Pre-dyes and compositions comprising them |
| abstract |
One embodiment of the present invention is a method and composition comprising a novel pre-dye molecule that is colorless and stable to ordinary light. The pre-dye molecule is capable of forming a color when exposed to certain wavelengths of electromagnetic radiation. A second embodiment of the present invention is a method of converting a conventional leuco dye to a colored composition by exposing the leuco dye admixed with a radiation transorber to certain wavelengths of electromagnetic radiation. |
