<p><P>PROBLEM TO BE SOLVED: To provide black ink for correcting microscopic defects in a coloring pattern that has sufficient blackness and light shielding properties, keeps corrected portions from becoming conspicuous, produces no protrusion that could cause new problems even if it is applied to void portions, i.e., white defects, prevents spots from spreading after application and increasing areas overlapping with normal color pixel portions, maintains good stability of physical properties such as ink viscosity during use and storage, keeps low the rate of decrease in volume after application, and makes it possible to make a film thickness sufficiently thick where it is applied to void portions; a method for correcting microscopic defects in a coloring pattern using the black ink; and a color filter manufactured using them. <P>SOLUTION: The black ink for correcting microscopic defects in a coloring pattern contains at least red, yellow and blue coloring agents, a polymer, a monomer having a reactive functional group, and a solvent, with the solvent being blended by 25 to 70 wt.% of the entire ink, and the viscosity of the ink being 40 to 300 mPa sec. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
