Ink-jet ink for color filter and method for preparing the same and method for preparation of color filter

摘要

The disclosure provides an ink-jet ink for color filter and a method for preparing the same, as well as a method for preparing of a color filter. The ink-jet ink for color filter comprising, by weight, 10 to 50 parts of aqueous nano pigment dispersion and 51 to 95 parts of a cold curing component.

主权项

1. A method for preparing an ink-jet ink for color filter, comprising:
mixing 5 wt % to 40 wt % of styrene, 1 wt % to 30 wt % of a (meth)acrylic ester monomer, 0.5 wt % to 5 wt % of an acidic monomer, 0.25 wt % to 5 wt % of a cross-linking monomer, 0.05 wt % to 0.5 wt % of an emulsifier adjuvant, and 0.05 wt % to 0.5 wt % of an oil soluble initiator so as to form a mixture, and adding 0.5 wt % to 10 wt % of an organic pigment or dye, and optionally 0.05 wt % to 0.5% of a nucleating promoter to the mixture to obtain an oil phase solution after being dissolved; dissolving 0.05 wt % to 2 wt % of an emulsifier and 0.05 wt % to 2 wt % of buffering agent to 40 wt % to 90 wt % of deionized water to obtain an aqueous phase solution; mixing the oil phase solution with the aqueous phase solution to obtain a fine emulsion after agitation and homogenization; heating the fine emulsion to an reaction temperature, adding 0.05 wt % to 0.5 wt % of a water soluble initiator to initiate polymerization, after the polymerization adjusting pH value to 9˜10, and obtaining an aqueous nano pigment dispersion by filtration; and adding a cold curing component to the aqueous nano pigment dispersion, and mixing evenly to obtain the ink-jet ink for color filter.
