Background technology
The color of printing is the light of the paper reflection seen, so the three primary colors of pigment are exactly the color that can absorb RGB, is blue or green, pinkish red, yellow, and they are exactly the complementary color of RGB.As yellow uitramarine and green pigment are mixed, because yellow uitramarine absorbs blue light, therefore the green pigment absorptive red light only has green light to reflect, and Here it is, and yellow uitramarine adds that green pigment forms green reason.
The printer Yellow ink powder is one of three primary colors ink powder, and usually by solvent, colorant, surfactant, the one-tenth such as pH adjusting agent, drier and other necessary adjuvant are grouped into.Yet, the present Yellow ink powder that uses fade very fast and color relatively poor, needing to be unfavorable for long-term storage and a large amount of the printing.
Summary of the invention
The invention provides a kind of printer color toner, it is pigment that this color toner adopts inorganic oxide, the gorgeous and stable in properties of this Yellow ink powder color, and long-term storage still can be stablized the performance effect, is particularly useful for a large amount of printing speeds.
A kind of printer color toner, described color toner are Yellow ink powder, and described Yellow ink powder contains yellow uitramarine, and described yellow uitramarine is comprised of following component by mass parts:
Printer of the present invention, is comprised of following component by mass parts with the preferred described yellow uitramarine of color toner:
Printer of the present invention, is comprised of following component by mass parts with the preferred described yellow uitramarine of color toner:
Printer of the present invention accounts for 0.5% ~ 5% of ink powder gross mass with the content of the preferred described yellow uitramarine of color toner.
Printer of the present invention accounts for 2% ~ 5% of ink powder gross mass with the content of the preferred described yellow uitramarine of color toner.
Printer of the present invention by mass percentage, is comprised of following component with the preferred described ink powder of color toner:
Printer of the present invention by mass percentage, is comprised of following component with the preferred described ink powder of color toner:
Printer of the present invention is water soluble resin with the preferred described resin of color toner.
Printer of the present invention is salicylic acid metal complex with the preferred described charge adjusting agent of color toner.
Printer of the present invention preferably prepares as follows with antiforging ink powder:
I. be transferred in extrusion moulding apparatus after mixing in kneading device except the raw material of silicon dioxide, carry out extrusion molding under 120 ℃ ~ 180 ℃;
II. with the coarse crushing of step I gained fragment to mean grain size 50 μ m, further pulverize as below mean grain size 5 μ m subsequently;
III. Step II gained particle is mixed with silicon dioxide, after making its mobility be at least 20%, pulverized 200 mesh sieves.
The invention has the beneficial effects as follows: a kind of printer color toner, described color toner are Yellow ink powder, and described Yellow ink powder contains yellow uitramarine, and described yellow uitramarine is comprised of following component: La by mass parts
