Abstract
The present invention is drawn to odor-releasing ink-jet inks and methods for releasing odors from printed images. The ink-jet ink comprises 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.
Claims27
An odor-releasing ink-jet ink comprising:
- (a) an ink vehicle;
- (b) an effective amount of an electro-thermal material dispersed within the ink vehicle;
- and
- (c) an effective amount of an odor-releasing additive within the ink vehicle wherein an odorant is releasable from the odor-releasing additive upon activation of the electro-thermal material.
1 more element
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 a circuit between the electro-thermal odor-releasing ink and the energy source, thereby releasing an odor.
1 more element
An odor-releasing article comprising:
- (a) a substrate;
- and
- (b) an image adhered to the substrate, said image being electro-thermally conductive, and said image containing or contacting an odor-releasing substance, wherein upon electrical or thermal activation of the image, an odorant is released from the odor-releasing substance.
