example 1

[0024] The rear side of ground and polished glass stones made of colorless blanks has been successfully covered with optical adjustment layers, reflective layers and intervening layers. The optical adjustment layer was formed of titanium oxide with a thickness of 40 nm. This layer can be produced by reactive magnetron sputtering from a titanium target in an atmosphere of argon and oxygen at a gas pressure of 0.5 Pa. The reflective layer is formed of silver with a thickness of 80 nm, which ensures reflection of the maximum possible amount of incident light. This layer can be produced by sputtering from a silver target in an inert argon atmosphere at a pressure of 0.5 Pa. The intervening layer is formed of titanium with a thickness of 80 nm. This layer can be produced by sputtering from a titanium target in an inert argon atmosphere at a pressure of 0.5 Pa. Deposition laboratory equipment operating on the principle of magnetron sputtering was used to form the layers. Deposit...

[0026] The rear side of ground and polished glass stones made of colorless blanks has been successfully covered with optical adjustment layers, adhesive layers, reflective layers and intervening layers. The optical adjustment layer was formed of titanium oxide with a thickness of 50 nm. This layer can be produced by reactive magnetron sputtering from a titanium target in an atmosphere of argon and oxygen at a gas pressure of 0.5 Pa. The adhesive layer was formed of alumina with a thickness of 3 nm. The reflective layer is formed of aluminum bronze alloy CuAl10Fe1 with a thickness of 100 nm. This layer can be produced by sputtering from an alloy target in an inert argon atmosphere at a pressure of 0.5 Pa. The intervening layer was formed of titanium with a thickness of 40 nm. This layer can be produced by sputtering from a titanium target in an inert argon atmosphere at a pressure of 0.5 Pa. Deposition laboratory equipment operating on the principle of magnetron sputtering ...

Abstract

The invention concerns a decorative substrate, especially an artificial jewellery stone having a colour effect, being formed by a transparent substrate which comprises the following layers on the back side deposited in the following order from the back side of the substrate: an optically modifying layer, a reflection layer formed by at least one metal or by an alloy from a group including Au, Ag, Cu, Al, Cr, Ti, aluminium bronzes and alloys of Au, Ag and Cu, an interposed layer having a thickness of 10 to 100 nm and a layer of a protecting varnish. Between the optically modifying layer and the reflection layer is alternatively comprised an adhesive layers formed by at least one metal oxide from a group of metals including Al, Ti, Cr and Sn. The invention concerns also a method for achieving the colour effect for a decorative transparent substrate.

Description

technical field [0001] The invention relates to decorative substrates, in particular artificial jewelry stones with color effects, in particular imitating the coloration of natural gemstones. The invention also relates to a method for obtaining such color effects for decorative transparent substrates. The term "transparent substrate" is understood within the scope of the present invention to mean any product which is transparent in the visible light region. Such a transparent substrate can in particular be formed by a stone, advantageously an artificial transparent costume stone, for example a glass or plastic stone which is preferably not colored by any technique. For purposes of simplification of the description below, the invention will be described in terms of transparent stone jewelry, but what is stated in this context is also valid for other transparent substrates as defined above. As far as considering the color effects that need to be obtained for transparent substr...
