Abstract
Disclosed herein are printable compositions that include a UV-A blocking compound, wherein the composition is free of colorants that are visible under white light or UV light. Also disclosed herein are images formed by printing the printable composition on a substrate surface, wherein the substrate surface includes one or more Uv fluorescent materials on at least a portion thereof. Also disclosed herein are methods of forming an image on a substrate including printing a selected amount of the printable composition on top of a UV fluorescent material.
Claims13
A printable composition comprising a UV blocking compound, wherein the composition contains substantially no colorants visible under white light, and substantially no colorants that fluoresce when irradiated by UV light having a range of wavelengths that correspond to at least a portion of a range of wavelengths blocked by the UV blocking compound, wherein the printable composition is a UV curable ink, a wax-based ink, a laser toner, a 3D printer filament, or a dye sublimation ink.
An image comprising a selected pattern of UV blocking ink on a substrate surface, the substrate surface comprising one or more UV fluorescent materials on at least a portion thereof, wherein the UV blocking ink is disposed on the UV fluorescent materials;
- the UV blocking ink comprising a UV blocking compound, substantially no colorants visible under white light, and substantially no colorants that fluoresce when irradiated by UV light having a range of wavelengths that correspond to at least a portion of a range of wavelengths blocked by the UV blocking compound;
- the UV fluorescent materials exhibit fluorescence when irradiated by UV light having a range of wavelengths that correspond to at least a portion of the range of wavelengths blocked by the UV blocking compound;
- the selected pattern of UV blocking ink is applied such that variable amounts of UV blocking ink are disposed on the UV fluorescent material such that when the image is illuminated by UV light having a range of wavelengths that correspond to at least a portion of the rage of wavelengths blocked by the UV blocking compound, the image exhibits one or more of fading, shadows, or an illusion of depth on the one or more UV fluorescent materials.
