摘要：

UV-curable jet inks were ejected into a color area separated by barrier ribs, then fixed by UV curing reaction to prepare LCD color filter (CF). The widths of the color strip and rib were 90 mum and 20 mum, respectively. Either adding oligomer or increasing the amount of monomers can improve ink curability. By increasing the monomer content instead of incorporating the oligomer, the curing reactivity was elevated without deteriorating the pigment dispersion stability, jetting directionality and drop size uniformity. The drop formation behaviors were observed by the image-capture system. The ejected drops showed straight trajectory and uniform size without error and missing dots. The chemical resistance of the barrier ribs was improved to avoid collapse caused by ink corrosion.
