The present invention relates to a kind of ink for ink-jet print, particularly relate to the carmetta ink for ink-jet print of a kind of high-light-fastness (light-fastness) and water tolerance (water-fastness).
Background of invention
In the ink cartridge of color inkjet printer ccontaining ink for ink-jet print generally included magenta ink (magenta ink), foreign blue ink (cyan ink), yellow ink (yellow ink) and black ink (blackink).But in recent years, the ink of light color series appears again in the ink for ink-jet print in the ink cartridge of being sold on the market, for example shallow fuchsin (light magenta) ink, blue (light cyan) ink in shallow ocean, light yellow (light yellow) ink make the color representation of spray ink Printing get abundanter beauty.
With regard to the colorant (colorant) that produces ink color, mainly be divided into dyestuff (dye) and pigment (pigment) two classes.Wherein, the composition of the ink of color inkjet printer is mostly based on water-base dye (water-base dye).Therefore compare with pigment, dyestuff and water have intermiscibility preferably, and also dyestuff is relatively poor for the fastness of water, and make that the water tolerance of image is desirable not to the utmost behind the spray ink Printing.In addition, because dyestuff can cause photochemical reaction because of the irradiation of light, so-called " photochemical reaction " is the reaction that absorbs luminous energy and cause, mainly be divided into photochemistry and decompose (Photolysis), photochemistry synthetic (Photo-synthesis) and photochemical sensitization (Photo-Sensitization), so that cause colorant to produce the phenomenon of fading, reduce the photostabilization of dyestuff.Though pigment has splendid water tolerance, but pigment all is not so good as the bright in luster of dyestuff on brightness (lightness of color), form and aspect (hue) and the chroma (chroma) of color, and pigment particle size is bigger, can't be dispersed in the solution, pigment is condensed in ink for ink-jet print and produce precipitation, cause the shower nozzle of ink cartridge to produce the situation of blocking (clogging), influence printing quality.
Goal of the invention
In view of this, purpose of the present invention will provide a kind of high-light-fastness and water-proof carmetta ink for ink-jet print exactly, wherein reactive orchil 180 (reactive red 180), phloxine 52 (acid red52) and reactive orchil (reactive red) collocation, can reduce fading extent on the one hand because of the caused ink for ink-jet print of illumination, strengthen the photostabilization of ink for ink-jet print, can strengthen the fastness of ink for ink-jet print on the other hand for water, improve the water tolerance of ink for ink-jet print, and then improve printing quality.
