Picture-backing foil with depressions and coloring materials therein

Abstract

Foil, (aluminum) is secured to a plastic backing member (Styrofoam), and depressions made in the front face of the foil, which extend into the backing member, and are held by those members. The depressions are made in a pattern to form a picture, and plastic materials are placed in the depressions, that are transparent, of different colors, and of convex shape, acting as lenses. The plastic material includes casting resin, thixotropic thickening material, a dye, and a catalyst. Another form includes a rigid backing member and a stencil secured there to, and foil over the stencil, and the depressions are made in the foil, following the pattern in the stencil. Another embodiment includes a shaping form having raised elements and foil thereover; both are placed in a mold, and plastic material in fluent form placed over the foil and enabled to expand, the plastic material then constituting the backing member. This forces the foil against the shaping form, forming the depressions in the foil, and backing member, and these together as a unit are removed from the mold, and the picture completed as in the first cases. In a further form, plastic material is placed on a glass panel to form the pictorial representation, the glass panel is placed in the open front side of a box which is otherwise closed and lined with dark velvet. The glass panel is placed with the pictorial representation disposed inwardly.
