| titleOfInvention | Phototranschromic ink |
| abstract | A phototranschromic ink suitable for use in a printing machine, including a water soluble, inert, non-ionic polymeric resin carrier base having film forming properties, a photo acid or photo base progenitor which releases or takes up protons upon expo-sure to light, a pH sensitive dye which changes color in response to a change in proton levels, a water compatible non-ionic wet-ting agent which cooperates with said dye to allow said dye to change color in response to said change in proton levels, a water compatible non-ionic thickening agent which cooperates with said dye to allow said dye to change color in response to said change in proton levels, a neutral water soluble flow aid which cooperates with said dye to allow said dye to change color in re-sponse to said change of proton levels; wherein said base, progenitor, dye, wetting agent, thickening agent and flow aid all coop-erate to provide an ink which changes color upon exposure to ultraviolet radiation and is of suitable consistency for use in a printing machine. |
