Abstract
A member, such as a sheet of paper or plastic, is coated with phosphorescence glow on the dark material and then layered or coated with photographic emulsion so that an image can be produced on the surface of the member by a photographic process, and thereafter, an image can be produced on the surface by illumination means. In another form of the invention, a sheet of paper or plastic has luminescent material incorporated therein to cause one side of the sheet of material to glow in the dark. The sheet is assembled onto a clipboard and thereby provides means by which a written message can easily be formed in the dark.
Claims6
A method of providing a glow-in-the-dark image on wallpaper comprising the steps of:
- providing a sheet of phosphorescent material suitable for subsequent use as wallpaper that glows in the dark when illuminated and thereafter viewed in the dark;
- applying a coating of photosensitive emulsion over one surface of said sheet of phosphorescent material;
- providing a glow-in-the-dark image on said one surface of said sheet of phosphorescent material by selecting said image and thereafter imagewise exposing and processing said photosensitive emulsion to produce said image;
- wherein said sheet of material can be exposed to light and thereafter said image can be viewed in the dark.
A method of providing a glow-in-the-dark image on a sheet of material by making a self-supporting sheet of phosphorescent material suitable for subsequent use as wallpaper that glows in the dark when first illuminated and immediately thereafter viewed in the dark, said method comprising:
- making said self-supporting sheet of material by applying a coating of photosensitive emulsion over one surface of a sheet of phosphorescent material;
- providing said glow-in-the-dark image on said one surface of said sheet of phosphorescent material by selecting said image and thereafter imagewise exposing and processing said photosensitive emulsion to produce said image;
- wherein said sheet of phosphorescent material can be exposed to light and immediately thereafter said image can be viewed in the dark.
