Embodiment 1
[0020] Different parts by weight of black inorganic pigment (copper chrome black, purchased from Songjiang Industry, material number: 10400), magenta inorganic pigment (cadmium red compound, purchased from Songjiang Industry, material number: 10768), yellow inorganic pigment (cadmium yellow Compound, purchased from Songjiang Industry, material number: 10350), cyan inorganic pigment (chrome blue, oxide was purchased from Songjiang Industry, material number: 10294), white color inorganic pigment (titanium white, purchased from Songjiang Industry, material number: 10900 ) mixed with different fluxes (silicon oxide, aluminum oxide, lead oxide, zinc oxide, fluoride, glass powder (P8) purchased from Songjiang Industry) and placed in a high-temperature furnace, heated to 800 ° C for co-firing for 1 After 1 hour, it was cooled and solidified for 1 hour to form a glass pigment block. These glass pigment blocks co-fired by glass powder and pigment powder are pulverized to form micron-si...
Embodiment 2
[0025] Put the glass pigment with the best flux / inorganic pigment weight ratio of color density (or brightness) in Table 1 and different dispersants such as BYK-2050, BYK-165, and Deqian Enterprise-Element9850 into the ball mill, and use the above-mentioned Milling parameters form a dispersion. The average particle size, particle size distribution index (PDI), and particle size (D95, D100) of the glass pigment in the dispersion are shown in Table 2-4.

[0032] As can be seen from Table 2-4, the dispersion process can make the glass pigments miniaturized to sub-micron level.
Embodiment 3
[0034] Take the dispersions of different colors in Table 5 of Example 3 and add co-solvents (diethylene glycol dimethyl ether, ethylene glycol butyl ether, and tetraethylene glycol dimethyl ether), resin (ARU5550) and wetting agent (BYK355 ) to form an inkjet ink, the composition of which is shown in Table 5.

[0037] Note: the numerical units in Table 5 are parts by weight
[0038] The above-mentioned inkjet ink is jet-printed on the glass substrate, the jet-printed pattern is heated to 50°C and maintained for 30 minutes to remove the solvent, and finally the inkjet pattern is sintered into the glass substrate under the high-temperature sintering condition of 700°C. The physical properties of this inkjet ink are that the viscosity (cps) at 45°C is between 2 and 30, the surface tension (dyne / cm) is between 23 and 30, and the average particle size (nm) of the glass pigment powder is the same as that after sintering. The inkjet ink color den...
