The specification describes articles which have a three-dimensional appearance even though they comprise a two-dimensional representation of an object. The effect can be achieved by coating the two-dimensional representation with a protective coating of a clear resin of clear plastics material, having a convex external surface. The articles may be buttons or jewellery that have the appearance of being made from gem stones such as opal.

DETAILED DESCRIPTION What is claimed is: 1.
An article comprising a two dimensional reproduction of a surface of an object on a sheet of transparent material, a reflective backing, and a protective coating of a clear resin or clear plastics material for protecting the sheet of transparent material; the reflective backing, the protective coating and the sheet of transparent material being so arranged that the two dimensional reproduction has a three dimensional appearance.
2.
The article according to claim 1 wherein the two dimensional reproduction is a photographic reproduction.
3.
The article according to claim 1 wherein the two dimensional reproduction is a drawn simulation on a diffraction grating that simulates a surface of the object when light passes through the protective coating and is diffracted and reflected by the diffraction grating.
4.
The article according to claim 1 wherein the protective coating is a clear thermosetting resin.
5.
The article according to claim 4 wherein the clear thermosetting resin is a epoxy resin.
6.
The article according to claim 1 wherein the protective coating is a poly(meth)acrylate.
7.
The article according to claim 1 wherein the article is a button.
8.
The article according to claim 1 wherein the object is a gemstone.
9.
The article according to claim 8 wherein the gemstone is an opal.
10.
An article comprising a two dimensional reproduction of a surface of an object on a sheet of suitable material with a reflective backing and a protective coating of a clear resin of clear plastics material, the protecting coating being formed with a convex external surface so that the two dimensional reproduction has three dimensional appearance thereby creating an image of the object.
11.
The article according to claim 10, wherein the two dimensional reproduction is a photographic reproduction.
12.
The article according to claim 10 wherein the two dimensional reproduction is a drawn simulation on a diffraction grating that simulates a surface of the object when light passes through the protective coating and is diffracted and reflected by the diffraction grating
