Abstract
Disclosed is a process which comprises contacting a sulfur-containing solvent with an oxidizing agent, said sulfur-containing solvent containing odor-causing impurities, thereby reducing odor. Another embodiment of the present invention is directed to a process for preparing an ink composition which comprises: (a) contacting a sulfur-containing solvent with an oxidizing agent, said sulfur-containing solvent containing odor-causing impurities, thereby reducing odor; and (b) admixing the sulfur-containing solvent with water and a colorant, thereby forming an ink composition.
Claims24
A process which comprises contacting a sulfur-containing solvent with an oxidizing agent, said sulfur-containing solvent containing odor-causing impurities, thereby oxidizing said impurities and reducing odor.
A process which comprises contacting a sulfur-containing solvent with an oxidizing agent, said sulfur-containing solvent containing odor-causing impurities, thereby reducing odor, wherein the sulfur-containing solvent is sulfolane.
A process which comprises contacting a sulfur-containing solvent with an oxidizing agent, said sulfur-containing solvent containing odor-causing impurities, thereby reducing odor, wherein the sulfur-containing solvent is passed through a solid material comprising either (a) a solid oxidizing agent, or (b) a solid material onto the surface of which is adsorbed an oxidizing agent.
A process for preparing an ink composition which comprises:
- (a) contacting a sulfur-containing solvent with an oxidizing agent, said sulfur-containing solvent containing odor-causing impurities, thereby oxidizing said impurities and reducing odor;
- and (b) admixing the sulfur-containing solvent with water and a colorant, thereby forming an ink composition.
A process for preparing an ink composition which comprises:
- (a) contacting a sulfur-containing solvent with an oxidizing agent, said sulfur-containing solvent containing odor-causing impurities, thereby reducing odor;
- and (b) admixing the sulfur-containing solvent with water and a colorant, thereby forming an ink composition, wherein the sulfur-containing solvent is sulfolane.
A process for preparing an ink composition which comprises:
- (a) contacting a sulfur-containing solvent with an oxidizing agent, said sulfur-containing solvent containing odor-causing impurities, thereby reducing odor, and (b) admixing the sulfur-containing solvent with water and a colorant, thereby forming an ink composition, wherein the sulfur-containing solvent is passed through a solid material comprising either (a) a solid oxidizing agent, or (b) a solid material onto the surface of which is adsorbed an oxidizing agent.
A process for preparing an ink composition which comprises:
- (a) contacting a sulfur-containing solvent with an oxidizing agent, said sulfur-containing solvent containing odor-causing impurities, thereby reducing odor;
- and (b) admixing the sulfur-containing solvent with water and a colorant, thereby forming an ink composition, said process further comprising incorporating the ink composition thus prepared into an inkjet printing apparatus and causing droplets of the ink composition to be ejected in an imagewise pattern onto a substrate, wherein the printer employs an acoustic ink jet process, wherein droplets of the ink are caused to be ejected in imagewise pattern by acoustic beams.
