United States Patent 2,992,125 SHEET MATERIAL HAVING A DECORATIVE APPEARANCE Geraud Antoine Jean Fustier, Lyon, France, assignor to Society J. Bocuze & 'Cie, Lyon, France, a corporation of France No Drawing. Filed Dec. 30, 1958, Ser. No. 783,727 Claims priority, application France Jan. 9, 1958 5 Claims. (Cl. 117-7) The present invention relates to a sheet material having a special decorative appearance and adapted to a wide variety of applications from the packing and the conditioning of various products, the making of ribbons or wreaths and also of wall coatings and ornamentations of any kind. This material is characterized in that it is constituted by a base sheet made of a flexible polymerized plastic material coated with a reflecting, for instance metallic, layer which is preferably covered with a varnish and offers surface unevennesses capable of imparting to the reflected light rays phase changements and which hereby bring about the extinction of some waves lengths in relation to the incidence angle of these rays and give to the surface a iridescent appearance similar to the appearance of the Newton interference rings which may be observed on the oil puddles.

The invention is also related with a process for the making of this material which consists in submitting a sheet of flexible polymerized material having a high limit of plastic deformation to an elongation in the zone of said plastic deformation, covering these sheets with a layer of a reflecting metallic material, preferably by an evaporation in an evacuated atmosphere and annealing the sheets before or after the coating to give them a iridescent appearance.

The iridescent appearance of the sheets thus obtained which can be compared with the interference colors of the Newtons rings which may be observed on oil puddles, seems to be attributable to microscopic surface unevennesses created on the sheet of plastic material in which the large molecules elongated and submitted to strains on account of the elongation are later released by a stabilization operation and form on the reflecting surface mirco-unevennesses similar to' a difiraction lattice.

The sizes of such unevennesses are such that the light rays, reflected and difiused by the surface, offer, in relation to each other, alteration of direction and phase shifts bringing about by interference the extinction of some Wave lengths in relation to the angle of incidence of these rays.

Two alternatives of the process according to the invention are illustrated by the following flow diagrams:

In order to protect the reflecting layer, the sheets are then covered with a layer of a transparent, eventually colored varnish, which in same time allows to embellish the color formed by the reflecting surface to be improved, particularly by imparting to this surface a guilded or copper-colored-tint. In such a case, the drying of the varnish and the stabilization of the plastic material may be performed in one single step.

As above mentioned, the stabilization of the plastic material is preferably carried out after the plating, thus allowing to obtain with the utmost security the interference colors since the micro-unevennesses formed at the surface of the plastic material during the stabilization reverberate at the surface of the matallic layer which is only a few microns thick. Nevertheless, by taking suitreverberate at the surface of the metallic layer which is deposited by a volatilization in a vacuum chamber from equalizing the unevennesses, it is also possible to carry on the stabilization before the plating immediately after the elongation process.

What is claimed is:

1. A method of making sheet material having an iridescent ornamental appearance which comprises providing a sheet of resin material having a relatively thin thickness, and elongating the resultant resin sheet at least up to but not greater than its point of plastic deformation, thereafter applying a reflecting layer of metal thereover by vaporizing and condensing metal thereon under vacuum conditions, and stabilizing the sheet by subjecting the same to a temperature between about 120 to 150 C.

2. Sheet material having an iridescent ornamental appearance made in accordance with the method defined in claim 1.

*3. A method of making sheet material having an iridescent ornamental appearance which comprises providing a sheet of resin material having a relatively thin thickness, and elongating the resultant resin sheet at least up to but not greater than its point of plastic deformation, thereafter applying a reflecting layer of aluminum metal thereover by vaporizing and condensing aluminum metal thereon under vacuum conditions, and stabilizing the sheet by subjecting the same to a temperature between about 120 to 150 C.

4. A method of making sheet material having an iridescent ornamental appearance which comprises providing a sheet of resin material having a relatively thin thickness, and on the order of 3/ 100 mm, and elongating the resultant resin sheet at least up to but not greater than its point of plastic deformation, thereafter applying a reflecting layer of metal thereover by vaporizing and condensing metal thereon under vacuum conditions, stabilizing the sheet by subjecting the same to a temperature between about 120 to 150 C., and applying a protecting transparent coating over said stabilizedsheet.

5. A-methodof-making sheet material having'an iridescent ornamental appearance Which comprises providing a sheet of resin material having a relatively thin thickness, and onthe order of 3/100 mm, and elongating the resultanfresin'sheet atleast up to but not greater than its point of plastic deformation, thereafter applying a reflecting layer of aluminum metal thereover by vaporizingand condensing aluminum metal thereon under vacuum conditions, and stabilizing the sheet by subjecting the same to a temperature between about 120 to150'C.,

and applying a protecting transparent coating over said stabilized sheet.
