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.
Claims23
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.
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, and wherein the odor-releasing additive is a microparticle containing the odorant.
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, and wherein the odor-releasing additive is an electrochemical hydrogel containing the odorant, said odorant being releasable from the hydrogel upon substantial activation of the electro-thermal material.
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, and wherein the odor releasing additive is encapsulated in a vesicle or liposome comprising a lipid surfactant having a hydrophilic end and a hydrophobic end.
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, wherein the electro-thermal material is a salt containing ion selected from the group consisting of ammonium, sodium, potassium, nitrate, nitrite, lithium, chloride, acetate, phosphate, sulfonate, and combinations thereof;
- 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.
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, and wherein the odor-releasing additive is selected from the group consisting of microencapsulated odor-releasing agents;
- swellable odor-releasing agents;
- particulate odor-releasing agents;
- cationic, anionic, or non-ionic resin odor releasing agents;
- and combinations thereof.
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, and wherein the electro-thermal material is physically or chemically bonded to the odor-releasing additive.
