Color changing inkjet ink composition |
摘要 |
An ink jet ink composition includes an organic solvent in an amount between 60% and 95% by weight of the ink composition, a binder resin, a stabilizing agent, which may be provided by the binder resin, and a pH sensitive dye. An image formed by the ink composition changes from a first color to a second color when exposed to water, wherein the first color is different than the second color. |

1. An ink jet ink composition to be applied by an ink jet printer, the ink jet composition comprising:
an organic solvent in an amount between 60% and 95% by weight of the ink composition; a binder resin; at least one stabilizing agent, which optionally is provided by the binder resin; a pH sensitive dye, wherein an image formed by the ink composition changes from a first color to a second color when exposed to an aqueous solution, wherein the first color is different from the second color; and a conductive agent of salts such that the ink jet composition has a conductivity greater than 200 microSiemens. |
