ABSTRACT:
Glow in the dark artwork which includes a luminescent layer formed of a luminescent material such as a fluorescent or phosphorescent paint or coated layer. The luminescent layer is secured with its luminescent surface covered by image means. The image means has an image formed on its surface via a plurality of image defining opaque and translucent areas. Opaque areas of the image means prevent photons emitted from the excited atoms of the luminescent material from passing through the opaque areas of the image means as light. Translucent areas of the image means allow photons emitted from the excited atoms of the luminescent material to pass through the translucent areas of the image means as light. In this way a glow in the dark image may be produced. Securement means is also provided for securing the luminescent layer to the image means.
