Abstract: PURPOSE: Provided are benzimidazolone-based yellow pigments which are excellent in solvent resistance and colorfastness to light and provides a high yield, and a method for preparing the same. CONSTITUTION: The benzimidazolone-based yellow pigments represented by formula 1 are characterized in that it is prepared by using amino benzimidazolone represented by formula 9, as a diazotized compound. In the formulas, R, R1 and R2 which are the same or different, are hydrogen, C1-C4 alkyl group, nitro(-NO2) group, C1-C2 alkoxy group, C1-C18 heterocycle, methyl ester(COOCH3) or halogen group such as chloro or bromo. The yellow pigments are prepared by the steps of (i) diazotizing amino benzimidazolone compound represented by formula 9; (ii) dissolving a coupler represented by formula 11 into a solvent; (iii) mixing two solutions obtained from the steps (i) and (ii) at 0-5 deg.C; and (iv) adding base to the solution mixed in the step(iii) to adjust pH to 6-7 with stirring. In the formula 11, R, R1 and R2 are the same as the above.
