Document Type and Number:
WIPO Patent Application WO/2005/000973
Kind Code:
A1
Abstract:
A benzimidazolone compound is disclosed which has a plurality of hues in a single structural formula and good dispersibility in a binder resin and thus is useful as a pigment. The benzimidazolone compound is further useful as a pigment since it suffers little aggregation even when two or more kinds of the compound having different hues are used at the same time for obtaining an aimed hue. The benzimidazolone compound is represented by the following general formula (1): (wherein R1, R2, R3 and R4 independently represent a hydrogen atom, an alkyl group having 1-5 carbon atoms or an alkoxy group having 1-5 carbon atoms; and R5 and R6 independently represent an alkyl group having 1-5 carbon atoms).
