Abstract
The present invention is drawn to odor-releasing ink-jet inks and methods for releasing odors from printed images. The ink-jet ink includes an ink vehicle; an effective amount of an electro-thermal material dispersed within the ink vehicle; and an effective amount of an odor-releasing additive within the ink vehicle wherein an odorant is releasable from the odor-releasing additive upon substantial activation of the electro-thermal material.
Claims9
A method of releasing an odor from a printed image comprising:
- (a) providing a substrate having printed thereon an image comprising an electro-thermal odor-releasing ink;
- (b) providing an energy source;
- and
- (c) completing an electric circuit between the electro-thermal odor-releasing ink and the energy source, thereby releasing an odor.
