Abstract
The invention features a process and composition for reducing or eliminating moisture in fluids suitable for use in ink jet systems without significantly changing the surface tension of these fluids. It has been discovered that mixing at least one borate ester derived from an aqueously miscible organic hydroxyl-containing compound, with a substantially non-aqueous printing medium will hygroscopically stabilize the printing medium, (maintain the printing medium substantially water-free) without significantly changing its surface tension.
Claims12
A fluid composition which has a substantially constant surface tension and which is hygroscopically stable such that it is suitable for use as an ink in ink jet systems comprising a substantially non-aqueous printing medium having at least one borate ester miscible with said printing medium and derived from an aqueously miscible organic hydroxyl-containing compound.
A method for hygroscopically stabilizing a substantially non-aqueous printing medium suitable for use in ink jet systems without substantially changing the surface tension of said printing medium comprising the step of mixing with said printing medium at least one borate ester, miscible with said printing medium and derived from an aqueously miscible organic hydroxylcontaining compound.
