PURPOSE: To easily produce a color panel by an ink-jet method, to obtain high accuracy for deposition of the ink and to improve transparency, anti-blotting property and resistance against light of pixels to be produced by adding specified monoazo dyes or a complex salt dye of a mixture of these monoazo dyes and chromium atoms into an ink. CONSTITUTION: A red ink contains at least monoazo dyes expressed by formula or a complex salt dye comprising a mixture of these monoazo dyes coupled with chromium atoms by 2:1 molar ratio. In formula, R1 and R2 are hydrogen atoms or groups selected from NO2 , SO3 M and SO2 NH2 , R3 is selected from hydrogen atom, Cl, CH3 , NO2 , SO2 and NHC2 H5 , R4 is a hydrogen atom or a part of group of atoms to form a benzene ring with R3 and R4 , R5 is a methyl group or phenyl group, R6 is a hydrogen atom or SO3 M, R7 is selected from hydrogen atom, SO3 M and SO2 NH2 , and M is alkali metal, ammonium or org. ammonium. |
