an air stream in a properly confined cavity. The vortex of air provides a gentle means to convert a mixture of the fibril fed directly or indirectly from the ESP unit and a fiber mass or filament into an integral assembly with proper level of orientation. Incorporation of thus produced woven products into tissue engineering is part of the present invention.
