Description

Magenta red ink composition

Technical field

The present invention relates to a kind of aqueous ink compsn that is used for inkjet-printing device, particularly a kind of red aqueous ink compsn.

Background technology

According to the difference of used colorant, inkjet-printing device is divided into dye-based ink and pigmented inks usually with ink.Wherein the dye-based ink is divided into water-soluble China ink and solvent borne China ink according to its used main solvent difference.

Water-soluble China ink is main solvent with water, so its dyestuff must fully be dissolved in the water and can produce proper density and when storing over a long time, sedimentary stabilizing solution can not occur receiving on the black part to produce.For obtaining high-quality smooth emulation printing effect, also need dyestuff when bright color can be provided, to have good light permanency--light stability.Because the common color of the dyestuff that the sun-proof rank is high is dim, can not satisfy the demand of letter quality, and the common sun-proof rank of dyestuff that color becomes clear is low, fugitive color.Therefore be difficult to find the dyestuff that meets above-mentioned all requirements, make each item performance all gratifying jetting ink, particularly magenta red ink.

CN 1393493A number Chinese publication discloses a kind of high-light-fastness and water-proof red jetting ink; Its reactive red that sun-proof rank is higher 180, the bright Xylene Red 52 of color use with the active red dye combination; Though obtained photostabilization and bright color preferably; But because of the sun-proof rank of reactive red 180 has only 4 grades, and the sun-proof rank of Xylene Red 52 has only the 2-3 level, so photostabilization is still unsatisfactory.

Summary of the invention

One of the object of the invention provides the good magenta red ink composition of a kind of light fastness.

For realizing above-mentioned purpose, technical scheme provided by the invention is: magenta red ink composition, contain: rosaniline dyes mixture, organic solvent, auxiliary agent and water; Wherein, magenta red ink composition, contain: rosaniline dyes mixture, organic solvent, auxiliary agent and water is characterized in that:

Said rosaniline dyes mixture comprises the sun-proof rank more than 5 grades and be selected from least a rosaniline dyes A and sun-proof rank in reactive red 23, acid red 80, the Xylene Red 82 and be not less than 4 grades and be selected from least a rosaniline dyes B in reactive red 24, REACTIVE Red 195, reactive red 3, Xylene Red 289, the reactive red 180;

With respect to the gross weight of magenta red ink composition, the addition of said rosaniline dyes A is 1.0wt%-25.0wt%, and the addition of said rosaniline dyes B is 1.0wt%-20.0wt%, and the total addition level of said rosaniline dyes mixture is 2.0wt%-30.0wt%.

Another good again scheme is that the rosaniline dyes compsn further comprises Xylene Red 52.

Not bad scheme is the gross weight with respect to magenta red ink composition, and the addition of Xylene Red 52 is 0.1wt%-5.0wt%.

Magenta red ink composition of the present invention uses the sun-proof rank more than 5 grades and be selected from least a rosaniline dyes A in reactive red 23, acid red 80, the Xylene Red 82 through combination; Be not less than 4 grades and be selected from least a rosaniline dyes B in reactive red 24, REACTIVE Red 195, reactive red 3, Xylene Red 289, the reactive red 180 with the sun-proof rank, obtained good light fastness.In addition,, the color of magenta red ink composition of the present invention is improved, make through its image that prints to have bright color through in dye mixture, adding the bright Xylene Red 52 of color.

Embodiment

Magenta red ink composition of the present invention contains dye mixture, organic solvent, auxiliary agent and water.

It is the rosaniline dyes B that rosaniline dyes A and sun-proof rank more than 5 grades are not less than 4 grades that the rosaniline dyes mixture mainly comprises the sun-proof rank.Wherein, rosaniline dyes A is selected from least a in reactive red 23, acid red 80, the Xylene Red 82; Rosaniline dyes B is selected from least a in bright reactive red 24, REACTIVE Red 195, reactive red 3, Xylene Red 289, the reactive red 180.Through aforesaid combination, can guarantee that magenta red ink composition has the colour gamut of broad and good light fastness.The consumption of rosaniline dyes A and rosaniline dyes B can suitably be selected according to the purposes and the print characteristic of magenta red ink composition; Reasonable is gross weight with respect to magenta red ink composition; The addition of rosaniline dyes A is 1.0wt%-25.0wt%; The addition of rosaniline dyes B is 1.0wt%-20.0wt%, and the total addition level of rosaniline dyes A and rosaniline dyes B is 2.0wt%-30.0wt%.

For the color that improves magenta red ink composition to satisfy special printing demand, under the prerequisite that satisfies the sun-proof performance, can also further comprise a spot of Xylene Red 52 in the rosaniline dyes mixture.Reasonable is that with respect to the gross weight of magenta red ink composition, the addition of Xylene Red 52 is 0.1wt%-5.0wt%.

The main solvent of magenta red ink composition of the present invention is a water.In order to guarantee that magenta red ink composition has good printing stability; Also contain organic solvent in the magenta red ink composition; Like terepthaloyl moietie, glycol ether, triglycol, Ucar 35, glycerine, polyoxyethylene glycol, butanols, 1.5-pentanediol, 1.2.6-hexanetriol, acetone, methylethylketone, diacetone alcohol, pyrrolidone, N-methyl-2 pyrrolidone; Ethanol, Virahol, butanols, isopropylcarbinol, EGME, ethylene glycol ethyl ether, butyl glycol ether, glycol ether methyl ether, diethylene glycol ethyl ether, butyl carbitol, the mixture of one or more of triglycol methyl ether, triglycol butyl ether etc.

Can also contain various auxiliary agents in the magenta red ink composition of the present invention, like tensio-active agent, pH value regulator, antiseptic-germicide and intercalating agent etc.Tensio-active agent can be tween, AS or bi ion active agent etc.The pH value regulator can be sodium hydroxide, Pottasium Hydroxide, ammoniacal liquor, triethylamine, trolamine, acetic acid, lactic acid.Antiseptic-germicide can be PROXEL GXL.Intercalating agent can be EDTA.
