Abstract

ABSTRACT OF THE DISCLOSURE
An aesthetically pleasing, artificial human nail includes a first or top and third layers formed of a urethane, in particular an oil modified urethane or uralkyd, a second thin metal layer sandwiched between the first and third layers, and a fourth or bottom layer formed of an acrylonitrile-butadiene-styrene (ABS) polymer for attaching the nail to an existing nail.

Description

This invention relates to an artificial human nail, and in particular to a multi-layered, artificial fingernail.
Multi-layered, patterned or colored artificial nails have been proposed in the past. An example of such a nail is found in U.S. Patent No. 2,816,555, which issued to C.A. Klump on December 17, 1957. Nails of this type are used by people with short nails or to replace conventional nail polish. In general, the patterns and colors available of existing nail polishes are restricted to solid colors or preformed patterns of the type described in ~.S. Patent No.
3,598,685, which issued to T. Lee et al on August 10, 1971.
The object of the present invention is to provide an aesthetically pleasing, artificial nail of the type having a precious metal appearance, i.e. a nail incorpora-ting a precious metal.
Accordingly, the present invention relates to an artificial human nail comprising a top layer of at least partially transparent plastic, a second layer formed of a metal, and a third layer of plastic, the metal of the second layer being adhered to said top and third layers.
From the foregoing, it will be appreciated that the artificial nail of the present invention is a multi-layered product produced by depositing the bottom layer of a -~
first plastic in a mold, metallizing the bottom layer, and ...... - , .. . - .. .... ... . .. . . . .. .

2rjo9770 adding a top, protective layer of plastic to the metallized bottom layer.
Preferably a precious metal is sandwiched between two layers of a urethane, and a fourth or bottom layer of plastic is provided beneath the lower layer of urethane.
The bottom layer is formed of acrylonitrile-butadiene-styrene polymer, which receives an adhesive for attaching the artificial nail to an existing fingernail. The preferred material for the nail layers sandwiching the precious metal, i.e. the top and third layers of the nail is an oil modified urethane, which is also known as an uralkyd.
The bottom layer is an acrylonitrile-butadiene-styrene polymer, which is compatible with the uralkyd, i.e. which readily bonds to the uralkyd and does not react therewith.
The second metal layer which is sandwiched between the two urethane layers is formed of a precious metal, namely -platinum, gold or silver. The metal is deposited on the top or third layer using conventional vacuum metallizing techniques, in which a thin layer of the metal is deposited on the urethane by vaporizing a metallic filament and -condensing the metal under high vacuum. The thickness of the metal layer is three to five millionths of an inch, and -film appears as an opaque, shiny layer between the urethane layers. In the absence of a thin top layer of urethane, the metal layer will quickLy become damaged or removed. Of i 2~)09~770 course, metallizing of the urethane third layer of the artificial nail would be done in a batch process as would the layering of pla~tics.
