Description
The cross reference of related application
The application requires the rights and interests of the U.S. Provisional Patent Application sequence number 60/615,129 of submission on October 1st, 2004.
Invention field
A kind of ink for ink-jet print with the printed images that improves weather resistance that provides is provided.More particularly, the present invention relates to a kind ofly when on porous print media, printing, the ink for ink-jet print that improves weather resistance is provided.
Background of invention
Ink for ink-jet print typically be included in ink vehicle for example in the water-base ink vehicle as the pigment or the dyestuff of tinting material.In ink for ink-jet print, whether use the decision of pigment or dyestuff, depend on specific printing application, because every kind of tinting material all provides specific advantage and deficiency.Dyestuff is normally water miscible, and this makes that the preparation dye-based ink-jet inks is relatively easy.Yet, when contacting with water or moisture or being exposed to wherein, thicken unclear usually or wearing and tearing with the image of dye-based ink-jet inks printing.With the image of dye-based ink-jet inks printing also to visible light, UV-light or sunlight instability.On the contrary, with make of dye-based ink-jet inks those compare the more water-fast and sun-proof of making of the pigment-based ink jet ink of printed images.Yet pigment can not infiltrate printed medium, still rests on its surface.Therefore, printed images has low moisture-proof dirt (resistanceto wet smudge) and low anti-outline-color (highlighter resistance).In addition, it is very difficult obtaining and keeping the homodisperse of pigment, because pigment is not soluble in ink vehicle.Be stable dispersion pigment, in ink for ink-jet print, added dispersion agent, for example polymeric dispersant or tensio-active agent. in addition, with SURFACTANT ADSORPTION or cover on the pigment, to improve dispersiveness.Yet adding polymeric dispersant or tensio-active agent has increased viscosity, and has influenced the printing of ink for ink-jet print.In addition, when printing on porous print media, these pigment-based ink jet inks can not be made competent image.
For improving the dispersiveness of pigment in ink vehicle, advised pigment is carried out chemical modification. by with organo-functional group, for example small molecules or polymkeric substance are attached to surface of pigments and pigment are carried out chemical modification.Comprise the pigment through modification, a problem that particularly has the ink for ink-jet print of the micromolecular pigment through modification that is attached to its surface is that when printing on porous print media, it can not produce competent image.Therefore, for the weather resistance of increase is provided, in ink for ink-jet print, used polymeric additive on these printed mediums.Yet the use of these polymeric additives has caused ink for ink-jet print viscosity to rise, and this has reduced its printing, optical density(OD) (" OD ") and moisture-proof dirt.
A kind of pigment-based ink jet ink need be provided, when it prints, demonstrate the wet dirty weather resistance of improvement on porous print media, and do not reduce OD.
