| 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 exposure to light, a pH sensitive dye which changes color in response to a change in proton levels, a water compatible non-ionic wetting 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 response to said change of proton levels; wherein said base, progenitor, dye, wetting agent, thickening agent and flow aid all cooperate to provide an ink which changes color upon exposure to ultraviolet radiation and is of suitable consistency for use in a printing machine. |
