ABSTRACT:
A method of applying a reflecting effect to a design drawn on a surface of material. The method comprises preparing the surface to be treated, using a preparation technique dependent upon the material. The preparation includes cleaning the surface and for certain surfaces, such as plastics, to sensitizing the surface to receive the colors to be later applied. Thereafter, the design to be applied is initially applied to the surface. A coat of varnish is applied over it. An aluminized surface is applied over that. Then the various colors of the design are applied according to the original design which had been applied beneath the coat of varnish. Once the colors have dried, a further coat of varnish is applied and microspheres of glass are strewn over the coat of varnish to be affixed therein as the varnish dries, thus obtaining a surface with a reflecting effect. A further durable coat of a flexible varnish is thereafter applied.
