DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Provided is an ink for a UV curing type backlight of an LCD, which can prevent the change in quality compared to an ink for a thermosetting backlight and can improve the drying speed of the ink and the brightness of the backlight. The ink for the UV curing type backlight is produced by a process comprising the steps of: mixing tetramethoxysilane and 0.1-1.0% HCl water soln. in the wt. ratio of 2:1-3:1; adding 20-50 wt% of an acryloxy-functional silane to the mixt. 65100-04-1 and 13463-67-7 are also in the experiment. to obtain a colloidal silica soln. of which the surface is treated by the acryloxy-functional silane, wherein the acryloxy-functional silane is at least one selected from the group consisting of acryloxypropyl trimethoxy silane, acryloxypropyl triethoxy silane, methacryloxypropyl Me diethoxy silane, and etc.; adding 20-50 wt% of hexanediol diacrylate to the silica soln.; eliminating an alc. soln. and moisture; adding 5-15 wt% of epoxy acrylate, 1-5 wt% of isobutylbenzene ether, and 5-12 wt% of a filler contg. SiO2, TiO2, and BaSO4 having an av. particle size of less than 10 mm. .
