Description
Technical field
The relevant a kind of composition for ink of the present invention, particularly about a kind of composition for ink that is used for ink-jet printer, this composition for ink still can keep the stability of its quality in the pyritous environment.
Background technology
In order to make the employed composition for ink of ink-jet printer, can reach good printing quality and keep stability, thereby add the incoming interface promoting agent in composition for ink in the prior art.The interface promoting agent of commonly using that composition for ink added is to use (non-ionic) compound of non-ionic type; Yet, use non-ionic type interface promoting agent in composition for ink, often cause the cloud point of ink to reduce, thereby reduce the stability of ink.
" cloud point " (cloud point) is the special property of non-ionic type interface promoting agent in the aqueous solution, when the temperature of solution raises gradually, the solubleness of non-ionic type interface promoting agent in the aqueous solution can reduce gradually, when arriving certain specified temp, it is muddy that this solution can become, and this moment, this temperature was " cloud point " of this solution.When this aqueous solution is positioned over temperature environment more than the cloud point for a long time, the situation that can be separated.
In the prior art, when composition for ink is positioned in the ink-jet printer for printing when using, if this ink-jet printer is in long-time print state, then the body temperature of this ink-jet printer can obviously raise, cause this combination of inks often to be in the pyritous environment, and situation about being separated, that is composition for ink itself becomes the solution that exists two-phase above, and no longer have single characteristic, thereby cause printing quality unstable inhomogeneous with the printing color.Only add the composition for ink of non-ionic type interface promoting agent, when storing, easily form and be separated, cause the poor qualityization of this composition for ink with the variation of envrionment temperature.
